title: Textarea PHP post issue
body: <p>I have a PHP post problem with a textarea.  I've searched this site, and the suggested remedies involved pulling the textarea's ID, and making sure you are using htmlspecialchars.  I'm doing both, and I still can't figure out why it won't post the contents of my textarea.</p>
  
  <p>HTML</p>
  
  <pre><code>&lt;form method="post" action="email.php" name="contactform" id="contactform" class="form form-stacked c-form"&gt;
  &lt;input name="name" type="text" id="name" placeholder="Name" /&gt;
  &lt;input name="email" type="text" id="email" placeholder="E-mail" /&gt;
  &lt;textarea name="theTextArea" placeholder="Message"&gt;&lt;/textarea&gt;
  &lt;input type="submit" class="submit btn outline" id="submit" value="Send message" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>PHP</p>
  
  <pre><code>$realName = $name = $theMessage = $subject = $WHATmessage = "";
  
  if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $realName = test_input($_POST["name"]);
    $name = test_input($_POST["email"]);
    $theMessage = test_input($_POST["theTextArea"]);
  }
  function test_input($data) {
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    return $data;
  }
  
  $subject = 'SUPERGROUP Inquiry - ' . $realName . ' - [' .date("F j, Y, g:i a").']';
  $WHATmessage = $realName . ' is looking forward to hearing from us!'.PHP_EOL.'Their email is: '. $name .'!'.PHP_EOL.'They said: "'.$theMessage.'"';
  mail('hello@sprgrp.com', $subject, $WHATmessage ); 
  </code></pre>
