laravel 11 form validation example tutorial, show you how to add validation in Laravel along with Custom Error Messages, explained step by step. Laravel offers a robust validation mechanism with the flexibility to customize error messages. With Laravel, validating form input data and presenting clear error messages to users is straightforward thanks to its built-in form validation feature.

Laravel 11 Form Validation Example

You can validate your form and display messages in Laravel 11 application using the following steps:

First, you need to will create two routes one for showing form and another is displaying error messages in Laravel.

Step 1: Make Routes

use App\Http\Controllers\PostController;

Route::get('posts', 'PostController@create');
Route::post('posts', 'PostController@store')->name('posts');

Step 2: Create Controller

Now we will generate a new controller to handle the validation error messages request and showing them:

php artisan make:controller PostController

Now open your new generated controller App\Http\Controllers\PostController and put the below code on it:

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Post;
class PostController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('posts');
    }
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
           'title' => 'required|unique:posts|max:255',
           'discription' => 'required',
        ]);
        Post::create($request);
        return back()->with('success', 'Post created successfully.');
    }
}

Step 3: Create Blade File

Next, we need to create a posts.blade.php blade view file for showing the form.

Now open the resources/views/posts.blade.php file and put the below code on it.

<!DOCTYPE html>
<html>
<head>
    <title>Laravel form validation example - codingdriver.com</title>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link href="//netdna.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
    <div class="container">
        <h1>Laravel form validation Example</h1>
        @if(Session::has('success'))
        <div class="alert alert-success">
            {{ Session::get('success') }}
            @php
                Session::forget('success');
            @endphp
        </div>
        @endif
        <form method="POST" action="{{ route('posts') }}">
            {{ csrf_field() }}
            <div class="form-group">
                <label>Title:</label>
                <input type="text" name="title" class="form-control" placeholder="Name">
                @if ($errors->has('title'))
                    <span class="text-danger">{{ $errors->first('title') }}</span>
                @endif
            </div>
            <div class="form-group">
                <strong>Discription:</strong>
                <textarea name="discription" class="form-control" placeholder="Discription"><textarea>
                @if ($errors->has('discription'))
                    <span class="text-danger">{{ $errors->first('discription') }}</span>
                @endif
            </div>
            <div class="form-group">
                <button class="btn btn-success btn-submit">Submit</button>
            </div>
        </form>
    </div>
</body>
</html>

Now you can check the validations errors in laravel blade file.
