Laravel 9 Autocomplete Search with Select2 JS Example

In this quick example, let’s see laravel 9 autocomplete search using select2 js. you’ll learn laravel 9 select2 autocomplete search. I explained simply step by step laravel 9 autocomplete input box using select2 js. I explained simply step by step laravel 9 autocomplete textbox box using select2 js.

In this example, we will download the fresh laravel 9 app and run migration for creating users table. Then we will create some dummy users using tinker. Then we will create a simple blade file with the input field. we will create autocomplete text box using Select2 JS js.

So, let’s see simple steps to complete this task.

Step 1: Install Laravel 9

This is optional; 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

First, we need to run default migrations, so we have created new users table. so let’s run migration command:

php artisan migrate

next, we will create some dummy users using tinker factory. so let’s create dummy records using bellow command:

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

Step 3: Create Controller

In this point, now we should create new controller as SearchController. This controller we will add two method, one for return view response and another for getting ajax with json response. return response, so put bellow content in controller file:

app/Http/Controllers/SearchController.php

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

Step 4: Create Routes

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

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\SearchController;
  
/* 
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::controller(SearchController::class)->group(function(){
    Route::get('demo-search', 'index');
    Route::get('autocomplete', 'autocomplete')->name('autocomplete');
});

Step 5: Create View File

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

resources/views/searchDemo.blade.php

          url: path,
          dataType: 'json',
          delay: 250,
          processResults: function (data) {

                    return {
                        text: item.name,
                        id: item.id
                    }
                })
            };
          },
          cache: true
