Hidden Form Fields To Prevent Bot Spam 隐藏表单栏位，以防止垃圾邮件的僵尸

Augie (from intellectualcapitalreport.com ) presented a spam prevention method idea which we’ve been talking about under a previous post this past week: HowTo Eliminate Wordpress Trackback Comment And Pingback Spam . Augie （从intellectualcapitalreport.com ）提出了防止垃圾邮件的方法想法，我们已经谈论根据以前的职位过去的这个星期： 如何消除WordPress的评论和引用Pingback垃圾邮件。 The basic idea is to provide an extra input field which is hidden to a user when viewed normally from the browser.基本的思路是提供一个额外的输入栏位这是隐藏到用户观看时，通常从浏览器。 This means if you check your form data when a submission is being processed, you can determine if the field is still empty.这就意味着，如果您检查表单数据时，提交正在处理中，您可以决定是否领域仍是空白。 If it is filled out, then a bot must have auto filled the field.如果是填写，然后机器人必须具备自动填补了外地。

Spam Field Details垃圾场的细节

The naming convention used on a hidden field should be named “email” or “url” to trick the bot.在命名惯例上使用隐藏字段应该命名为“电子邮件”或“网址”欺骗僵尸。 Your real email field will then of course need to be named something else.您的真实的电子邮件外地然后将当然需要命名为别的东西。 A small price to pay for less house cleaning.一个很小的代价不到房子的清洁。

Another key to all of this is to wrap your trap (haha) in a DIV so that the a bot cant tell that the field is hidden.另一个关键，所有这一切都结束的陷阱（哈哈）在一个除法，使以BOT不能告诉外地是隐藏的。 Marking it with type=”hidden” on the input tag itself is a bit of a giveaway.可塑与类型= “隐藏”的投入标记本身就是一个有点赠品。 Assigning an id or class to the div and specifying display:none; would cause the bot a lot of extra work which most probably aren’t programmed for.分配一个ID或类别的专区，并指明显示：无;将导致僵尸了许多额外的工作，最有可能不是编程。 You could also use a built in id or class directly on the div to specify it as a hidden field.您也可以使用内置的ID或类别直接在专区指定它作为一个隐藏的领域。

Hidden Input Field Code隐藏输入栏位代码

Here is an example of what your code would look like:下面是一个例子，您的代码将如下所示：

1. CSS code would look like this:
2. #email {
3. display: none
4. }
6. OR if you're doing it by the div:
8. .specialfield {
9. display: none
10. }
12. Your form would look something like this:
13. <form method="post" action="yourformprocessor.php">
14. <div class="specialfield"><input id="email" type="text"></div>
15. <input id="realemail" type="text">
16. </form>

Using Hidden Fields使用隐藏字段

It isn’t too much of a stretch to add this to a custom solution or implement it into a Wordpress comments or form plugins because id’s and classes are assigned to input fields by default.这不是扯得太远了以新增此项目自订的解决办法或实施到WordPress的意见或形式的插件，因为识别码和班级被分配到输入栏位的预设值。 If you’re not already using a form plugin check out:如果您尚未使用的一种形式插件检查：

cforms II or Contact Form 7 (my preference). cforms II或 联系表7 （我偏好） 。

If I get enough requests I’ll write a post which explains how to implement this into Wordpress comments in a similar manner in which I setup the Enhanced Numbered Equation CAPTCHA .如果我得到足够的要求我会撰写文章解释如何执行这一到WordPress的评论也以相同方式在我安装增强编号方程CAPTCHA 。

The More Spam Defense The Better在更多的垃圾邮件防御更好

I don’t have a lot of experience in using spam bots, but this is a promising way to enhance our line of defense against spam.我不拥有丰富的经验在使用防垃圾邮件程序，但是这是一种很有前途的方式加强我们的防线垃圾邮件。 More importantly, its not intrusive on a users browsing experience.更重要的是，它没有侵入了用户的浏览体验。 Unlike a CPATCHA, it requires a valid visitor to do nothing!不同CPATCHA ，它需要一个有效的访客做什么！
