In this step by step tutorial I will demonstrate you how to Generate unique Slug URL in laravel. Please follow the instruction given below:

Step 1: Download New Laravel Project
Step 2: Update Database Details
Step 3: Create Migration and Model
Step 4: Create Controller File
Step 5: Register New Route
Step 6: View App in Browser

Download New Laravel Project

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

composer create-project --prefer-dist laravel/laravel laravel-demo

1	composer create-project --prefer-dist laravel/laravel laravel-demo

Update Database Details

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=DB_Name
DB_USERNAME=DB_Username
DB_PASSWORD=DB_Password

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=DB_Name

DB_USERNAME=DB_Username

DB_PASSWORD=DB_Password

Create Migration and Model

Now, in this step we will create model and migration file. Please run the following command:

php artisan make:model Blog -m

1	php artisan make:model Blog -m

Now open app/Models/Blog.php file, and define the values that you want to add in database table.

<?php

namespace App\Models;

use Illuminate\Support\Str;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;


class Blog extends Model
{
    use HasFactory;
    
    protected $fillable = [ 
        'title', 
        'slug',
        'details' 
    ];

    public $timestamps = false;

    protected static function boot()
    {
        parent::boot();
        static::created(function ($blog) {
            $blog->slug = $blog->initSlug($blog->title);
            $blog->save();
        });
    }

    private function initSlug($title)
    {
        if (static::whereSlug($slug = Str::slug($title))->exists()) {
            $max = static::whereName($title)->latest('id')->skip(1)->value('slug');
            if (isset($max[-1]) && is_numeric($max[-1])) {
                return preg_replace_callback('/(\d+)$/', function($mathces) {
                    return $mathces[1] + 1;
                }, $max);
            }
            return "{$slug}-1";
        }

        return $slug;
    }
}

<?php

namespace App\Models;

use Illuminate\Support\Str;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Blog extends Model

{

use HasFactory;

protected $fillable = [

'title',

'slug',

'details'

];

public $timestamps = false;

protected static function boot()

{

parent::boot();

static::created(function ($blog) {

$blog->slug = $blog->initSlug($blog->title);

$blog->save();

});

}

private function initSlug($title)

{

if (static::whereSlug($slug = Str::slug($title))->exists()) {

$max = static::whereName($title)->latest('id')->skip(1)->value('slug');

if (isset($max[-1]) && is_numeric($max[-1])) {

return preg_replace_callback('/(\d+)$/', function($mathces) {

return $mathces[1] + 1;

}, $max);

}

return "{$slug}-1";

}

return $slug;

}

Open create_blogs_table.php migration file and update the function up() method as following:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateBlogsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('blogs', function (Blueprint $table) {
            $table->id();
            $table->string('title', 120);
            $table->string("slug", 120);
            $table->text('details');             
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('blogs');
    }
}

<?php

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

class CreateBlogsTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('blogs', function (Blueprint $table) {

$table->id();

$table->string('title', 120);

$table->string("slug", 120);

$table->text('details');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('blogs');

}

Create Controller File

Now, lets create a controller named BlogController using command given below –

php artisan make:controller BlogController

1	php artisan make:controller BlogController

Once the above command executed, it will create a controller file BlogController.php in app/Http/Controllers/ directory. Open the BlogController.php file and put the following code in it.

app/Http/Controllers/BlogController.php

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Blog;


class BlogController extends Controller
{
    public function index()
    {
        $blog = Blog::create([
            "title" => "The demo is in process",
            "slug" => "laravel-multiple-slug-urls-example",
            "details" => "Here is the slug demo"
        ]);

        dd($blog);
    }

}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\Blog;

class BlogController extends Controller

{

public function index()

{

$blog = Blog::create([

"title" => "The demo is in process",

"slug" => "laravel-multiple-slug-urls-example",

"details" => "Here is the slug demo"

]);

dd($blog);

}

Register New Route

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\BlogController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
*/

Route::get('/blog', [BlogController::class, 'index']);

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\BlogController;

|--------------------------------------------------------------------------

| Web Routes

|--------------------------------------------------------------------------

Route::get('/blog', [BlogController::class, 'index']);

Run Development Server

Now we are ready to run our example so lets start the development server using following artisan command –

php artisan serve

1	php artisan serve

Now, open the following URL in browser to see the output –

http://127.0.0.1:8000/blog

1	http://127.0.0.1:8000/blog

In this tutorial you will learn to use already exists validation rules in laravel form input field. In this article I will share example to use already exists validation rules in laravel form. We will implement server side validation for already exists validation rules in laravel. Suppose if you want to check the student name already exists in database table before you want to save it in database. In this case we can use exists validation rule to check if student with given name is already exists in database.

How to Add Exists Validation in Laravel 8 Input Field

In this step by step tutorial I will demonstrate you with example how to add and use exists validation rules in laravel forms. Please follow the instruction given below:

Step 1: Create Laravel Project
Step 2: Add Database Credentials
Step 3: Build Model and Migration
Step 4: Run Database Migration
Step 5: Create Controller File
Step 6: Register New Routes
Step 7: Create Blade View File
Step 8: Test Laravel App

Create Laravel Project

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

composer create-project laravel/laravel --prefer-dist laravel-demo

1	composer create-project laravel/laravel --prefer-dist laravel-demo

Add Database Credentials

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db_name
DB_USERNAME=db_username
DB_PASSWORD=db_password

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=db_name

DB_USERNAME=db_username

DB_PASSWORD=db_password

Build Model and Migration

Now, in this step we will create model and migration file. Please run the following command:

php artisan make:model Student -m

1	php artisan make:model Student -m

Now, open app/Student.php model file and put the following code in it:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Student extends Model
{
    use HasFactory;
    public $fillable = [
        'student_name',
    ];    
}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Student extends Model

{

use HasFactory;

public $fillable = [

'student_name',

];

}

Open create_students_table.php migration file and update the function up() method as following:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateStudentsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('students', function (Blueprint $table) {
            $table->id();
            $table->string('student_name');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('students');
    }
}

<?php

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

class CreateStudentsTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('students', function (Blueprint $table) {

$table->id();

$table->string('student_name');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('students');

}

Run Database Migration

Now, run the migration to create database table using following artisan command:

php artisan migrate

1	php artisan migrate

Create Controller File

Now, lets create a controller named StudentController using command given below –

php artisan make:controller StudentController

1	php artisan make:controller StudentController

Now, add the code in the app/Http/Controller/StudentController.php.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Student;


class StudentController extends Controller
{
    public function index() {
        return view('welcome');
    }

    public function store(Request $request) {
       $validator = $this->validate($request, [
          'student_name' => 'required|exists:students,created_at'
       ]);

       if($validator) {
        Student::create($request->all());
       }
       
       return back()->with('success', 'Student has been added.');
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\Student;

class StudentController extends Controller

{

public function index() {

return view('welcome');

}

public function store(Request $request) {

$validator = $this->validate($request, [

'student_name' => 'required|exists:students,created_at'

]);

if($validator) {

Student::create($request->all());

}

return back()->with('success', 'Student has been added.');

}

Register New Routes

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\StudentController;

/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
| Here is where you can register API routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| is assigned the "api" middleware group. Enjoy building your API!
|
*/

Route::get('/', [StudentController::class, 'index']);

Route::post('form', [StudentController::class, 'store'])->name('student.validate');

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\StudentController;

|--------------------------------------------------------------------------

| API Routes

|--------------------------------------------------------------------------

| Here is where you can register API routes for your application. These

| routes are loaded by the RouteServiceProvider within a group which

| is assigned the "api" middleware group. Enjoy building your API!

Route::get('/', [StudentController::class, 'index']);

Route::post('form', [StudentController::class, 'store'])->name('student.validate');

Create Blade View File

In this step we will create a blade view file, open the resources/views/welcome.blade.php file and put the following code in it:

<!DOCTYPE html>
<html>

<head>
    <meta charset="utf-8">
    <title>Laravel Exists Validation Example</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet">
</head>

<body>
    <div>
        <form action="{{ route('student.validate') }}" method="post">

Expo React Native Retrieve Data from Firebase Tutorial

In this Expo React Native Retrieve Data from Firebase Tutorial I will show you how to fetch data from firebase/firestore data collection in react native application. In this tutorial you will learn to Retrieve data from firebase/firestore in react native application. In this article I will share example to get data from firebase data collection in react native application.

Expo React Native Retrieve Data from Firebase Tutorial

In this step by step tutorial I will demonstrate you with example on how to retrieve data from firebase in react native application. Please follow the instruction given below:

Step 1: Install Expo CLI
Step 2: Create Expo React Native App
Step 3: Create Firebase Project
Step 4: Set Up Firebase in React Native
Step 5: Install React Native Elements Package
Step 6: Fetch Data
Step 7: Add Component in App Js
Step 8: Run App on Device

Install Expo CLI

Before staring with this tutorial you must have installed Node 12 LTS or greater version. Now, use npm or yarn to begin installing the Expo CLI.

# npm
npm install -g expo-cli

# yarn
yarn global add expo-cli

# npm

npm install -g expo-cli

# yarn

yarn global add expo-cli

Create Expo React Native App

Now, run the following command to download and install new React Native application.

expo init RnBlogProject

1	expo init RnBlogProject

let’s switch into the newly created project directory using following command:

cd RnBlogProject

1	cd RnBlogProject

Create Firebase Project

Go to firebase.google.com site, create a new firebase project for react native. Creating Firebase account from Firebase dashboard. Click on “Create a project” button and create a brand new Firebase project. We will require firebase configuration details to make the connection between react native and Firebase database.

Set Up Firebase in React Native

In this step you need to install a firebase expo package to be installed in your react native app.

expo install firebase

1	expo install firebase

Expos app requires the dotenv package to installed, so use the following command to install the package.

npm install dotenv

1	npm install dotenv

Lets create a .env file at the root of your react native app. Now, put the firebase credentials in it as following:

apiKey: "****************************",
authDomain: "****************************",
projectId: "****************************",
storageBucket: "****************************",
messagingSenderId: "****************************",
appId: "****************************"

apiKey: "****************************",

authDomain: "****************************",

projectId: "****************************",

storageBucket: "****************************",

messagingSenderId: "****************************",

appId: "****************************"

Now rename your app.json file to app.config.js and put the following code in it:

import 'dotenv/config';

export default {
  expo: {
    name: 'RnBlog',
    slug: 'RnBlog',
    version: '1.0.0',
    orientation: 'portrait',
    icon: './assets/icon.png',
    splash: {
      image: './assets/splash.png',
      resizeMode: 'contain',
      backgroundColor: '#ffffff'
    },
    updates: {
      fallbackToCacheTimeout: 0
    },
    assetBundlePatterns: ['**/*'],
    ios: {
      supportsTablet: true
    },
    android: {
      adaptiveIcon: {
        foregroundImage: './assets/adaptive-icon.png',
        backgroundColor: '#FFFFFF'
      }
    },
    web: {
      favicon: './assets/favicon.png'
    },
    extra: {
      apiKey: process.env.apiKey,
      authDomain: process.env.authDomain,
      projectId: process.env.projectId,
      storageBucket: process.env.storageBucket,
      messagingSenderId: process.env.messagingSenderId,
      appId: process.env.appId
    }
  }
};

import 'dotenv/config';

export default {

expo: {

name: 'RnBlog',

slug: 'RnBlog',

version: '1.0.0',

orientation: 'portrait',

icon: './assets/icon.png',

splash: {

image: './assets/splash.png',

resizeMode: 'contain',

backgroundColor: '#ffffff'

updates: {

fallbackToCacheTimeout: 0

assetBundlePatterns: ['**/*'],

ios: {

supportsTablet: true

android: {

adaptiveIcon: {

foregroundImage: './assets/adaptive-icon.png',

backgroundColor: '#FFFFFF'

}

web: {

favicon: './assets/favicon.png'

extra: {

apiKey: process.env.apiKey,

authDomain: process.env.authDomain,

projectId: process.env.projectId,

storageBucket: process.env.storageBucket,

messagingSenderId: process.env.messagingSenderId,

appId: process.env.appId

}

};

Now we will create a config directory, within this we will create a firebase.js file and put the following code in it:

import * as firebase from 'firebase';
import firestore from 'firebase/firestore';

const firebaseConfig = {
  apiKey: "****************************",
  authDomain: "****************************",
  projectId: "****************************",
  storageBucket: "****************************",
  messagingSenderId: "****************************",
  appId: "****************************"
};

firebase.initializeApp(firebaseConfig);

firebase.firestore();

export default firebase;

import * as firebase from 'firebase';

import firestore from 'firebase/firestore';

const firebaseConfig = {

apiKey: "****************************",

authDomain: "****************************",

projectId: "****************************",

storageBucket: "****************************",

messagingSenderId: "****************************",

appId: "****************************"

};

firebase.initializeApp(firebaseConfig);

firebase.firestore();

export default firebase;

Now go to Firebase database and click on the Firestore Database. Here, you need to create a students collection and add some data with name and designation properties.

Install React Native Elements Package

In this step, use the following command to install the react native elements package.

npm install react-native-elements

1	npm install react-native-elements

Fetch Data

In this step, we will fetch data from the firestore database and display firebase data in react native app. Lets create a components/ directory, inside this folder create fetchlist_screen.js file and put the following code in it:

import React, { Component } from 'react';

import { StyleSheet, ScrollView, ActivityIndicator, View } from 'react-native';
import { ListItem } from 'react-native-elements';
import firebase from '../config/firebase';


class FetchListScreen extends Component {

    constructor() {
        super();
        this.docs = firebase.firestore().collection('students');
        this.state = {
          isLoading: true,
          students: []
        };
      }
    
      componentDidMount() {
        this.unsubscribe = this.docs.onSnapshot(this.getStudentsData);
      }
    
      componentWillUnmount(){
        this.unsubscribe();
      }
    
      getStudentsData = (querySnapshot) => {
        const students = [];
        querySnapshot.forEach((res) => {
          const { name, designation } = res.data();
          students.push({
            key: res.id,
            name,
            designation
          });
        });
        this.setState({
          students,
          isLoading: false
       });
      }
    
    
    
      render() {
        if(this.state.isLoading){
          return(
            <View style={styles.loader}>
              <ActivityIndicator size="large" color="red"/>
            </View>
          )
        }    
        return (
          <ScrollView style={styles.wrapper}>
              {
                this.state.students.map((res, i) => {
                  return (
                    <ListItem 
                       key={i}           
                       bottomDivider>
                      <ListItem.Content>
                        <ListItem.Title>{res.name}</ListItem.Title>
                        <ListItem.Subtitle>{res.designation}</ListItem.Subtitle>
                      </ListItem.Content>
                      <ListItem.Chevron 
                         color="black" 
                      />
                    </ListItem>
                  );
                })
              }
          </ScrollView>
        );
      }
    }
    
    const styles = StyleSheet.create({
      wrapper: {
       flex: 1,
       paddingBottom: 22
      },
      loader: {
        position: 'absolute',
        alignItems: 'center',
        justifyContent: 'center',    
        left: 0,
        right: 0,
        top: 0,
        bottom: 0,
      }
    })

export default FetchListScreen;

import React, { Component } from 'react';

import { StyleSheet, ScrollView, ActivityIndicator, View } from 'react-native';

import { ListItem } from 'react-native-elements';

import firebase from '../config/firebase';

class FetchListScreen extends Component {

constructor() {

super();

this.docs = firebase.firestore().collection('students');

this.state = {

isLoading: true,

students: []

};

}

componentDidMount() {

this.unsubscribe = this.docs.onSnapshot(this.getStudentsData);

}

componentWillUnmount(){

this.unsubscribe();

}

getStudentsData = (querySnapshot) => {

const students = [];

querySnapshot.forEach((res) => {

const { name, designation } = res.data();

students.push({

key: res.id,

name,

designation

});

this.setState({

students,

isLoading: false

});

}

render() {

if(this.state.isLoading){

return(

</View>

)

}

return (

{

this.state.students.map((res, i) => {

return (

<ListItem

key={i}

bottomDivider>

<ListItem.Content>

<ListItem.Title>{res.name}</ListItem.Title>

<ListItem.Subtitle>{res.designation}</ListItem.Subtitle>

</ListItem.Content>

<ListItem.Chevron

color="black"

</ListItem>

);

})

}

</ScrollView>

);

}

const styles = StyleSheet.create({

wrapper: {

flex: 1,

paddingBottom: 22

loader: {

position: 'absolute',

alignItems: 'center',

justifyContent: 'center',

left: 0,

right: 0,

top: 0,

bottom: 0,

}

})

export default FetchListScreen;

Add Component in App Js

In this step we will move to the App.js file and register the newly created component in it.

import React from 'react';
import FetchListScreen from './components/fetchlist_screen.js'

export default function App() {
  return (
    <FetchListScreen/>
  );
}

import React from 'react';

import FetchListScreen from './components/fetchlist_screen.js'

export default function App() {

return (

);

}

Run App on Device

Now, we are ready to check the app on the smartphone. You must have installed the Expo Client on your smartphone. Download the expo from Google Play Store or App Store.

# npm
npm start

# yarn
yarn start

# npm

npm start

# yarn

yarn start

Now, you need to scan the QR code on your browser or console screen using the expo app. Your development machine and smartphone must be on same network.

Install Laravel 8

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

composer create-project --prefer-dist laravel/laravel blog

1	composer create-project --prefer-dist laravel/laravel blog

Database Configuration

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=here your database name(blog)
DB_USERNAME=here database username(root)

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=here your database name(blog)

DB_USERNAME=here database username(root)

DB_PASSWORD=here database password(root)

Create Migration

Now, in this step we will create model and migration file. Please run the following command:

php artisan make:migration create_products_table --create=products

1	php artisan make:migration create_products_table --create=products

Once this command is executed you will find a migration file created under “database/migrations”. lets open migration file and put following code in it –

<?php
  
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
  
class CreateProductsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->text('detail');
            $table->timestamps();
        });
    }
  
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('products');
    }
}

<?php

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

class CreateProductsTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('products', function (Blueprint $table) {

$table->id();

$table->string('name');

$table->text('detail');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('products');

}

Now, run following command to migrate database schema.

php artisan migrate

1	php artisan migrate

Add Resource Route

routes/web.php

use App\Http\Controllers\ProductController;
  
Route::resource('products', ProductController::class);

use App\Http\Controllers\ProductController;

Route::resource('products', ProductController::class);

Add Controller and Model

In this step we will create controller and model file using the following artisan command:

php artisan make:controller ProductController --resource --model=Product

1	php artisan make:controller ProductController --resource --model=Product

After that you will find new file in this path “app/Http/Controllers/ProductController.php”.In controller we will have following seven methods by default as shown below.

1)index()
2)create()
3)store()
4)show()
5)edit()
6)update()
7)destroy()
put the following code in ProductController.php file.

app/Http/Controllers/ProductController.php

<?php
  
namespace App\Http\Controllers;
   
use App\Models\Product;
use Illuminate\Http\Request;
  
class ProductController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $products = Product::latest()->paginate(5);
    
        return view('products.index',compact('products'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }
     
    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('products.create');
    }
    
    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
            'name' => 'required',
            'detail' => 'required',
        ]);
    
        Product::create($request->all());
     
        return redirect()->route('products.index')
                        ->with('success','Product created successfully.');
    }
     
    /**
     * Display the specified resource.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function show(Product $product)
    {
        return view('products.show',compact('product'));
    } 
     
    /**
     * Show the form for editing the specified resource.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function edit(Product $product)
    {
        return view('products.edit',compact('product'));
    }
    
    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, Product $product)
    {
        $request->validate([
            'name' => 'required',
            'detail' => 'required',
        ]);
    
        $product->update($request->all());
    
        return redirect()->route('products.index')
                        ->with('success','Product updated successfully');
    }
    
    /**
     * Remove the specified resource from storage.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function destroy(Product $product)
    {
        $product->delete();
    
        return redirect()->route('products.index')
                        ->with('success','Product deleted successfully');
    }
}

<?php

namespace App\Http\Controllers;

use App\Models\Product;

use Illuminate\Http\Request;

class ProductController extends Controller

{

/**

public function index()

{

$products = Product::latest()->paginate(5);

return view('products.index',compact('products'))

'detail' => 'required',

]);

Product::create($request->all());

return redirect()->route('products.index')

->with('success','Product created successfully.');

}

/**

public function edit(Product $product)

{

return view('products.edit',compact('product'));

}

/**

* @return \Illuminate\Http\Response

public function update(Request $request, Product $product)

{

$request->validate([

'name' => 'required',

'detail' => 'required',

]);

$product->update($request->all());

return redirect()->route('products.index')

->with('success','Product updated successfully');

}

/**

* @param \App\Product $product

* @return \Illuminate\Http\Response

public function destroy(Product $product)

{

$product->delete();

return redirect()->route('products.index')

->with('success','Product deleted successfully');

}

Now, open the model file located at “app/Models/Product.php” and put following code in it:

app/Models/Product.php

<?php
  
namespace App\Models;
  
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
  
class Product extends Model
{
    use HasFactory;
  
    protected $fillable = [
        'name', 'detail'
    ];
}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Product extends Model

{

use HasFactory;

protected $fillable = [

'name', 'detail'

];

}

Add Blade Files

Lets create following blade files:

1) layout.blade.php

2) index.blade.php

Laravel 8 Form Validation Example

In this Laravel 8 form validation example tutorial I’ll show you how to validate form data in laravel 8 application. In this laravel form validation tutorial you will learn to validate laravel form with built in laravel validation available in laravel. In this Laravel 8 form validation tutorial I’ll share various validation implementation and use case.

Laravel comes many built-in validation rules that can be easily implemented. In this example, we have used some of following validation rules –

required:- It set input field is required.
min:- Validate minimum character length.
max:- Validate maximum character length.
email: It set input must be a valid email address.
unique: It checks for unique value against a database column.
numeric: Input value must numeric.
same:- It validates two input fields value must be same.

Laravel 8 Form Validation Example

In this step by step tutorial I’ll demonstrate you how to implement validations in laravel 8 form. Please follow the instruction given below:

Install Laravel 8

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

composer create-project --prefer-dist laravel/laravel larablog

1	composer create-project --prefer-dist laravel/laravel larablog

Configure Database In .env file

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=larablog
DB_USERNAME=root
DB_PASSWORD=

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=larablog

DB_USERNAME=root

DB_PASSWORD=

Create Routes:

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\HomeController;
Route::get('user/create', [ HomeController::class, 'create' ]);
Route::post('user/create', [ HomeController::class, 'store' ]);

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\HomeController;

Route::get('user/create', [ HomeController::class, 'create' ]);

Route::post('user/create', [ HomeController::class, 'store' ]);

Create Controller:

Next, we have to create a controller to display form and to handle form validation and submit operations. Lets Create a controller named HomeController using command given below –

php artisan make:controller <strong><span class="heads">HomeController</span></strong>

1	php artisan make:controller <strong><span class="heads">HomeController</span></strong>

Open the HomeController.php file and put the following code in it.

app/Http/Controllers/HomeController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\User;
  
class HomeController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('createUser');
    }
    
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $validatedData = $request->validate([
                'name' => 'required',
                'password' => 'required|min:5',
                'email' => 'required|email|unique:users'
            ], [
                'name.required' => 'Name is required',
                'password.required' => 'Password is required'
            ]);
  
        $validatedData['password'] = bcrypt($validatedData['password']);
        $user = User::create($validatedData);
      
        return back()->with('success', 'User created successfully.');
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\User;

class HomeController extends Controller

{

/**

* Show the application dashboard.

* @return \Illuminate\Http\Response

public function create()

{

return view('createUser');

}

/**

* Show the application dashboard.

* @return \Illuminate\Http\Response

public function store(Request $request)

{

$validatedData = $request->validate([

'name' => 'required',

'password' => 'required|min:5',

'email' => 'required|email|unique:users'

], [

'name.required' => 'Name is required',

'password.required' => 'Password is required'

]);

$validatedData['password'] = bcrypt($validatedData['password']);

$user = User::create($validatedData);

return back()->with('success', 'User created successfully.');

}

Create Blade File:

Now, create form blade view file to display form and submit to database. So, Go to resources/views and create createUser.blade.php and update the following code into it:

resources/views/createUser.blade.php

Laravel 8 Multiple Image Upload Tutorial

In this Laravel 8 Multiple Image Upload Tutorial, I’ll show you how to upload multiple image in laravel 8. In this laravel 8 multiple image upload example, I’ll show you how to validate upload image into folder and then save it into database. In this tutorial before saving image into database we will show preview of the images and then save it into directory. After successfully image upload into the database and folder we will display success message on the screen.

Laravel 8 Multiple Image Upload Tutorial

In this step by step Laravel 8 Multiple Image Upload Tutorial I will demonstrate you with example to upload multiple images in laravel 8. Please follow the instruction given below:

Step 1: Download Laravel 8

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

composer create-project --prefer-dist laravel/laravel blog

1	composer create-project --prefer-dist laravel/laravel blog

Setup Database Credentials

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=lara8blog
DB_USERNAME=root
DB_PASSWORD=

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=lara8blog

DB_USERNAME=root

DB_PASSWORD=

Add Migration and Model

Now, in this step we will create model and migration file. Please run the following command:

php artisan make:migration create_files_table

1	php artisan make:migration create_files_table

Once above command is executed there will be a migration file created inside database/migrations/ directory, just open migration file and update the function up() method as following:

<?php
  
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
  
class CreateFilesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('files', function (Blueprint $table) {
            $table->id();
            $table->string('filenames');
            $table->timestamps();
        });
    }
  
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('files');
    }
}

<?php

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

class CreateFilesTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('files', function (Blueprint $table) {

$table->id();

$table->string('filenames');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('files');

}

php artisan migrate

1	php artisan migrate

Now, in this step we will create model file. Please run the following command:

php artisan make:model File

1	php artisan make:model File

app/Models/File.php

<?php
  
namespace App\Models;
  
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
  
class File extends Model
{
    use HasFactory;
  
    protected $fillable = [
        'filenames'
    ];
  
    /**
     * Set the user's first name.
     *
     * @param  string  $value
     * @return void
     */
    public function setFilenamesAttribute($value)
    {
        $this->attributes['filenames'] = json_encode($value);
    }
}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class File extends Model

{

use HasFactory;

protected $fillable = [

'filenames'

];

/**

* Set the user's first name.

* @param string $value

* @return void

public function setFilenamesAttribute($value)

{

$this->attributes['filenames'] = json_encode($value);

}

Step 3: Create Routes

we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\FileController;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::get('file', [FileController::class, 'create']); 
Route::post('file', [FileController::class, 'store']);

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\FileController;

|--------------------------------------------------------------------------

| Web Routes

|--------------------------------------------------------------------------

| Here is where you can register web routes for your application. These

| routes are loaded by the RouteServiceProvider within a group which

| contains the "web" middleware group. Now create something great!

Route::get('file', [FileController::class, 'create']);

Route::post('file', [FileController::class, 'store']);

Step 4: Create Controller

Now, lets create a controller named FileController using command given below –

php artisan make:controller <span class="heads">FileController</span>

1	php artisan make:controller <span class="heads">FileController</span>

app/Http/Controllers/FileController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\File;
  
class FileController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('create');
    }
  
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $this->validate($request, [
                'filenames' => 'required',
                'filenames.*' => 'image'
        ]);
  
        $files = [];
        if($request->hasfile('filenames'))
         {
            foreach($request->file('filenames') as $file)
            {
                $name = time().rand(1,100).'.'.$file->extension();
                $file->move(public_path('files'), $name);  
                $files[] = $name;  
            }
         }
  
         $file= new File();
         $file->filenames = $files;
         $file->save();
  
        return back()->with('success', 'Data Your files has been successfully added');
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\File;

class FileController extends Controller

{

/**

* Show the application dashboard.

* @return \Illuminate\Http\Response

public function create()

{

return view('create');

}

/**

* Show the application dashboard.

* @return \Illuminate\Http\Response

public function store(Request $request)

{

$this->validate($request, [

'filenames' => 'required',

'filenames.*' => 'image'

]);

$files = [];

if($request->hasfile('filenames'))

{

foreach($request->file('filenames') as $file)

{

$name = time().rand(1,100).'.'.$file->extension();

$file->move(public_path('files'), $name);

$files[] = $name;

}

$file= new File();

$file->filenames = $files;

$file->save();

return back()->with('success', 'Data Your files has been successfully added');

}

Image Store in Storage Folder.

$file->storeAs('images', $imageName);

// storage/app/files/file.png

$file->storeAs('images', $imageName);

// storage/app/files/file.png

Image in Public Folder

$file->move(public_path('images'), $imageName);
// public/files/file.png

1 2	$file->move(public_path('images'), $imageName); // public/files/file.png

Storing Image in S3

$file->storeAs('images', $imageName, 's3');

1	$file->storeAs('images', $imageName, 's3');

Step 5: Create Blade File

In this step, we will create view/blade file. Lets create a blade file “create.blade.php” in “resources/views/” directory and put the following code in it respectively.

resources/views/create.blade.php

<html lang="en">
<head>

      $("body").on("click",".btn-danger",function(){

      });
    });

Laravel 8 Create Custom Helper Functions Tutorial

In this Laravel 8 Create Custom Helper Functions Tutorial I will show you how to create custom helper functions in laravel 8 application. In this tutorial you will learn to create custom helper file in laravel 8. With custom helper file you can define functions that you can reuse in your laravel application.

Laravel 8 Create Custom Helper Functions Tutorial

In this step by step tutorial you will learn to Create Custom Helper Functions in laravel. Please follow the instruction given below:

Step 1: Create helpers.php File

In custom helper file you can define your own functions and call anywhere in your laravel project. Go to App directory and create a new file helpers.php like this app/helpers.php.

app/helpers.php

<?php
function changeDateFormate($date,$date_format){
    return \Carbon\Carbon::createFromFormat('Y-m-d', $date)->format($date_format);    
}
function productImagePath($image_name)
{
    return public_path('images/products/'.$image_name);
}

<?php

function changeDateFormate($date,$date_format){

return \Carbon\Carbon::createFromFormat('Y-m-d', $date)->format($date_format);

}

function productImagePath($image_name)

{

return public_path('images/products/'.$image_name);

}

Step 2: Add File Path In composer.json File

In this step, we will add helper file path in composer.json file. Go to root directory and open composer.json file and put the following code into the file:

composer.json

...
"autoload": {

    "psr-4": {

        "App\\": "app/",

        "Database\\Factories\\": "database/factories/",

        "Database\\Seeders\\": "database/seeders/"
    },

    "files": [

        "app/helpers.php"
    ]
},
...

...

"autoload": {

"psr-4": {

"App\\": "app/",

"Database\\Factories\\": "database/factories/",

"Database\\Seeders\\": "database/seeders/"

"files": [

"app/helpers.php"

]

...

Step 3: Run Command

composer dump-autoload

1	composer dump-autoload

here we use custom helper functions like changeDateFormate() and productImagePath(), here we give you example how to use custom helper functions:

Use Custom Helper function In Route:

In this example we will using custom helper function in route:

Example:-

Route::get('helper', function(){
    $imageName = 'example.png';

    $fullpath = productImagePath($imageName);

    dd($fullpath);

});
 
Route::get('helper2', function(){

    $newDateFormat = changeDateFormate(date('Y-m-d'),'m/d/Y')

    dd($newDateFormat);

});

Route::get('helper', function(){

$imageName = 'example.png';

$fullpath = productImagePath($imageName);

dd($fullpath);

});

Route::get('helper2', function(){

$newDateFormat = changeDateFormate(date('Y-m-d'),'m/d/Y')

dd($newDateFormat);

});

Output:

"/var/www/me/laravel8/blog/public/images/products/example.png"

1	"/var/www/me/laravel8/blog/public/images/products/example.png"

"09/14/2020"

1	"09/14/2020"

Use Custom Helper function In Blade File:

In this example we will be using custom helper function in blade file:

$imageName = 'example.png';

$fullpath = productImagePath($imageName);

print_r($fullpath);

$imageName = 'example.png';

$fullpath = productImagePath($imageName);

print_r($fullpath);

{{ changeDateFormate(date('Y-m-d'),'m/d/Y')  }}

1	{{ changeDateFormate(date('Y-m-d'),'m/d/Y') }}
