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__
sMyAkismetKey = '__YOUR_AKISMET_KEY__';
$this->sWebsiteUrl = '__YOUR_WEBSITE_URL__';
$this->sAuthName = '__YOUR_NAME__';
$this->sAuthEml = '';
$this->sAuthUrl = '';
// 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 $this->oAkismet->isCommentSpam();
}
}
echo <<
form div {
margin:10px;
}
form label {
width:90px;
float:left;
display:block;
}
EOF;
if ($_POST) {
// draw debug information
echo '';
print_r($_POST);
echo '
';
// obtain sent info
$sPostAuthor = $_POST['author'];
$sCommentComment = $_POST['comment'];
// check for spam
$oMySpamProtection = new MySpamProtection();
$sAuthorCheck = ($oMySpamProtection->isSpam($sPostAuthor)) ? '"Author"marked as Spam' : '"Author"not marked as Spam';
$sCommentCheck = ($oMySpamProtection->isSpam($sCommentComment)) ? '"Comment"marked as Spam' : '"Comment"not marked as Spam';
echo $sAuthorCheck . '
' . $sCommentCheck;
}
?>
