Cookie Helper

The Cookie Helper provides a set of functions to simplify working with browser cookies in LavaLust. It allows you to set, retrieve, and delete cookies through a simple API.

Note

This helper uses the framework’s internal IO class through lava_instance()->io. Make sure the IO class is properly loaded by the framework (it is loaded automatically in normal operation).

Function Summary

Function	Description
set_cookie()	Sets a new cookie with optional parameters.
get_cookie()	Retrieves a cookie value from the browser.
delete_cookie()	Deletes an existing cookie from the browser.

Available Functions

set_cookie($name, $value = '', $expiration = 0, $options = array())

Sets a cookie in the user’s browser.

Parameters:

• $name (string) – The cookie name.

• $value (string) – The cookie value (default: empty string).

• $expiration (int) – Cookie expiration time in seconds (default: 0, meaning “until the browser is closed”).

• $options (array) – Optional array of additional cookie settings such as domain, path, secure, and httponly.

Returns:

void

Example:

<?php
set_cookie('username', 'ronald', 3600, [
    'path'     => '/',
    'secure'   => true,
    'httponly' => true
])

get_cookie($name)

Fetches an item from the $_COOKIE array.

Parameters:

• $name (string) – The name of the cookie to retrieve.

Returns:

mixed — The cookie value if it exists, or null if it does not.

Example:

<?php
$username = get_cookie('username');
if ($username !== null) {
    echo "Welcome back, $username!";
}

delete_cookie($name, $domain = '', $path = '/', $prefix = '')

Deletes a cookie from the browser.

Parameters:

• $name (string) – The name of the cookie to delete.

• $domain (string) – The domain of the cookie (optional).

• $path (string) – The path of the cookie (default: '/').

• $prefix (string) – An optional cookie prefix.

Returns:

void

Example:

<?php
delete_cookie('username');

Additional Notes

• If your app uses a cookie prefix (set via the cookie_prefix config item), get_cookie() will attempt to resolve it automatically.

• The helper functions are simple wrappers around lava_instance()->io->set_cookie() and lava_instance()->io->cookie() for convenience.
