title: Adding two products to cart with one click on the "Add to cart" button. Open Cart 1.5.5.1
body: <p>I have created <strong><em>configurator.tpl</em></strong> file (duplicate of <strong><em>product.tpl</em></strong> + some editing) in <strong><em>catalog/view/theme/theme-name/template/product/configurator.tpl</em></strong> in order to have 2 products at the same time on the product page. Also, I have created the controller file <strong><em>catalog/controller/product/configurator.php</em></strong> (duplicate of <strong><em>product.php</em></strong> + some editing). Everything it's OK. You can check <a href="http://www.bekinilab.ro/opncrt/index.php?route=product/configurator&amp;path=59&amp;product_id=50" rel="nofollow">here</a>.</p>
  
  <p>Now, I'm trying to add these 2 products to cart, clicking once the "Add to cart" button. Always these two products will be the same two (product_id=50 and product_id=51).<br>
  Do I have to modify "add to cart function", or maybe to call the function twice, once for each product_id? Any approach will be OK.</p>
  
  <p>I've found some valuable info <a href="http://forum.opencart.com/viewtopic.php?f=20&amp;t=91440" rel="nofollow">here</a> but I can't imagine the solution. Please help!</p>
