get_attached_file( int $attachment_id, bool $unfiltered = false )

Retrieve attached file path based on attachment ID.


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.



(int) (Required) Attachment ID.


(bool) (Optional) Whether to apply filters.

Default value: false


(string|false) The file path to where the attached file should be, false otherwise.

	// If the file is relative, prepend upload dir.
	if ( $file && 0 !== strpos( $file, '/' ) && ! preg_match( '|^.:\\\|', $file ) && ( ( $uploads = wp_get_upload_dir() ) && false === $uploads['error'] ) ) {
		$file = $uploads['basedir'] . "/$file";

	if ( $unfiltered ) {
		return $file;
