是的，是的。就在昨天，我不得不做一些类似的事情，并找到了这个解决方案。与链接解决方案大致相同，但有更多的错误检查。

<?php
add_filter(\'upload_dir\', \'cgg_upload_dir\');
function cgg_upload_dir($dir)
{
    // xxx Lots of $_REQUEST usage in here, not a great idea.

    // Are we where we want to be?
    if (!isset($_REQUEST[\'action\']) || \'upload-attachment\' !== $_REQUEST[\'action\']) {
        return $dir;
    }

    // make sure we have a post ID
    if (!isset($_REQUEST[\'post_id\'])) {
        return $dir;
    }

    // modify the path and url.
    $type = get_post_type($_REQUEST[\'post_id\']);
    $uploads = apply_filters("{$type}_upload_directory", $type);
    $dir[\'path\'] = path_join($dir[\'basedir\'], $uploads);
    $dir[\'url\'] = path_join($dir[\'baseurl\'], $uploads);

    return $dir;
}
