Today we are going to use Ajax to create a simple jQuery Live Search in Code Igniter:

  • Step 1 – Create the data controller/view
  • Step 2 – Create the web page controller/view

Include jQuery

Please note that we will be using the jQuery library, so you need to include it in your <head> section. You can do this by adding the following <script> line to your templates/header.php file:

<html>
<head>
   <title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
   <script src="http://code.jquery.com/jquery-2.1.0.min.js"></script>
</head>
<body>
	<h1>CodeIgniter 2 Tutorial</h1>

Step 1 – Create the data controller/view

First we need to create the page (i.e. model + controller + view) that will return the Ajax data.

<?php
class Ajax extends CI_Controller 
{

   public function getdata($param = '')
   {
      // Get data from db
      $data['ajaxdata'] = "Search result for $param";
  
      // Pass data to view
      $this->load->view('ajax/index', $data);
   }
}

Step 2 – Create the web page controller/view
