title: WorldPay integration
body: <p>I am currently working a system whereby my users can pay for items that they have added to an order.</p>
  
  <p>The payment will be using Worldpay.</p>
  
  <p>I have a Worldpay account, but I am a little confused as to what steps I need to do next.</p>
  
  <p>I am using symfony and I have an order, with products associated to it. I have then created a 'Pay Now' link, which links to a <code>executePayment</code> action.</p>
  
  <p>What I'd really like, is for this to then take me to the hosted payment pages on Worldpay, pay for the order and then takes me back to my site to an <code>order success</code> page.</p>
  
  <p>Has anyone implemented WorldPay using symfony before?</p>
  
  <p>Thanks</p>
  
  <p>EDIT:</p>
  
  <p>So It seems, that I can have a form on the page where the <code>Pay Now</code> button is, but change it to a <code>&lt;input type="submit" /&gt;</code> and then post the details to <code>https://secure-test.wp3.rbsworldpay.com/wcc/purchase</code></p>
  
  <p>Is there some kind of callback functioanlity, to redirect me to a confirmation/failure page if the transaction was completed?</p>
  
  <p>Thanks</p>
