title: Module delivery/shipping prestashop
body: <p>I created a custom module delivery/carrier, but I need to pass the weight of products, the ZIP Code of delivery and the order value for the webservice. I am not succeeding in taking this information into my module.</p>
  
  <p>The following piece of code I'm using, actually, I'm following this example.</p>
  
  <p><a href="http://doc.prestashop.com/display/PS16/Creating+a+carrier+module" rel="nofollow">http://doc.prestashop.com/display/PS16/Creating+a+carrier+module</a></p>
  
  <pre><code>public function getOrderShippingCost($params, $shipping_cost)
  { //here i call my webservice }
  </code></pre>
  
  <p>I believe that this information is within $params, but do not know how to handle them or what they are.</p>
