是的，这可能和以前一样。我不知道你为什么认为过滤器不再传递参数了。

add_filter(\'attachment_fields_to_edit\', \'user16975_edit_fields\', 10, 2);
function user16975_edit_fields($form_fields, $attachment){

    // check for an audio attachment
    if ( substr($attachment->post_mime_type, 0, 5) == \'audio\' ) {
        $playertag =  $playertag = "[audio ".wp_get_attachment_url($attachment->ID)."]";
        $form_fields["audioplayer"] = array(
            "label" => "Audio player",
            "input" => "html",
            "html" => "<button type=\'button\' class=\'button\' data-link-url=\'$playertag\' audioplayer=\'audio-player-{$attachment->ID}\'>Audio Player</button>",
        );
    }

    return $form_fields;
}
