今天看了下博客~~恩，很正常，呵呵，也没什么人看没什么人留言~~然后进后台看看~~我 日~~500多条评论~~马上悟了，遭垃圾评论了~~
原来刚开始用WordPress的时候就有想过装个反垃圾评论的插件~~自带的那个Akismet要申请key，懒得申请~~其他的又不知道好坏，好不好用，简单不简单，耗不耗资源。而且又一直没发现有垃圾评论，就这么一直留着了~~谁知道，前段时间net . ru被封，无奈之下把备份博客放到了国内地平线空间，继续用net . ru域名~~结果今天居然收到垃圾评论了~~呵呵~~
是时候弄个反垃圾的了~~不想太复杂的，也不太喜欢安装插件，插件这东西，太多了不好~~于是就找那个印象中算术题的~~找到了一个用添加代码的办法来实现的~~这个好~~呵呵~~~
下面一段是转自：Adwi Blog 的
方法：
1.修改 wp-comments-post.php ：
查找：
if ( '' == $comment_content )
在其上面添加代码：
//Fufu_checkcode
if ( !$user->ID ) {
$aaa = trim($_POST[aaa]);
$bbb = trim($_POST[bbb]);
$subab = trim($_POST[subab]);
if((($aaa+$bbb)!=$subab)|| empty($subab)){
wp_die( __('Error: Please enter the correct results of the math problems.') );
}
}
//Fufu_end
然后修改当前主题目录下的 comments.php (我用的elegantbox) ，在适当的位置添加代码，我是在提交按钮之前添加的，即查找：
<input name="submit" type="submit" id="submit"
在其前面添加代码：
<?php if (!$user_ID) : ?>
<?php $aaa=rand(0,5); $bbb=rand(3,9); ?>
<input type="text" name="subab" id="subab" size="2" tabindex="5" /><?php echo $aaa; ?>+<?php echo $bbb; ?>?
<?php if ($req) _e('(required)','elegantbox'); ?>
<input name="aaa" value="<?php echo $aaa; ?>" type="hidden" />
<input name="bbb" value="<?php echo $bbb; ?>" type="hidden" />
<?php endif; ?>如果你的主题不是 elegantbox的话下面这段代码要做相应的修改，这段代码的意思是“(必填)”需要对应模板的语言。
<?php if ($req) _e('(required)', 'elegantbox'); ?>
修改好后，用用看实际的效果如何吧。
------------------------------------------------我是华丽的分割线--------------------------------------------
上面是别人的文章~~呵呵，虽然功能很简单，可以自己添加，但是懒得去找到底在哪添加，于是找到了他的文章~~就直接用了~~算数结果的输入框可以自己改，想要什么效果应该都很容易改吧~~代码实在不复杂，不过我觉得还是放那个位置的确不错~~因为在登录，或者曾经输入过信息的时候，再次评论会根据cookie，不用再输入信息，而且也不显示。所以如果放在姓名邮件网址的下面会很孤零零的。
他的代码，我就加了一小句，呵呵~~因为他已经设置了如果是注册用户，就不用输入答案也能评论，不过在评论页面这个算术题还是会显示出来，
我就在第二段代码小加了个<?php if (!$user_ID) : ?> 和代码之后加<?php endif; ?>
这样一来，已登录的注册用户看的时候就不会显示算术题了，呵呵~~
这方法好,学习
哈哈~进来学习一下哇
