CodeIgniter - Cookie Management

Cookie is a small piece of data sent from web server to store on client’s computer. CodeIgniter has one helper called “Cookie Helper” for cookie management.
Syntax
set_cookie($name[, $value = ''[, $expire = ''[, $domain = ''[, $path = '/'[, $prefix = ''[, $secure = FALSE[, $httponly = FALSE]]]]]]]])
Parameters
  • $name (mixed) − Cookie name or associative array of all of the parameters available to this function
  • $value (string) − Cookie value
  • $expire (int) − Number of seconds until expiration
  • $domain (string) − Cookie domain (usually: .yourdomain.com)
  • $path (string) − Cookie path
  • $prefix (string) − Cookie name prefix
  • $secure (bool) − Whether to only send the cookie through HTTPS
  • $httponly (bool) − Whether to hide the cookie from JavaScript
Return Type
void
In the set_cookie() function, we can pass all the values using two ways. In the first way, only array can be passed and in the second way, individual parameters can also be passed.
Syntax
get_cookie($index[, $xss_clean = NULL]])
Parameters
  • $index (string) − Cookie name
  • $xss_clean (bool) − Whether to apply XSS filtering to the returned value
Return
The cookie value or NULL if not found
Return Type
mixed
The get_cookie() function is used to get the cookie that has been set using the set_cookie() function.
Syntax
delete_cookie($name[, $domain = ''[, $path = '/'[, $prefix = '']]]])
Parameters
  • $name (string) − Cookie name
  • $domain (string) − Cookie domain (usually: .yourdomain.com)
  • $path (string) − Cookie path
  • $prefix (string) − Cookie name prefix
Return Type
void
The delete_cookie() function is used to delete the cookie().

Example

Create a controller called Cookie_controller.php and save it at application/controller/Cookie_controller.php
<?php 
class Cookie_controller extends CI_Controller {

function __construct() {
parent
::__construct();
$this
->load->helper(array('cookie', 'url'));
}

public function index() {
set_cookie
('cookie_name','cookie_value','3600');
$this
->load->view('Cookie_view');
}

public function display_cookie() {
echo get_cookie
('cookie_name');
$this
->load->view('Cookie_view');
}

public function deletecookie() {
delete_cookie
('cookie_name');
redirect
('cookie/display');
}

}
?>
Create a view file called Cookie_view.php and save it at application/views/Cookie_view.php
<!DOCTYPE html> 
<html lang = "en">

<head>
<meta charset = "utf-8">
<title>CodeIgniter View Example</title>
</head>

<body>
<a href = 'display'>Click Here</a> to view the cookie.<br>
<a href = 'delete'>Click Here</a> to delete the cookie.
</body>

</html>
Change the routes.php file in application/config/routes.php to add route for the above controller and add the following line at the end of the file.
$route['cookie'] = "Cookie_controller"; 
$route
['cookie/display'] = "Cookie_controller/display_cookie";
$route
['cookie/delete'] = "Cookie_controller/deletecookie";
After that, you can execute the following URL in the browser to execute the example.
http://yoursite.com/index.php/cookie
It will produce an output as shown in the following screenshot.
