title: How can I pass the value of a hidden text field to another php page?
body: <p>I have a php page with the following:</p>
  
  <pre><code>echo "&lt;form method='post'&gt;&lt;input type='hidden' id='memberIdd' name='memberIdd' value=" . $memberId . "&gt;&lt;/form&gt;";
  </code></pre>
  
  <p>Now I created another php page and want to grab the value of this hidden field and place it into another variable. How can I do this? I tried using this for my second php page:</p>
  
  <pre><code>$member = $_POST['memberIdd'];
  </code></pre>
  
  <p>But I just keep getting "undefined" for $member.</p>
  
  <p>Thanks </p>
