wordpress拉黑恶意评论并且不写入数据库

效果

教程

将以下代码加入到functions.php中

/*评论*/
function mac_fuckspam($comment) {  
    if(  is_user_logged_in()){ return $comment;} //登录用户无压力...  
     
    if( wp_blacklist_check($comment['comment_author'],$comment['comment_author_email'],$comment['comment_author_url'], $comment['comment_content'], $comment['comment_author_IP'], $comment['comment_agent'] )){  
        header("Content-type: text/html; charset=utf-8");  
        exit('<ol class="jiubpinlun">你填写的某项信息或IP地址已被列入黑名单，无法进行评论，请文明评论!</ol>');  
    }  else  {  
        return $comment;   
    }  
}   
add_filter('preprocess_comment', 'mac_fuckspam');

将下面样式插入到你主题样式文件去

.jiubpinlun {
	display: block;
	font-size: 14px;
	text-align: center;
	background-color: red;
	color: #ffffff;
	border: 1px solid #ccc;
	margin-bottom:10px;
}
