How to call a check for a product class in Ubercart

Question

In the Ubercart D7 uc attribute module I am trying to run code on the fieldset attribute if the product is a specific product class in the module with an if statement.

This calls an if for payment received

      if ($op == 'update' && $order->order_status == 'payment_received' && $arg2 == 'completed') { 
// ... your code goes here 

}

How do I call it for a product class??

In uc_attributes module at

   function uc_attribute_uc_form_alter(&$form, &$form_state, $form_id) {
  //. other code of module's function... 
    $element[$key]['#type'] = 'fieldset';
    //    if (product class . ..) {
  // ... your code goes here

So that only the validate code runs on the field set if the product is the same product class

I have rest of the code largely ready to go

Answer 1

The node type is Ubercart class. Because, then you create a new class in /admin/store/products/classes it will create the new content type in /admin/structure/types So code will like next:

if ($op == 'update' && $order->order_status == 'payment_received' && $arg2 == 'completed') {
  if (is_array($order->products)) {
    foreach ($order->products as $product) {
      if ($product->type == 'SOMECLASS') {
         // DO something
      }
    }
  }
}

The function to use is:

uc_product_is_product($node)

This returns a boolean variable indicating whether the node is a product type.
