get_attached_file( int $attachment_id, bool $unfiltered = false )
Retrieve attached file path based on attachment ID.
Description Description
By default the path will go through the ‘get_attached_file’ filter, but passing a true to the $unfiltered argument of get_attached_file() will return the file path unfiltered.
The function works by getting the single post meta name, named ‘_wp_attached_file’ and returning it. 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 Parameters
- $attachment_id
-
(int) (Required) Attachment ID.
- $unfiltered
-
(bool) (Optional) Whether to apply filters.
Default value: false
Return Return
(string|false) The file path to where the attached file should be, false otherwise.
