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
|
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.
|
1 2 3 4 5 6 |
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
|
1 2 3 4 5 |
<?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 –
|
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
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 |
<?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
