function my_link($atts, $content = null) {
    extract(shortcode_atts(array(
        "href" => 'http://'
    ), $atts));

    return '<a href="'.$href.'">'.do_shortcode($content).'</a>';   // การคืนค่าให้ใส่ do_shortcode()
    
    // ถ้าเปลี่ยนเป็น
    // return '<a href="'.$href.'">'.$content.'</a>';   // link shortcode จะไม่รองรับ Nested
