In this article, we will see the laravel 8 form validation example. form validation in laravel is a very common functionality and it is used in each and every website to validate the form field. Here, we will use has function in the session to check the error messages in laravel 8. using this example you can check simple form validation as well as you can create your own custom validation in laravel 8.
So, let's see the laravel custom validation rule example and laravel 8 form validation example.
We are adding a route in the web.php file for the form validation tutorial in laravel 8.
<?php
use Illuminate\Support\Facades\Route;
Route::get('user/create','App\Http\Controllers\[email protected]');
Route::post('user/store','App\Http\Controllers\[email protected]');Now, we will create UserController to save data in the database. So, add the below code to your controller.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
class UserController extends Controller
{
public function create()
{
return view('index');
}
public function store(Request $request)
{
$validatedData = $request->validate([
'name' => 'required',
'password' => 'required|min:8',
'email' => 'required|email|unique:users'
], [
'name.required' => 'Name is required',
'password.required' => 'Password is required',
'email.required' => 'Email is required'
]);
$validatedData['password'] = bcrypt($validatedData['password']);
$user = User::create($validatedData);
return back()->with('success', 'User Created Successfully !!');
}
}In this step, we will create a blade file and save the name as index.blade.php
