get_attached_file( int $attachment_id, bool $unfiltered = false ): string|false
Retrieves attached file path based on attachment ID.
Contents
Description
By default the path will go through the ‘get_attached_file’ filter, but passing true to the $unfiltered argument will return the file path unfiltered.
The function works by retrieving the _wp_attached_file post meta value.
This is a convenience function to prevent looking up the meta name and provide a mechanism for sending the attached filename through a filter.
Parameters
-
$attachment_idint Required -
Attachment ID.
-
$unfilteredbool Optional -
Whether to skip the 'get_attached_file' filter.
Default:
false
Return
string|false The file path to where the attached file should be, false otherwise.
