title: How to POST form data from restored session?
body: <p>I use Firefox add-on called "Session Manager" to save and restore sessions. I have simple php + html form:</p>
  
  <pre><code>&lt;form id="form_id" enctype="multipart/form-data" method="post" action="upload.php"&gt;
      &lt;input id="name$key" type="text" placeholder="Name" name="name[]" value="$name"&gt;
      &lt;input type="file" name="fileToUpload[]" id="fileToUpload$key"&gt;
      &lt;input id="submit" name="submit" type="submit" value="Submit"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>When I restore form inputs data with "Session Manager" I can see all data I need. When I click the "Submit" button, data have empty <code>$_POST</code>. </p>
  
  <p>What can I do to not lose this data? </p>
  
  <p>Maybe to use some JQuery or <code>session_start(); $_SESSION</code>?</p>
