有可能stop author to publish post, 强迫他Submit For Preview. 只需将此代码添加到functions.php 你们都完了。

<?php
   function take_away_publish_permissions() {
        $user = get_role(\'author\');
        $user->add_cap(\'publish_posts\',false);
   }
   add_action(\'init\', \'take_away_publish_permissions\' );
?>

**更新代码**此共享代码用于在作者更新帖子时将帖子状态设置为预览或挂起

function postPending($post_ID)
 { 
     if(get_role(\'author\'))
     {
        //Unhook this function
        remove_action(\'post_updated\', \'postPending\', 10, 3);

        return wp_update_post(array(\'ID\' => $post_ID, \'post_status\' => \'pending\'));

        // re-hook this function
        add_action( \'post_updated\', \'postPending\', 10, 3 );
     }
 }
add_action(\'post_updated\', \'postPending\', 10, 3);

NOTE: 如果调用包含save\\u post挂钩的wp\\u update\\u post等函数，那么挂钩函数将创建一个无限循环。为了避免这种情况，请在调用所需函数之前先取消钩住函数，然后再重新钩住它。有关详细信息，请查看此link
