Hi Dev,
In this tutorial, I would like to share with you how to use form validation in laravel 8. I will let you know how to implement form input validation in laravel 8. In this tutorial, I will show you how to define laravel validation rules, how to validate form input and to display validation errors.
we will help you to give example of form validation with error message in laravel 8. In this blog, laravel 8 form validation example tutorial.
Here I will give you full example for laravel 8 form validation example. So let's follow bellow step by step.
Step 1 : Install Laravel 8
In the first step, we need to get fresh laravel 8 version application So let's open terminal and run bellow command to install fresh laravel project.
composer create-project --prefer-dist laravel/laravel blog
Step 2 : Database Configuration
In second step, we will make database Configuration for example database name, username, password etc for our crud application of laravel 8 So lets open .env file and fill all deatils like as bellow:
.env
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)
Step 3: Add Resource Route
Here, we need to add resource route for form validation in user create. so open your "routes/web.php" file and add following route.
routes/web.php
use App\Http\Controllers\HomeController;
Route::get('user/create', [ HomeController::class, 'create' ]);
Route::post('user/store', [ HomeController::class, 'store' ]);
Step 4: Add Controller
In this step, now we should create new controller as HomeController. So run bellow command and create new controller. bellow controller for create resource controller.
php artisan make:controller HomeController
After bellow command you will find new file in this path "app/Http/Controllers/HomeController.php".
In this controller will create seven methods by default as bellow methods:
1)create()
2)store()
So, let's copy bellow code and put on HomeController.php file.
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.');
}
}
Step 5: Add Blade Files
In last step. In this step we have to create just blade files. So mainly we have to create createUser file. So finally you have to create createUser bellow blade file:
So let's open createUser.blade.php following file and put bellow code.
resources/views/createUser.blade.php
resources/views/createUser.blade.php
