如何对动态短代码使用过滤器？

Question

我只是创建这样的短代码：

add_shortcode( 'demo1', 'demo1_init' ) );
add_shortcode( 'demo2', 'demo2_init' ) );

function demo1_init() {
   // Shortcode Def. here...
}

function demo2_init() {
   // Shortcode Def. here...
}

如何使用过滤器动态创建这些短代码？像这样的东西。例如

 $a = array(
        "demo1"       =>  "demo1_init",
        "demo2"       =>  "demo2_init",
);

以下应该可以完成工作

function demo1_init() {
    // Shortcode Def. here...
    return "demo1";
}

function demo2_init() {
    // Shortcode Def. here...
    return "demo2";
}

function register_shortcodes() {

    $shortcodes = array(
        "demo1"   =>  "demo1_init",
        "demo2"   =>  "demo2_init",
    );

    foreach($shortcodes as $shortcode => $func) {       
        add_shortcode($shortcode, $func);
    }

}
add_action( "init", "register_shortcodes" );
