WordPress 如何实现删除文章并通知投稿作者不通过理由

我们的modown主题里有通知功能，那么如何实现删除待审文章时附上不通过的理由并通知投稿作者呢？

下面模板兔附上一个简单的代码供参考：

add_action( 'post_submitbox_misc_actions', 'modown_delete_notice_metabox' );  function modown_delete_notice_metabox(){  global $post;  echo '<div class="misc-pub-section"><a href="javascript:;" class="submitdelete modown-delete-notice" data-id="'.$post->ID.'">移动至回收站并通知作者</a></div>    <script>  jQuery(".modown-delete-notice").click(function(){  var ret = prompt("删除理由", "");  if(ret !== null && ret != "") {  //console.log(ret);  jQuery.ajax({  url: ajaxurl,  data: {  pid: jQuery(this).data("id"),  why: ret,  action: "modown_delete_notice"  },  dataType: "json",  type: "POST",  success: function(t) {  if(t.status == 1){  location.href="/wp-admin/edit.php";  }else{  alert(t.msg);  }  },  error: function(XMLHttpRequest, textStatus, errorThrown) {    }  })  }  });  </script>  ';  }      function modown_delete_notice_callback(){  global $wpdb,$current_user;  date_default_timezone_set('Asia/Shanghai');   $status = 0;$msg = '处理失败';  if(current_user_can('administrator')){  $post_id = $_POST['pid'];  $cpost = get_post($post_id);  _mbt_add_notice($cpost->post_author, sprintf(__('您好，您发表的文章《%s》审核不通过，原因：'.$_POST['why'].'。','mobantu'), $cpost->post_title), 'post_trash', $post_id);  wp_trash_post($post_id);  $status = 1;  }    $result = array(  'status' => $status,  'msg' => $msg  );    header('Content-type: application/json');  echo json_encode($result);  exit;  }  add_action( 'wp_ajax_modown_delete_notice', 'modown_delete_notice_callback');
