The purpose of this method is to safely redirect users to a given location, after checking if the location is valid and accessible.
||The location you wish to redirect to
The method takes two parameters: $location
, which is the URL or file path to redirect to, and $args
, which is a string of additional arguments to append to the URL, if any.
The method first sets some global variables such as $us_url_root
, and $user
, which are used to construct the redirect URL.
is not null, the method checks if debug mode is enabled in $settings
, and if so, logs a diagnostic message with information about the redirect using the logger function.
The method then checks if the $location
is a valid URL or file path by using the file_exists function and checking if it starts with 'http://' or 'https://'. If it is not a valid URL or file path, it tries different prefixes such as $us_url_root
, '../', 'users/', and so on, to see if the
file exists in any of these directories. If it finds a match, it updates $location
with the full path to the file.
is not empty, the method appends it to $location
to include any additional arguments in the URL.
If headers have not already been sent to the browser, the method uses the header function to send a Location header with the updated $location
, and exits the script using the exit function.
Overall, the "safe" method provides a robust way to safely redirect users to a given location, even if the file path or URL is not immediately accessible, and works around potential issues with headers already being sent.
