title: How can get transaction details from paypal after successful payment
body: <p><br />
  My sent data to paypal is <br /></p>
  
  <pre><code>"https://www.paypal.com/cgi-bin/webscr/cmd=_cart&amp;upload=1&amp;business=seller.email@something.com&amp;currency_code=USD&amp;bn=BusinessName&amp;return=http://www.sellersite.com&amp;item_number_1=55&amp;item_name_1=battery&amp;amount_1=55&amp;quantity_1=2&amp;item_number_2=52&amp;item_name_2=bat&amp;amount_2=5&amp;quantity_2=3"
  </code></pre>
  
  <p>And I want to show those sent data(item number, item name,amount,quantity) and the paypal transaction id to the buyer on "http://www.sellersite.com" after successful payment. (Suppose, the seller has the merchant account with paypal and he would enter that paypal id into database from admin section of the website. So,I would not think about his paypal account settings, my job is just to create the environment for paypal payment for the seller.)
  <br /><br />
  If I write a script like</p>
  
  <pre><code>$T_ID=$_REQUEST['tx']; // or $T_ID=$_GET['tx']; **ref(tx):- "https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&amp;content_ID=developer/howto_html_paymentdatatransfer"
  
  $item=$_REQUEST['item_number_1']; // or $item=$_GET['item_number_1'];
  </code></pre>
  
  <p>Then would I get those data from paypal ?</p>
  
  <p>Please tell me.</p>
  
  <p>-Thanks.</p>
