联系表单/消息正文中的Php变量

我有一个联系人表单，只是传递了一些表单字段，我想知道是否有人可以帮助作为为什么?

html格式如下:

            <form enctype="multipart/form-data" method="post" action="referral.php" onsubmit="return submitForm()">
      <fieldset>
          <div class="field">
            <input name="name" id="name" type="text" class="validate" placeholder="Your Name" />
            <span class="form-msg" id="name-error">Please add your name</span>
          </div>
            <div class="field here-for-next-until">
              <input name="email" id="email" type="text" class="validate" placeholder="Your E-mail" class="text-input validate" />
              <span class="form-msg" id="email-error">Please add your e-mail address</span>
            </div>
            <div class="field">
              <input name="phone" id="phone" type="text" placeholder="Your Phone Number" class="text-input validate" />
              <span id="phone-error" class="form-msg" >Please add your phone number</span>
            </div>                        
            <div class="area here-for-next-until">
              <textarea name="message" id="message" class="text-input validate" placeholder="Introduce Yourself"></textarea><br/>
              <span class="form-msg" id="email-error">Please add an introduction to yourself</span>
              <input type="text" id="cap_val" name="cap_val" class="code validate" placeholder="Enter Code From Right"/>
              <img src="bin/captcha.php" id="cap"/><img src="images/refresh.jpg" id="cap-refresh" onclick="change_captcha()"/><br/>
            <span id="captcha-error" class="form-msg" >Please add the above code</span>
            <div class="clear here-for-next-until"></div>
          </div>
    </div>
   <div class="flt-lt w420">
    <h2 class="subheader">Client</h2>
          <div class="field">
            <input name="referralsname" id="name" type="text" class="validate" placeholder="Name" />
            <span class="form-msg" id="name-error">Please add your referrals name</span>
          </div>
            <div class="field here-for-next-until">
              <input name="referralsemail" id="email" type="text" class="validate" placeholder="E-mail address" class="text-input validate" />
              <span class="form-msg" id="email-error">Please add your referrals e-mail address</span>
            </div>
            <div class="field">
              <input name="referralsphone" id="phone" type="text" placeholder="Phone Number" class="text-input validate" />
              <span id="phone-error" class="form-msg" >Please add your referrals phone number</span>
            </div>                        
            <div class="area here-for-next-until">
              <textarea name="referralsmessage" id="message" class="text-input validate" placeholder="Introduce Yourself"></textarea><br/>
              <span class="form-msg" id="email-error">Please add an introduction to yourself</span>
            <div class="clear here-for-next-until"></div>
                        <div id="submit-holder">
              <input class="submit" type="submit" value="Submit"/>
              <input id="reset" class="submit" type="reset" value="Reset"/>
            </div>
          </div>
      </fieldset>
    </form>

基本上这是两个非常相似的联系表单并排共享一个提交按钮

发布后会变成这样:

$owner_email = 'myemail.co.uk';
  $subject = A message from your site visitor ' . $_POST["name"];
  $messageBody = "'nVisitor: " . $_POST["name"] . "'n";
  $messageBody .= "Email Address: " . $_POST['email'] . "'n";
  $messageBody .= "Phone Number: " . $_POST['phone'] . "'n";
  $messageBody .= "Message: " . $_POST['message'] . "'n";
  $messageBody = "'nVisitor: " . $_POST["referralsname"] . "'n";
  $messageBody .= "Email Address: " . $_POST['referralsemail'] . "'n";
  $messageBody .= "Phone Number: " . $_POST['referralsphone'] . "'n";
  $messageBody .= "Message: " . $_POST['referralsmessage'] . "'n";

然而，当我提交表单时，我只会得到一组详细信息(前4个$messageBody)

任何人能提供的帮助都将是非常感激的。
