Laravel 5 - Autocomplete Mutiple Fields Using jQuery, Ajax and MySQL

In this Laravel PHP Tutorial, You will learn the process of adding multiple fields with autocomplete functionality using jQuery, Ajax, Laravel and Database(MySQL).

In this example, I am going to search country using autocomplete functionality and while selecting country name from search list, the other fields will populate corresponding to search type.

Step 1: Create Sample Table

In first step, I will create sample table "countries" to test this code.

CREATE TABLE `countries` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `sortname` varchar(3) NOT NULL,
 `name` varchar(150) NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=247 DEFAULT CHARSET=utf8
Step 2: Add routes

In this step, I will add following two routes :

routes/web.php
  1. Route::get('autocomplete', 'AjaxAutocompleteController@index');
  2. Route::get('searchajax', ['as'=>'searchajax','uses'=>'AjaxAutocompleteController@searchResponse']);

Using first route, We will display a form to user to search country and get the response from second routes.

Step 3: Create Controller

In this step, I will create AjaxAutocompleteController.php in following path app/Http/Controllers.

app/Http/Controllers/AjaxAutocompleteController.php
  1. <?php
  2. namespace App\Http\Controllers;
  3. use Illuminate\Http\Request;
  4. class AjaxAutocompleteController extends Controller
  5. {
  6.     public function index(){        
  7.         return view('autocomplete');
  8.     }
  9.     public function searchResponse(Request $request){
  10.         $query = $request->get('term','');
  11. $countries=\DB::table('countries');
  12. if($request->type=='countryname'){
  13.     $countries->where('name','LIKE','%'.$query.'%');
  14. }
  15. if($request->type=='country_code'){
  16.             $countries->where('sortname','LIKE','%'.$query.'%');
  17. }
  18.     $countries=$countries->get();
  19. $data=array();
  20. foreach ($countries as $country) {
  21. $data[]=array('name'=>$country->name,'sortname'=>$country->sortname);
  22. }
  23. if(count($data))
  24. return $data;
  25. else
  26. return ['name'=>'','sortname'=>''];
  27.     }
  28. }
Step 4: Create View File

Now i will create a file autocomplete.blade.php in following path resources/views/.

  1. <!DOCTYPE html>
  2. <html>
  3. <head>
  4.     <title>Laravel 5 - Autocomplete Mutiple Fields Using jQuery, Ajax and MySQL</title>

  46. $('table').append(data);
  47. i++;
  48. });
  49. function select_all() {
  50. $('input[class=chkbox]:checkbox').each(function(){

  70. $(this).autocomplete({
