Hi, Dev
In this guide, I'll walk you through implementing Select2 AJAX autocomplete search functionality within a Laravel 11 application.
Firstly, let's start by setting up a new Laravel 11 project and executing migrations to create the necessary 'users' table. Following that, we'll populate this table with some sample data using Laravel's Tinker.
Next, we'll craft a straightforward Blade view containing an input field for search purposes. Utilizing Select2 JavaScript library, we'll enhance this input field to feature autocomplete capabilities facilitated by AJAX requests.
Step for Laravel 11 Dynamic Autocomplete Search with Select2 Example
Step 1: Install Laravel 11
Step 2: Add Dummy Users
Step 3: Create Controller
Step 4: Create Routes
Step 5: Create View File
Run Laravel App
So, let's see the simple steps to complete this task.
Step 1: Install Laravel 11
This step is not required; however, if you have not created the Laravel app, then you may go ahead and execute the below command:
composer create-project laravel/laravel 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

$('#search').select2({
placeholder: 'Select an user',
ajax: {
url: path,
dataType: 'json',
delay: 250,
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
id: item.id
}
})
};
},
cache: true
}
});
</script>
