  <p>This is my PayPal form that I'm using for payment, on thank you page we add the code to get the response and update it on our system that the transaction is complete or not. </p>
  
  <p>we place this code on weburl.com/payment-processing/ that is our return URL </p>
  
  <p>$data=$_POST;</p>
  
  <pre><code>        if($_POST['payment_status']!=''){
          $item_name=$_POST['item_name'];
          $item_number=$_POST['item_number'];
          $txn_id=$_POST['txn_id'];
          $payer_email=$_POST['payer_email'];
          $payment_gross=$_POST['payment_gross'];
          $payment_status=$_POST['payment_status']; 
  
          $insert = mysql_query("INSERT INTO cr_payments(item_name,item_number,txn_id,payer_email,payment_gross,payment_status) VALUES('".$item_name."','".$item_number."','".$txn_id."','".$payer_email."','".$payment_gross."','".$payment_status."')") or die(mysql_error());
          global $wpdb;  
          $is_added = $wpdb-&gt;query("UPDATE cr_booking SET fld_booking_status = '$payment_status' WHERE fld_booking_id = '$item_number'");
