CI_Input::set_cookie()

set_cookie($name = ''[, $value = ''[, $expire = ''[, $domain = ''[, $path = '/'[, $prefix = ''[, $secure = FALSE[, $httponly = FALSE]]]]]]])

Sets a cookie containing the values you specify. There are two ways to pass information to this method so that a cookie can be set: Array Method, and Discrete Parameters:

Array Method

Using this method, an associative array is passed to the first parameter:

$cookie = array(
        'name'   => 'The Cookie Name',
        'value'  => 'The Value',
        'expire' => '86500',
        'domain' => '.some-domain.com',
        'path'   => '/',
        'prefix' => 'myprefix_',
        'secure' => TRUE
);

$this->input->set_cookie($cookie);

Notes

Only the name and value are required. To delete a cookie set it with the expiration blank.

The expiration is set in seconds, which will be added to the current time. Do not include the time, but rather only the number of seconds from now that you wish the cookie to be valid. If the expiration is set to zero the cookie will only last as long as the browser is open.

For site-wide cookies regardless of how your site is requested, add your URL to the domain starting with a period, like this: .your-domain.com

The path is usually not needed since the method sets a root path.

The prefix is only needed if you need to avoid name collisions with other identically named cookies for your server.

The secure boolean is only needed if you want to make it a secure cookie by setting it to TRUE.

Discrete Parameters

If you prefer, you can set the cookie by passing data using individual parameters:

$this->input->set_cookie($name, $value, $expire, $domain, $path, $prefix, $secure);
