title: Issue with multipart/form-data, ajax and textarea with TinyMCE
body: <p>I'm working with html/php/ajax/jquery and today I pointed out a little issue that is driving me crazy.</p>
  
  <p>I've got an html form:</p>
  
  <pre><code>&lt;form method="POST" enctype="multipart/form-data" name="myForm" id="myForm" action=""&gt;
      &lt;label class="form-label"&gt;Nome&lt;/label&gt;
      &lt;input name="nome" type="text" class="form-control"&gt;&lt;br&gt;
      &lt;label class="form-label"&gt;Descrizione&lt;/label&gt;
      &lt;textarea name="descrizione" id="text-editor" placeholder="" class="form-control" rows="10"&gt;&lt;/textarea&gt;
      &lt;label class="form-label"&gt;Stato&lt;/label&gt;
      &lt;select name="stato" id="source" style="width:30%"&gt;
          &lt;option value="1"&gt;Abilitato&lt;/option&gt;
          &lt;option value="0"&gt;Disabilitato&lt;/option&gt;
      &lt;/select&gt;
      &lt;h4&gt;Foto profilo&lt;/h4&gt;
      &lt;input type="hidden" name="MAX_FILE_SIZE" value="20400000" &gt;  
      &lt;input style="border:0px;" type="file" name="user_foto" id="file"&gt; 
      &lt;div class="form-actions"&gt;  
          &lt;div class="pull-right"&gt;
              &lt;button type="submit" class="btn btn-success btn-cons"&gt;&lt;i class="icon-ok"&gt;&lt;/i&gt;Inserisci&lt;/button&gt;
              &lt;button type="button" class="btn btn-white btn-cons" onclick="window.location.href='index.php'"&gt;Indietro&lt;/button&gt;&lt;/a&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I'm working with a JQuery+Ajax script that is able to fire a php script without reloading page, and insert form's data into a table in my database:</p>
  
  <pre><code>$(document).ready(function(){
      $('#myForm').on('submit',function(e) {
          var formData = new FormData(this);      
          $.ajax({
              url:'inserisciProfessionisti.php',
              data: formData,
              type:'POST',
              async: false,
              cache: false,
              contentType: false,
              processData: false,
              success:function(data){
                  window.location = 'listaProfessionisti.php'
              },
              error:function(data){}
          });
          e.preventDefault(); //=== To Avoid Page Refresh and Fire the Event "Click"===
      });
  });
  </code></pre>
  
  <p>Here my php code:</p>
  
  <pre><code>&lt;?php
  session_start();
  session_cache_limiter('nocache');
  if(!isset($_SESSION['mail'])){
      header("location:login.php");
  }
  include("include/connect.php");
  $conn=mysql_connect($HOST, $USER, $PASSWORD);
  $db_ok=mysql_select_db($DB, $conn);
  $nome=$_POST['nome'];
  $descrizione = $_POST['descrizione'];
  ....
  $comando="INSERT INTO professionisti('nome','descrizione',...)VALUES('$nome','$descrizione',...)";
  $ris=mysql_query($comando, $conn) or die("Errore connessione database: " . mysql_error());
  ... 
  </code></pre>
  
  <p>Everything works like a charm apart textarea content. It seems that textarea content wouldn't be passed to my php script.</p>
