Today we will make ajax form validation so that we can make our form validation without a refreshing the web page. so, let’s start…
Our Final Output
Create a Laravel new project, run this command
composer create-project --prefer-dist laravel/laravel blogMake 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
<?phpnamespace 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 a controller named PostController, run this command
php artisan make:controller PostController
app/Http/Controllers/PostController.php
<?phpnamespace 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()]); }
}
Make Migration file
php artisan make:migration create_post_table –create=posts
database/migration/2020_09_20_163428_create_post_table.php
<?phpuse Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;class CreatePostTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('posts', function (Blueprint $table) {
$table->id();
$table->text('title');
$table->text('description');
$table->timestamps();
});
} /**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('posts');
}
}
