Php variable in contact form / message body - php

Question

I have a contact form that is only passing over some of the form fields and i wondered if anyone can help as to why?
The html form is as follows:
<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>
Basically this is two very similar contact forms side by side that share a submit button
When posted it goes to this:
$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";
However when I submit the form I onyl get one set of details (the first 4 $messageBody)
Any help anyone could offer would be greatly appreciated.
Thanks again
David

Answer 1

Change:
$messageBody = "\nVisitor: " . $_POST["referralsname"] . "\n";
To:
$messageBody .= "\nVisitor: " . $_POST["referralsname"] . "\n";
(.= instead of =, you are re-assigning value to $messageBody instead of chaining it to $messageBody)

Answer 2

if i had to guess, i would say it is because you are repeating the IDs. In HTML element IDs have to be unique. make all IDs match your "name" values. im referring to
<input name="phone" id="phone"....
<input name="referralsphone" id="phone"....
change all these cases to:
<input name="phone" id="phone"....
<input name="referralsphone" id="referralsphone"....
I would also suggest checking the contents of POST. this question shows how Echo an $_POST in PHP
