wordpress使用代码来过滤和阻止垃圾评论

来源:向日葵气味的武士  时间:2019-07-29 09:49:34

​​将下面代码写入主题文件夹下的functions.php文件即可

方法一:过滤内容为全英文和含有日文的垃圾评论

/* 阻止垃圾评论 */function refused_spam_comments( $comment_data ) {$pattern = '/[一-龥]/u';if(!preg_match($pattern,$comment_data['comment_content'])) {wp_die('评编辑论必须含中文!');}return( $comment_data );}add_filter('preprocess_comment','refused_spam_comments');

方法二:反垃圾评论代码

/* 垃圾评论拦截 */class anti_spam {function anti_spam() {if ( !current_user_can('level_0') ) {add_action('template_redirect', array($this, 'w_tb'), 1);add_action('init', array($this, 'gate'), 1);add_action('preprocess_comment', array($this, 'sink'), 1);}}function w_tb() {if ( is_singular() ) {ob_start(create_function('$input','return preg_replace("#textarea(.*?)name=(["'])comment(["'])(.+)/textarea>#","textarea$1name=$2w$3$4/textarea>",$input);') );}}function gate() {if ( !emptyempty($_POST['w']) && emptyempty($_POST['comment']) ) {$_POST['comment'] = $_POST['w'];} else {$request = $_SERVER['REQUEST_URI'];$referer = isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : '隐瞒';$IP = isset($_SERVER["HTTP_X_FORWARDED_FOR"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] . ' (透过代理)' : $_SERVER["REMOTE_ADDR"];$way = isset($_POST['w']) ? '手动操作' : '未经评论表格';$spamcom = isset($_POST['comment']) ? $_POST['comment'] : null;$_POST['spam_confirmed'] = "请求: ". $request. "n来路: ". $referer. "nIP: ". $IP. "n方式: ". $way. "n內容: ". $spamcom. "n -- 记录成功 --";}}function sink( $comment ) {if ( !emptyempty($_POST['spam_confirmed']) ) {if ( in_array( $comment['comment_type'], array('pingback', 'trackback') ) ) return$comment;//方法一: 直接挡掉, 將 die(); 前面两斜线刪除即可.die();//方法二: 标记为 spam, 留在资料库检查是否误判.//add_filter('pre_comment_approved', create_function('', 'return "spam";'));//$comment['comment_content'] = "[ 判断这是 Spam! ]n". $_POST['spam_confirmed'];}return$comment;}}$anti_spam = new anti_spam();代码后面提供了两种对付垃圾评论的办法,一种是直接阻止评论,另一种是将垃圾评论放在Wordpress评论的待审核队列中,默认的是第一种,如果你想使用第二种,请给die();加上//,然后去掉“方法二”下面代码的//符号。

方法三:过滤内容包含任意日文字符的垃圾评论

/* 阻止日文垃圾评论 */function BYMT_comment_jp_post( $incoming_comment ) {$jpattern ='/[ぁ-ん]+|[ァ-ヴ]+/u';if(preg_match($jpattern, $incoming_comment['comment_content'])){wp_die( "禁止有日文字符的评论 You should type some Chinese word" );}return( $incoming_comment );}add_filter('preprocess_comment', 'BYMT_comment_jp_post');
