前阵子看到blinux的blog里，把已评论过的用户隐藏起用户名和电子邮件等框。虽然是细节，但看起来感觉就是不一样。谁会喜欢看到满眼的输入框呢！！
逞着今天有空，决定我也弄一下。 但是只是评论后隐藏好你没多大效果，对第一次评论的人还是很不友好的，所以决定打开Wordpress的匿名评论，只要在后台评论里去掉那个"评论时一定要邮箱和名字“的选项去掉就行了！
匿名是匿名了，但输入框还在，利用原来MG12的改善WordPress 访客评论时的用户体验一文的代码进行改进一下。
具体实现所的效果就如我blog的评论框一样!
先找到原来模板里的输入框代码！
<p><input type="text" name="author" id="author" value="<?php echo $comment_author; ?/>" size="22" tabindex="1" < ?php if ($req) echo "aria-required='true'"; ?> />
<label for="author"><small>Name < ?php if ($req) echo "(required)"; ?></small></label></p>
<p><input type="text" name="email" id="email" value="<?php echo $comment_author_email; ?/>" size="22" tabindex="2" < ?php if ($req) echo "aria-required='true'"; ?> />
<label for="email"><small>Mail (will not be published) < ?php if ($req) echo "(required)"; ?></small></label></p>
<p><input type="text" name="url" id="url" value="<?php echo $comment_author_url; ?/>" size="22" tabindex="3" />
<label for="url"><small>Website</small></label></p>
进行替换
