将工作复选框添加到联系人表单

Question

我试图将复选框添加到我的联系表单中。我有一个有3个复选框的工作联系表单。当我在本页找到的php代码（​​）时，我的复选框不再是可点击的，但是当电子邮件发送电子邮件中出现所有三个复选框时。我认为在某个地方必须有一个简单的解决方案，但是我已经花了整整一天的时间来研究这个问题，而且这一切都是我所能得到的。

如何获取可点击的复选框，并将所选框包含在电子邮件中？

这里是我的html

<section class="contact"> 
    <form id="contact" action="html_form_send.php" method="post"> 
    <fieldset title="About you"> 
    <legend><span>About you</span></legend> 
    <label for="name">Name</label> 
    <input type="text" name="name" id="name" tabindex="10" class="txtinput" placeholder="Your name" required> 
    <label for="email">Email</label> 
    <input type="email" name="email" id="email" tabindex="20" class="txtinput" placeholder="valid email" required> 
    </fieldset> 
    <fieldset title="Your turn"> 
    <legend><span>Your turn</span></legend> 
    <p>What, exactly then, are you after?</p> 
    <div> 
    <div class="tag">checkbox1</div> 
    <input type="checkbox" id="checkbox-1" class="regular-checkbox big-checkbox" value="Yes" /> 
    <label for="salvation"></label> 
    </div>  
    <div> 
    <div class="tag">checkbox2</div> 
    <input type="checkbox" id="checkbox-2" class="regular-checkbox big-checkbox" value="Yes" /> 
    <label for="question"></label> 
    </div>  
    <div> 
    <div class="tag">checkbox3</div> 
    <input type="checkbox" id="checkbox-3" class="regular-checkbox big-checkbox" value="Yes" /> 
    <label for="other"></label> 
    </div> 
    <label for="comment" class="inline"></label> 
     <label for="discourse">Write your comments here</label> 
    <textarea id="discourse" name="discourse" tabindex="30" class="txtinput" rows="7" placeholder="This is where your thoughts go"> 
    </textarea> 

    <section id="buttons"> 
    <input type="reset" name="reset" id="resetbtn" class="resetbtn" value="Reset"> 
    <input type="submit" name="submit" id="submitbtn" class="submitbtn" tabindex="40" value="Send away!"> 
    <br style="clear:both;"> 
    </section>

如果复选框不能点击则是最有可能是一些其他的元素（一个或多个）坐在上面摆着。使用浏览器的开发人员工具是发现此问题的最快捷方式。 PHP不会影响它们是否可点击。

如果我猜测这将是他们的标签坐在他们上面。 （请注意，应避免使用像这样的空元素。）

复选框（和其他表单元素）必须具有name属性才能与表单一起提交。
