In this example, we will download the fresh Laravel 12 app and run migration for creating the users table. Then we will create some dummy users using Tinker. Then we will create a simple Blade file with the search input field. We will create an autocomplete textbox using Select2 JS with an AJAX request.

Laravel 12 Select2 Ajax Autocomplete Search Example

Install Laravel 12

This step is not required; however, if you have not created the Laravel app, then you may go ahead and execute the below command:

laravel new example-app

Step 2: Add Dummy Users

After creating the users table, we will create some dummy users using the Tinker factory. So let’s create dummy records using the below command:

php artisan tinker
    
User::factory()->count(20)->create()

Step 3: Create Controller

At this point, we should create a new controller named SearchController. This controller will include two methods: one to return a view response and another to handle AJAX requests with JSON responses. Place the following content in the controller file:

app/Http/Controllers/SearchController.php

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\View\View;
use Illuminate\Http\JsonResponse;
 
class SearchController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(): View
    {
        return view('searchDemo');
    }
       
    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function autocomplete(Request $request): JsonResponse
    {
        $data = [];
     
        if($request->filled('q')){
            $data = User::select("name", "id")
                        ->where('name', 'LIKE', '%'. $request->get('q'). '%')
                        ->take(10)
                        ->get();
        }
      
        return response()->json($data);
    }
}

Step 4: Create Routes

In this step, we need to create a route for the datatables layout file and another one for getting data. So open your “routes/web.php” file and add the following route.

routes/web.php

<?php
   
use Illuminate\Support\Facades\Route;
   
use App\Http\Controllers\SearchController;
    
Route::get('demo-search', [SearchController::class, 'index']);
Route::get('autocomplete', [SearchController::class, 'autocomplete'])->name('autocomplete');

Step 5: Create View File

In the last step, let’s create `searchDemo.blade.php` (`resources/views/searchDemo.blade.php`) for layout and list all items code here and put the following code:

resources/views/searchDemo.blade.php

              results:  $.map(data, function (item) {
                    return {
                        text: item.name,
                        id: item.id
