Laravel 8.0 Ajax Form Validation Example

Today we will make ajax form validation, so that we can make our form validation without refreshing web page. so, let’s start…

Create a Laravel new project, run this command
composer create-project --prefer-dist laravel/laravel blog
Make Database connection
Go to the .env file and set the database name that you create in your MySQL dashboard admin panel

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

Create our custom route

routes/web.php

Route::get('post/create', [PostController::class, 'postCreateByAjax'])
    ->name('post.validation');
Route::post('post/store', [PostController::class, 'postStoreByAjax'])
    ->name('post.validation.store');

Create Model
we will create Post model, run this command

php artisan make:model Post

Models/Post.php

<?php

namespace App\Models;

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

class Post extends Model
{
    use HasFactory;
    protected $fillable = [
        'title',
        'description'
    ];

}

Create Controller
we will create controller named PostController, run this command

php artisan make:controller PostController

app/Http/Controllers/PostController.php

<?php

namespace App\Http\Controllers;

use App\Models\Post;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class PostController extends Controller
{

    public function postCreateByAjax(){
        return view('ajax.ajax-create');
    }

    public function postStoreByAjax(Request $request){

        $validator = Validator::make($request->all(), [
            'title' => 'required',
            'description' => 'required',
        ]);

        if ($validator->passes()) {

            Post::create($request->all()); // it store data to the DB

            return response()->json(['success'=>'Added new records.']);

        }

        return response()->json(['error'=>$validator->errors()]);
