使用 Akismet 防止垃圾评论

Akismet是一个优秀的防Spam垃圾留言的优秀插件，绝大多数wordpress blogger都在使用，有了akismet之后，基本上不用担心垃圾留言的烦恼了。然而，人无完人，插（件）无完插！Akismet也并非完美，最近， 我常在被Akismet评判为垃圾的留言中找到“好人”的留言，然而，有时时间长了就自动删除了，损失珍贵的友情和留言。

别忘了修改代码中的 __YOUR_AKISMET_KEY__, __YOUR_WEBSITE_URL__ and __YOUR_NAME__

<?

require_once (&#39;classes/Akismet.class.php&#39;);

class MySpamProtection {

 // variables
 var $sMyAkismetKey;
 var $sWebsiteUrl;
 var $sAuthName;
 var $sAuthEml;
 var $sAuthUrl;
 var $oAkismet;

 // constructor
 public function MySpamProtection() {
 // set necessary values for variables
 $this->sMyAkismetKey = &#39;__YOUR_AKISMET_KEY__&#39;;
 $this->sWebsiteUrl = &#39;__YOUR_WEBSITE_URL__&#39;;
 $this->sAuthName = &#39;__YOUR_NAME__&#39;;
 $this->sAuthEml = &#39;&#39;;
 $this->sAuthUrl = &#39;&#39;;

 // Akismet initialization
 $this->oAkismet = new Akismet($this->sWebsiteUrl ,$this->sMyAkismetKey);
$this->oAkismet->setCommentAuthor($this->sAuthName);
$this->oAkismet->setCommentAuthorEmail($this->sAuthEml);
$this->oAkismet->setCommentAuthorURL($this->sAuthUrl);
}

 public function isSpam($s) {
 if (! $this->oAkismet) return false;

$this->oAkismet->setCommentContent($s);
 return $this->oAkismet->isCommentSpam();
}
}
