Cookie Helper

Provides methods for working with COOKIE data.

Default settings for cookies are specified in application/config/cookie.php. You may override these settings by passing parameters to the helper.

1. domain: A valid domain, for which the cookie may be written. Default is '' (Use on localhost). For site-wide cookies, prefix your domain with a period .example.com
2. path: A valid path for which the cookie may be written. Default is the root directory '/'
3. expire: The cookie lifetime. Set the number of seconds the cookie should persist, until expired by the browser, starting from when the cookie is set. Note: Set to 0 (zero) seconds for a cookie which expires when the browser is closed. NOTE: time() will be added to this value, so be careful not to make expire too large.
4. secure: The cookie will only be allowed over a secure transfer protocol (HTTPS). Default is FALSE.
5. httponly: The cookie can be accessed via HTTP only, and not via client scripts. Default is FALSE. Note: Requires at least PHP version 5.2.0

cookie::set() accepts multiple parameters, only the cookie name and value are required. You may pass parameters to this method as discrete values:

cookie::set($name, $value, $expire, $path, $domain, $secure, $httponly);

Or you may pass an associative array of values as a parameter:

$cookie_params = array(
               'name'   => 'Very_Important_Cookie',
               'value'  => 'Choclate Flavoured Mint Delight',
               'expire' => '86500',
               'domain' => '.example.com',
               'path'   => '/'
               );
cookie::set($cookie_params);

cookie::get() accepts multiple parameters, Only the cookie name is required.

$cookie_value = cookie::get($cookie_name, $default_value = NULL, $xss_clean = FALSE);

Setting the third parameter to TRUE will filter the cookie for unsafe data.

Returns $default_value if the cookie item does not exist.

cookie::delete() accepts multiple parameters, Only the cookie name is required. This method is identical cookie::set() but sets the cookie value to '' effectively deleting it.

cookie::delete('stale_cookie');
