WordPress特色图片的实际文件位置？

Question

I'm generating a query for certain posts in 'Trash'. I can retrieve the featured image URL, but I'm looking for a way to get the featured image file location on the server.

# generate the query
foreach ( $query as $post ) {
    $thumbID = get_post_thumbnail_id( $post->ID );
    $thumbObj = get_post( $thumbID );
    $source_url = $thumbObj->guid;
    # how do I get the string "/path/to/wordpress/media/library/thumbnail.jpg" ?
}

I can't find any WordPress function that returns the actual featured image file location.

There is no wp function but its easy enough to make your own, e.g.

function return_image_path($thumbID) {

    $image= wp_get_attachment_image_src($thumbID);
    $imagepath= str_replace(get_site_url(), $_SERVER['DOCUMENT_ROOT'], $image[0]);

    if($imagepath) return $imagepath;

    return false;

}
