CREATE TABLE IF NOT EXISTS `users` ( `id` int(11) NOT NULL AUTO_INCREMENT, `first_name` varchar(64) NOT NULL, `last_name` varchar(64) NOT NULL, `address` text NOT NULL, `email` varchar(64) NOT NULL, `mobile` varchar(12) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=15 ; |
Connect to Database
Go to the config folder and open database.php file some changes in this file like hostname, database username, database password, and database name.

$db['default'] = array( 'dsn' => '', 'hostname' => 'localhost', 'username' => 'root', 'password' => '', 'database' => 'enter here database name', 'dbdriver' => 'mysqli', 'dbprefix' => '', 'pconnect' => FALSE, 'db_debug' => (ENVIRONMENT !== 'production'), 'cache_on' => FALSE, 'cachedir' => '', 'char_set' => 'utf8', 'dbcollat' => 'utf8_general_ci', 'swap_pre' => '', 'encrypt' => FALSE, 'compress' => FALSE, 'stricton' => FALSE, 'failover' => array(), 'save_queries' => TRUE ); |
Create Controller
In this step, we will create a Ci_autocomplete.php file in the “application/controller” directory and paste the below code in this controller.
application/controller/Ci_autocomplete.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
<?php defined('BASEPATH') OR exit('No direct script access allowed'); class Ci_autocomplete extends CI_Controller { /** * Constructor of Controller * * @return Response */ public function __construct() { parent::__construct(); $this->load->database(); } public function index() { $this->load->view('autocomplete'); } public function search() { $query = $this->input->get('query'); $this->db->like('first_name', $query); $data_result = $this->db->get("users")->result(); $data = array(); foreach ($data_result as $row) { $data[] = $row->first_name; } echo json_encode($data); } } ?> |
Create View File
So finally, we will create the autocomplete.php file in the “application/views/” directory.
application/views/autocomplete.php
