title: Getting order data paypal not working
body: <p>I worked with Paypal multiple time.  I create a button, redirect to proceed.php?order=order on success, and in proceed.php check if gross amount and payee email match database information.</p>
  
  <p>My code always look like :</p>
  
  <pre><code>    if ($_POST['payer_email'] &amp;&amp; $_GET["ordertr"]){
              // get paypal value and product it to fetch correct serial
              $ppemail = trim(mysqli_real_escape_string($con, htmlspecialchars($_POST['payer_email'], ENT_QUOTES, 'UTF-8')));
              $ordertr = trim(mysqli_real_escape_string($con, htmlspecialchars($_GET['ordertr'], ENT_QUOTES, 'UTF-8')));
              $gross = trim(mysqli_real_escape_string($con, htmlspecialchars($_POST['mc_gross'], ENT_QUOTES, 'UTF-8')));
          if ($gross == $actualprice){//price match}
              }
  </code></pre>
  
  <p>Sadly, it's not getting the POST data back from Paypal as it was before. Is that sadly possible that Paypal stoped sending POST data once user redirected to site? I always used this way instead IPN, and I saw there is PDT but I never used nor never switch on/off before getting POST data like it should.</p>
  
  <p>Any ideas whats wrong? </p>
