wp_upload_dir

Definition:
function wp_upload_dir( $time = null ) {}

Get an array containing the current upload directory’s path and url.
Checks the ‘upload_path’ option, which should be from the web root folder, and if it isn’t empty it will be used. If it is empty, then the path will be ‘WP_CONTENT_DIR/uploads’. If the ‘UPLOADS’ constant is defined, then it will override the ‘upload_path’ option and ‘WP_CONTENT_DIR/uploads’ path.

Parameters

  • string $time: Optional. Time formatted in ‘yyyy/mm’.

Return values

returns:See above for description.

Defined filters

  • upload_dir
    apply_filters( 'upload_dir', array( 'path' => $dir, 'url' => $url, 'subdir' => $subdir, 'basedir' => $bdir, 'baseurl' => $burl, 'error' => false )
