Laravel Bootstrap Typeahead Autocomplete Search from Database

Autocomplete make more flexible to get relevant data from database and i use different different type of autocomplete to search data from database.

I have already post article regarding manual autocomplete search from database but now i am going to use typeahead js to search data from database.

You can define custom template too in typeahead autocomplete search text box.

Here is a sample example to define template in searchable textbox if you are getting empty records from server api.

  1. $('#keyword').typeahead(null, {
  2. name: 'query',
  3. displayKey: 'value',
  4. source: autosuggest.ttAdapter(),
  5. templates: {
  6. empty: [
  7. '<div class="empty-message">',
  8. 'Unable to find any suggestion for your query',
  9. '</div>'
  10. ].join('\n'),
  11. suggestion: Handlebars.compile('<div>@{{value}}<br><span>@{{data}}</div>')
  12. }
  13. }).on('typeahead:selected', function (obj, datum) {
  14. window.location.href = datum.href;
  15. });

Now i am going to tell you step by step process to create typeahead autocomplete search box in Laravel.

Step 1: Create Products table and module

You should have a table with some demo data to text this code so first create a product table by creating migration file for products table using Laravel 5 php artisan comand.

php artisan make:migration create_products_table 

After this command you will get a migration file in following path database/migrations and now add below line of code in your migration file for create products table.

  1. use Illuminate\Database\Schema\Blueprint;
  2. use Illuminate\Database\Migrations\Migration;
  3. class CreateProductsTable extends Migration
  4. {
  5. public function up()
  6. {
  7. Schema::create('products', function (Blueprint $table) {
  8. $table->increments('id');
  9. $table->string('name');
  10. $table->text('details');
  11. $table->timestamps();
  12. });
  13. }
  14. public function down()
  15. {
  16. Schema::drop("products");
  17. }
  18. }

When you will run this command then you will find a table Products in your database.

Now you can feed demo data manually or you can use Laravel seed classes to seeding your database with test data.

Now create a Model for Product Table in following path app/Product.php

  1. namespace App;
  2. use Illuminate\Database\Eloquent\Model;
  3. class Product extends Model
  4. {
  5. public $fillable = ['name','details'];
  6. }
Step 2: Add Route and Controller functionality

Add two routes for getting view form and second routes to getting database json response.

app/Http/routes.php

  1. Route::get('typeahead-search',array('as'=>'typeahead.search','uses'=>'AutoCompleteController@sampleForm'));
  2. Route::get('typeahead-response',array('as'=>'typeahead.response','uses'=>'AutoCompleteController@typeahead'));

Now create a AutoCompleteController.php in following path app/Http/Controllers/AutoCompleteController.php add two functionality inAutoCompleteController Controller

  1. public function sampleForm(){
  2. return view('autocomplete');
  3. }
  4. public function typeahead(Request $request){
  5.     $query = $request->get('term','');        
  6. $products=Product::where('name','LIKE','%'.$query.'%')->get();     
  7. return response()->json($products);
  8. }
Step 3: Create View

Create a master layout as Laravel standard.

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="utf-8">
  5. <meta http-equiv="X-UA-Compatible" content="IE=edge">
  6. <meta name="viewport" content="width=device-width, initial-scale=1">
  7. <title>Laravel Bootstrap Typeahead Autocomplete Search from Database</title>
  8. <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">
  9. <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>
  10. <script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-3-typeahead/4.0.1/bootstrap3-typeahead.min.js"></script>
  11. </head>
  12. <body>
  13. <div class="container">
  14. @if ($message = Session::get('success'))
  15. <div class="alert alert-success">
  16. <p>{{ $message }}</p>
  17. </div>
  18. @endif
  19. @yield('content')
  20. </div>
  21. </body>
  22. </html>

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

resources/views/autocomplete.blade.php
  1. @extends('layouts.master')
  2. @section('content')
  3. <div class="row">
  4. <div class="col-xs-12 col-sm-12 col-md-6 col-md-offset-3">
  5. <div class="panel panel-primary">
  6. <div class="panel-heading">Example of Bootstrap Typeahead Autocomplete Search Textbox</div>
  7. <div class="panel-body">
  8. <div class="form-group">
  9. {!! Form::text('search_text', null, array('placeholder' => 'Search Text','class' => 'form-control','id'=>'search_text')) !!}
  10. </div>
  11. </div>
  12. </div>
  13. </div>
  14. </div>
  15. <script type="text/javascript">
  16. var url = "{{ route('typeahead.response') }}";
  17. $('#search_text').typeahead({
  18. source: function (query, process) {
  19. return $.get(url, { query: query }, function (data) {
  20. return process(data);
  21. });
  22. }
  23. });
  24. </script>
  25. @endsection
