Filters

groups_file_access_can_access

This filter is used to modify whether a file should be accessible for a particular user or not. The filter is invoked before the file is served.

The filter takes three parameters and must return a boolean which determines whether the user is allowed to access the particular file or not.

Parameters:

  • boolean $can_access true if the user is already allowed to access the file, otherwise false
  • int $user_id the ID of the user to whom the file would be served
  • int $file_id the ID of the file to be served

Returns:

boolean true if the user should be allowed to access the file, otherwise false

Example:

function custom_groups_file_access_can_access(  $can_access, $user_id, $file_id ) {
	if ( $can_access ) {
		// additional verification ...
	}
	return $can_access;
}
add_filter( 'groups_file_access_can_access', 'custom_groups_file_access_can_access', 10, 3 );

We recommend to put this in a plugin of its own although a customized filter can also be added to your theme’s functions.php.
