# Cookie Helper

The Cookie Helper file contains functions that assist in working with cookies.

## Loading this Helper

This helper is loaded using the following code:

`$this->load->helper('cookie');`

The following functions are available:

## set_cookie()

This helper function gives you view file friendly syntax to set browser cookies. Refer to the Input class for a description of use, as this function is an alias to $this->input->set_cookie().

## get_cookie()

This helper function gives you view file friendly syntax to get browser cookies. Refer to the Input class for a description of use, as this function is an alias to $this->input->cookie().

## delete_cookie()

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)`
