php中使用Akismet防止垃圾評論的代碼

更新時(shí)間：2011年06月10日 00:49:43 作者：

Akismet是一個(gè)優(yōu)秀的防Spam垃圾留言的優(yōu)秀插件，絕大多數(shù)wordpress blogger都在使用，有了akismet之后，基本上不用擔(dān)心垃圾留言的煩惱了。

然而，人無完人，插（件）無完插！Akismet也并非完美，最近，我常在被Akismet評判為垃圾的留言中找到“好人”的留言，然而，有時(shí)時(shí)間長了就自動(dòng)刪除了，損失珍貴的友情和留言。
別忘了修改代碼中的 __YOUR_AKISMET_KEY__, __YOUR_WEBSITE_URL__ and __YOUR_NAME__

復(fù)制代碼代碼如下:

 
<? 
require_once ('classes/Akismet.class.php'); 
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 = '__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 <<<EOF

if ($_POST) {

print_r($_POST); 
echo '</pre>'; 
// 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';
