当然您需要两件事—设置页面和自定义短代码处理程序。第一个有点过于宽泛，无法在这里详细讨论，但是this tutorial 应该有助于你开始。您还可以check out the codex, 如果你真的被卡住了，也可以在这里发回一个新问题。

现在来看短代码：

function wpse_203387_param_shortcode( $atts ) {
    // [PARAM name="data"], $atts will be an array of name => data pairs
    // [PARAM data], $atts will be a numeric array with one element, "data"

    // In this case, we just always grab the first value/data
    $name = array_shift( $atts );

    switch ( strtolower( $name ) ) {
        case \'youtubehome\' : // [PARAM youtubehome]
            $data = get_option( \'theme_options\' ); // This is purely for example, use the data structure/names that match your settings API config

            return $data[\'youtube_setting\'];

        case \'anotherparam\' : // [PARAM anotherparam]
            return \'something_else\';
    }
}

add_shortcode( \'PARAM\', \'wpse_203387_param_shortcode\' );

function wpse_203387_options_page_capability( $capability ) {
    return \'edit_theme_options\';
}

add_filter( \'option_page_capability_my-theme-settings-name\', \'wpse_203387_options_page_capability\' );
