我使用WordPress的oEmbedd功能。一切正常，但我需要在iframe中设置自定义参数

所以我尝试了一下，但没有成功：

function my_oembed_fetch_url( $provider, $url, $args ) {
    // You can find the list of defaults providers in WP_oEmbed::__construct()
    if ( strpos( $provider, \'soundcloud.com\' ) !== false) {

        if ( isset( $args[\'show_artwork\'] ) ) {
            $provider = add_query_arg( \'show_artwork\', absint( $args[\'show_artwork\'] ), $provider );
        }
    }

    return $provider;
}

wp_oembed_get(\'https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/number-exampleXXXXXXX\', array(\'show_artwork\' => \'false\'));
