代码移植Wp-Anti-spam

发表于 分类于

鉴于大师的小墙导致了所有评论被吞，如果不大刀阔斧改的话很麻烦，所以还是那套老思路，去从插件里面扒了算了，WP-Anti-Spam的代码也算简单，以前用过的话很明白的就知道功能了。

主要功能可以参考这张图。

WP-Anti-Spam由三个文件组成，说明文档可以忽略，后台功能咱么不要，所以……只剩下一个直接看代码。

function load\_wp\_anti\_spam\_lang(){ 
$currentLocale = get\_locale();
if(!empty($currentLocale)){
    $moFile = dirname(\_\_FILE\_\_) . "/lang/wp-anti-spam-" . $currentLocale . ".mo";
    if(@file\_exists($moFile) && is\_readable($moFile)) load\_textdomain('WP-Anti-Spam', $moFile);
}

}
add_filter(‘init’,’load_wp_anti_spam_lang’);

$wp_anti_spam_words = array();
if(!defined(‘WASINFO’)) define(‘WASINFO’,’(Protected by WP Anti Spam)’);

function wp_anti_spam($comment_data){

$wp\_anti\_spam\_words = explode("\\r\\n", get\_option("wp\_anti\_spam\_words"));
$comment\_fields = array('author','email','url','comment');

foreach($wp\_anti\_spam\_words as $wp\_anti\_spam\_word)
foreach($comment\_fields as $comment\_field)
if( $wp\_anti\_spam\_word != '' && isset($\_POST\[$comment\_field\]) ){
    if(eregi($wp\_anti\_spam\_word, $\_POST\[$comment\_field\]) !== false){
         wp\_die(\_\_('Error: The information you submit contains banned words.','WP-Anti-Spam').WASINFO);
    }
}

$visitor\_ip = (@getenv("REMOTE\_ADDR")) ? getenv("REMOTE\_ADDR") : $\_SERVER\['REMOTE\_ADDR'\];
if(in\_array($visitor\_ip,$wp\_anti\_spam\_words)){
    wp\_die(\_\_('Error: Your IP has been banned to leave comments.','WP-Anti-Spam').WASINFO);
}

if(get\_option("wp\_anti\_spam\_links")=='yes'){
    $links = '/http:\\/\\//u';
    if(preg\_match($links, $comment\_data\['comment\_content'\])){
        wp\_die(\_\_('Error: Links are not allowed in comments.','WP-Anti-Spam').WASINFO);
    }
}

if(get\_option("wp\_anti\_spam\_cn\_must")=='yes'){
    $cn\_char = '/\[一-龥\]/u';
    if(!preg\_match($cn\_char, $comment\_data\['comment\_content'\])){
        wp\_die(\_\_('Error: Comments must contain Chinese.','WP-Anti-Spam').WASINFO);
    }
}

return($comment\_data);

}

add_filter(‘preprocess_comment’,’wp_anti_spam’);
?>

}

?>

很明显。后台处理的一些功能需要删除，否则会出错，像什么

Protected by WP Anti Spam

更加是有碍市容了= =直接删掉。引用的代码放在里

wp_die(__(‘Error: Links are not allowed in comments.’,’WP-Anti-Spam’).WASINFO);

这里的Error：……可以修改成你要的文字提醒读者，比如我：请把http://去掉发布~

一些功能可以通过英文看出来，不需要的话把与之关联的几行代码删除就可以了。

当然，这样子比如我去掉了中文限定之后评论自由度是高了，但总会有漏网之鱼，在设置的评论黑名单里我加了

tumblr.com
facebook.com

然后基本上就可以了。

好吧我修改之后是酱紫的：

'; } add\_action('comment\_form','wp\_anti\_spam\_hidden'); function wp\_anti\_spam\_spambots($spambots\_check){ if(!isset($\_POST\['human\_form'\]) || $\_SESSION\['unique\_session'\] != $\_POST\['human\_form'\]){ wp\_die(\_\_('Error: You are a automated spambot or your browser does not enable Cookie.','WP-Anti-Spam').WASINFO); } return $spambots\_check; } add\_filter('preprocess\_comment','wp\_anti\_spam\_spambots'); } function was\_app\_get\_html($url,$cookie=''){ $curl = curl\_init($url); $useragent="Mozilla/5.0 (Windows NT 5.1; rv:6.0.1) Gecko/20100101 Firefox/6.0.1"; curl\_setopt($curl, CURLOPT\_RETURNTRANSFER, true); curl\_setopt ($curl, CURLOPT\_USERAGENT, $useragent); if ($cookie<>'') { curl\_setopt ($curl, CURLOPT\_COOKIE, $cookie); } $data = curl\_exec($curl); curl\_close($curl); return $data; } function was\_no\_avatar\_to\_spam($comment){ $emaildata = md5( strtolower($comment\['comment\_author\_email'\]) ); $urldata = 'http://www.gravatar.com/avatar/'. $emaildata .'?d=404'; $avatarinfo = was\_app\_get\_html( $urldata ); if(substr($avatarinfo,0,3)=='404'){ if(get\_option("wp\_anti\_spam\_gravatar")=='mark-it-as-spam' && !is\_user\_logged\_in()){ add\_filter('pre\_comment\_approved', create\_function('', 'return "spam";')); } if(get\_option("wp\_anti\_spam\_gravatar")=='block-it' && !is\_user\_logged\_in()){ wp\_die(\_\_('Error: You have to apply for an avatar at Gravatar.com.','WP-Anti-Spam').WASINFO); } } return $comment; } add\_action('preprocess\_comment', 'was\_no\_avatar\_to\_spam', 1); if(get\_option("wp\_anti\_spam\_min")!='' && get\_option("wp\_anti\_spam\_max")!=''){ function was\_comment\_length($incoming\_comment){ if(mb\_strlen($incoming\_comment\['comment\_content'\],'utf-8')get\_option("wp\_anti\_spam\_max")) wp\_die(\_\_('Error: The words you input does not meet the Word Limit.','WP-Anti-Spam').WASINFO); return($incoming\_comment); } add\_filter('preprocess\_comment','was\_comment\_length'); } if(get\_option("wp\_anti\_spam\_deactivate")=='yes'){ function wp\_anti\_spam\_deactivate(){ global $wpdb; $remove\_options\_sql = "DELETE FROM $wpdb->options WHERE $wpdb->options.option\_name like 'wp\_anti\_spam\_%'"; $wpdb->query($remove\_options\_sql); } register\_deactivation\_hook(\_\_FILE\_\_,'wp\_anti\_spam\_deactivate'); } if(get\_option("wp\_anti\_spam\_support")!='no'){ function support\_author(){ echo ''; } add\_action('comment\_form','support\_author'); } ?>
