Laravel 11 Ajax Form Submit With Validation

Hello developers! In this guide, we'll see the laravel 11 Ajax form submitted with validation.

Here, we'll learn about how to submit forms with Ajax and perform validation in Laravel 11. We'll submit a form without page refresh using jQuery Ajax.

In this article, we'll create a form and it will open when click on the Create button then send an Ajax form request, and validate the form data into the controller.

So, let's see AJAX form validation in laravel 11.

Step 1: Installing Laravel 11 Application

Step 2: Create Migration and Model

Step 3: Create a Controller

Step 4: Create a Routes

Step 5: Create Blade File

Step 6: Run the Laravel 11 App

Step 1: Installing Laravel 11 Application

In this step, we'll install the laravel 11 application using the following command.

composer create-project laravel/laravel laravel-11-ajax-form

Step 2: Create Migration and Model

Then, we'll create a migration using the following command.

php artisan make:migration create_posts_table

Migration

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up(): void()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->text('body');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down(): void
    {
        Schema::dropIfExists('posts');
    }
};

Next, we'll migrate the migration into the database using the following command.

php artisan migrate

Now, we'll create a Post.php model using the following command.

php artisan make:model Post

app/Models/Post.php

<?php

namespace App\Models;

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

class Post extends Model
{
    use HasFactory;

    /**
     * Write code on Method
     *
     * @return response()
     */
    protected $fillable = [
        'title', 'body'
    ];
}

Step 3: Create a Controller

Then, we'll create a new PostController.php using the following command.

php artisan make:controller PostController

app/Http/Controllers/PostController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
use App\Models\Post;
use Illuminate\View\View;
use Illuminate\Http\JsonResponse;

class PostController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(): View
    {
        $posts = Post::get();

        return view('posts', compact('posts'));
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function store(Request $request): JsonResponse
    {
        $request->validate([
            'title' => 'required',
            'body' => 'required',
        ]);

        Post::create([
            'title' => $request->title,
            'body' => $request->body,
        ]);

        return response()->json(['success' => 'Post created successfully.']);
    }
}

Step 4: Create Routes

Then, we'll define the routes in the web.php file.

routes/web.php

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\PostController;

Route::get('posts', [ PostController::class, 'index' ]);
Route::post('posts', [ PostController::class, 'store' ])->name('posts.store');

Step 5: Create Blade File

Now, we'll create a posts.blade.php file. In this file, we'll create a form and send an AJAX jQuery request.

resources/views/posts.blade.php
