php – 保存所有帖子数据和发布元后,哪个WordPress钩子会触发？

我有一个自定义的帖子类型crm,我需要在每个crm保存或更新后发送邮件.我用户cmb2用于某些自定义元类主题,用户等.我知道save_post挂钩在发布后保存(根据wordpress codex)在我的情况下我用两个参数调用save_post(id和post)帖子不包含更新值.这是我的代码：

function send_mail_to_user($id, $post){
    $crm = $post;
    $user_email = array();
    if($crm->vc_all_vc == 'on'){
        $args = array('orderby' => 'display_name');
        $wp_user_query = new WP_User_Query($args);
        $authors = $wp_user_query->get_results();
        if (!empty($authors)) {
            foreach ($authors as $author) {
                array_push($user_email , $author->user_email );
            }
        } 
    }
    else{
        $to_users = $crm->vc_users;
        $to_program = $crm->vc_program;
        $to_group = $crm->vc_group;
        $to_excode = $crm->vc_ex_code;
        foreach ($to_users as $key => $value) {
            $user_data = get_userdata($value);
            array_push($user_email, $user_data->user_email);
        }
        foreach ($to_program as $key => $value) {
            $users = get_users( array('Meta_key'     => 'programs'  ) );
            if($users){ 
                foreach ($users as $index => $data) {
                    if(in_array($value , explode('#', $data->programs))){
                        if(! in_array($data->user_email, $user_email)  )
                        {
                            array_push($user_email, $data->user_email);
                        }
                    }
                }
            }
        }
        foreach($to_group as $group) {
            $term = get_term_by('slug', esc_attr($group), 'user-group');
            $user_ids = get_objects_in_term($term->term_id, 'user-group');
            foreach($user_ids as $user_id){
                $fc_user = get_userdata($user_id);
                if(! in_array($fc_user->user_email, $user_email)  )
                {
                    array_push($user_email, $fc_user->user_email);
                }
            }   
        }
        foreach($to_excode as $codes) {
            $value = explode('*',$codes)[1];
            $users = get_users( array('Meta_key'     => 'programs'  ) );
            if($users){ 
                foreach ($users as $index => $data) {
                    if(in_array($value , explode('#', $data->programs))){
                        if(! in_array($data->user_email, $user_email)  )
                        {
                            array_push($user_email, $data->user_email);
                        }
                    }
                }
            }   
        }
    }
    foreach($user_email as $index => $email){
        $to      = $email;
        $subject = $crm->vc_subject;
        $body    = $crm->post_content;
        $headers = array(
        'Content-Type: text/html; charset=UTF-8'
        );
        wp_mail($to, $subject, $body, $headers);
    }
}

add_action( 'save_post', 'send_mail_to_user', 10, 2 ); 

我也尝试使用publish_post钩子,在创建新帖子时工作正常,但更新时它的工作原理相同.我也尝试过edit_post和post_updated钩子,但我永远无法检索我的更新数据.

那我怎么解决呢？哪个动作挂钩会给我所有的新数据？
提前致谢.

解决方法:

尝试使用post_updated并使用$post_after对象.
