wordpress自定义文章类型save_post的hook钩子

        有时候，我们要在发布、编辑自定义文章类型时，做一些动作，比如发送邮件通知，发送短信通知，给这个用户添加一些标记，比如给他加钱、加积分等等。那么可以用以下几种方法实现：

1、借用save_post

add_action('save_post','save_post_callback');
function save_post_callback($post_id){
    global $post; 
    if ($post->post_type != 'MY_CUSTOM_POST_TYPE_NAME'){
            return;
    }
    //if you get here then it's your post type so do your thing....
}
add_action('save_post','save_post_callback');
function save_post_callback($post_id){
    global $post; 
    if ($post->post_type != 'MY_CUSTOM_POST_TYPE_NAME'){
            return;
    }
    //if you get here then it's your post type so do your thing....
}
add_action('save_post','save_post_callback');
function save_post_callback($post_id){
    global $post; 
    if ($post->post_type != 'MY_CUSTOM_POST_TYPE_NAME'){
            return;
    }
    //if you get here then it's your post type so do your thing....
}

2、其实也时save_post的一种变形save_post_{$post_type}

add_action( 'save_post_my_post_type', 'wpse63478_save' );
function wpse63478_save(){
    //save stuff
}
add_action( 'save_post_my_post_type', 'wpse63478_save' );
function wpse63478_save(){
    //save stuff
}
add_action( 'save_post_my_post_type', 'wpse63478_save' );
function wpse63478_save(){
    //save stuff
}
