Cookie Helper
#############
The Cookie Helper file contains functions that assist in working with
cookies.
.. contents::
:local:
.. raw:: html
<div class="custom-index container"></div>
Loading this Helper
===================
This helper is loaded using the following code::
$this->load->helper('cookie');
Available Functions
===================
The following functions are available:
.. php:function:: set_cookie($name[, $value = ''[, $expire = 0[, $domain = ''[, $path = '/'[, $prefix = ''[, $secure = NULL[, $httponly = NULL]]]]]]])
:param mixed $name: Cookie name *or* associative array of all of the parameters available to this function
:param string $value: Cookie value
:param int $expire: Number of seconds until expiration
:param string $domain: Cookie domain (usually: .yourdomain.com)
:param string $path: Cookie path
:param string $prefix: Cookie name prefix
:param bool $secure: Whether to only send the cookie through HTTPS
:param bool $httponly: Whether to hide the cookie from JavaScript
:rtype: void
This helper function gives you friendlier syntax to set browser
cookies. Refer to the :doc:`Input Library <../libraries/input>` for
a description of its use, as this function is an alias for
``CI_Input::set_cookie()``.
.. php:function:: get_cookie($index[, $xss_clean = FALSE])
:param string $index: Cookie name
:param bool $xss_clean: Whether to apply XSS filtering to the returned value
:returns: The cookie value or NULL if not found
:rtype: mixed
This helper function gives you friendlier syntax to get browser
cookies. Refer to the :doc:`Input Library <../libraries/input>` for
detailed description of its use, as this function acts very
similarly to ``CI_Input::cookie()``, except it will also prepend
the ``$config['cookie_prefix']`` that you might've set in your
*application/config/config.php* file.
.. php:function:: delete_cookie($name[, $domain = ''[, $path = '/'[, $prefix = '']]])
:param string $name: Cookie name
:param string $domain: Cookie domain (usually: .yourdomain.com)
:param string $path: Cookie path
:param string $prefix: Cookie name prefix
:rtype: void
Lets you delete a cookie. Unless you've set a custom path or other
values, only the name of the cookie is needed.
::
delete_cookie('name');
This function is otherwise identical to ``set_cookie()``, except that it
does not have the value and expiration parameters. You can submit an
array of values in the first parameter or you can set discrete
parameters.
::
delete_cookie($name, $domain, $path, $prefix);
