Manual Laravel Autocomplete search from Database

Sometime we need autocomplete searchable text box which is reflect from database and we use third party plugins.Now I am going to tell you how to create manually autocomplete search text box in Laravel 5.2.

There should be installed Laravel 5.2 in your system if Laravel is not installed then install Laravel with following command.

composer create-project --prefer-dist laravel/laravel blog

Create a Products Table and Model

Follow below url till product table creation process or you can create `Products` table in your database and relatively create model in following path app/Product.php with name `Product`.

Laravel 5.2 CRUD (Create Read Update Delete) Example from Scratch

Insert some test data in your product table or you can use Laravel seed classes to seeding your database with test data.If you want to write seeders then run this command that generate seed file in database/seeds directory.

php artisan make:seeder UsersTableSeeder

Now let's start to creating autocomplete search text box.

Add Route and Controller

Add these two routes in your routes.php file.

app/Http/routes.php

Route::get('autocomplete',array('as'=>'autocomplete','uses'=>'AutoCompleteController@index'));
Route::get('searchajax',array('as'=>'searchajax','uses'=>'AutoCompleteController@autoComplete'));

Route::get('autocomplete',array('as'=>'autocomplete','uses'=>'AutoCompleteController@index'));Route::get('searchajax',array('as'=>'searchajax','uses'=>'AutoCompleteController@autoComplete'));

Now we will create AutoCompleteController.php in following path app/Http/Controllers

app/Http/Controllers/AutoCompleteController.php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Product;
class AutoCompleteController extends Controller {
    
    public function index(){
        return view('autocomplete.index');
   }
    public function autoComplete(Request $request) {
        $query = $request->get('term','');
        
        $products=Product::where('name','LIKE','%'.$query.'%')->get();
        
        $data=array();
        foreach ($products as $product) {
                $data[]=array('value'=>$product->name,'id'=>$product->id);
        }
        if(count($data))
             return $data;
        else
            return ['value'=>'No Result Found','id'=>''];
    }
    
}

namespace App\Http\Controllers;use Illuminate\Http\Request;use App\Http\Controllers\Controller;use App\Product;class AutoCompleteController extends Controller {	    public function index(){        return view('autocomplete.index');    }	public function autoComplete(Request $request) {        $query = $request->get('term','');		        $products=Product::where('name','LIKE','%'.$query.'%')->get();                $data=array();        foreach ($products as $product) {                $data[]=array('value'=>$product->name,'id'=>$product->id);        }        if(count($data))             return $data;        else            return ['value'=>'No Result Found','id'=>''];    }	}

Create Blade File

Now we will create index.blade.php file in following resources/views/autocomplete/ directory.

@extends('layouts.default')
 
@section('content')
   <div class="row">
        <div class="col-xs-12 col-sm-12 col-md-12">
            <div class="form-group">
                
                {!! Form::text('search_text', null, array('placeholder' => 'Search Text','class' => 'form-control','id'=>'search_text')) !!}
            </div>
        </div>
    </div>
    
   <script>
   $(document).ready(function() {
    src = "{{ route('searchajax') }}";
     $("#search_text").autocomplete({
        source: function(request, response) {
            $.ajax({
                url: src,
                dataType: "json",
                data: {
                    term : request.term
                },
                success: function(data) {
                    response(data);
                   
                }
            });
        },
        minLength: 3,
       
    });
});
</script>
@endsection

@extends('layouts.default') @section('content')   <div class="row">        <div class="col-xs-12 col-sm-12 col-md-12">            <div class="form-group">                                {!! Form::text('search_text', null, array('placeholder' => 'Search Text','class' => 'form-control','id'=>'search_text')) !!}            </div>        </div>    </div>       <script> $(document).ready(function() {    src = "{{ route('searchajax') }}";    $("#search_text").autocomplete({        source: function(request, response) {            $.ajax({                url: src,                dataType: "json",                data: {                    term : request.term                },                success: function(data) {                    response(data);                                   }            });        },        minLength: 3,           });});</script>@endsection

Don't forget to add Js and Css file in your master/default layout.
