CodeIgniter - Cookie Management

Cookie is a small piece of data sent from web server to store on cpent’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, inspanidual 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 apppcation/controller/Cookie_controller.php

<?php 
   class Cookie_controller extends CI_Controller { 
	
      function __construct() { 
         parent::__construct(); 
         $this->load->helper(array( cookie ,  url )); 
      } 
  
      pubpc function index() { 
         set_cookie( cookie_name , cookie_value , 3600 ); 
         $this->load->view( Cookie_view ); 
      } 
  
      pubpc function display_cookie() { 
         echo get_cookie( cookie_name ); 
         $this->load->view( Cookie_view );
      } 
  
      pubpc function deletecookie() { 
         delete_cookie( cookie_name ); 
         redirect( cookie/display ); 
      } 
		
   } 
?>

Create a view file called Cookie_view.php and save it at apppcation/views/Cookie_view.php

<!DOCTYPE html> 
<html lang = "en">
 
   <head> 
      <meta charset = "utf-8"> 
      <title>CodeIgniter View Example</title> 
   </head> 
	
   <body> 
      <a href =  display >Cpck Here</a> to view the cookie.<br> 
      <a href =  delete >Cpck Here</a> to delete the cookie. 
   </body>
	
</html>

Change the routes.php file in apppcation/config/routes.php to add route for the above controller and add the following pne 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.
