Compatability fix with Product Minimum & Maximum module

I ran into problems when I used this module with Product Minimum / Maximum ( http://drupal.org/project/uc_product_minmax ), in that when I tried to decrement or increment the contents of my cart, it only did it by one, which is not allowed if you must have multiples of more than 1 for a product. I've hacked the pictured cart module to work for me, and I share my 10 lines of code that fixes this issue. I haven't tested it on anything other than my site, so no guarantees that it will work.

in uc_pic_cart_block.module , replace the uc_pic_cart_block_updateproduct_submit() function (around line 200 onwards) with the following code.

/**
 * Implementation of submit function for update product forms.  
 *
 * @ingroup forms
 * @see uc_pic_cart_block_updateproduct_form()
 */
function uc_pic_cart_block_updateproduct_submit($form, &$form_state) {
  $module  = $form_state['values']['uc_pic_cart_block_updateform_module'];
  $id      = $form_state['values']['uc_pic_cart_block_updateform_nid'];
  $data    = unserialize($form_state['values']['uc_pic_cart_block_updateform_itemdata']);
  $count   = $form_state['values']['uc_pic_cart_block_updateform_count'];
  $adding  = $form_state['values']['uc_pic_cart_block_updateform_adding'];
  
  // Check for product minimum multiples, in which case add / subtract by multiple
  if (!$node) {
  $node = node_load($id);
  }
  if (!$node->pmin_multiple || $node->pmin_multiple != '') {
	if ($adding) {
		$adding = $node->pmin_multiple * $adding;
	}
	if ($count) {
		$count = $count - $node->pmin_multiple + 1;
	}
  }
  
  
  // Standart functions are the best way to update cart item :)
  if ($adding) {
    $kit_products = array();
    // Adding product kit elements with current attributes
    foreach ($data as $element) {
      if (is_object($element)) {
        if ($element->module == 'uc_product_kit') {
          $kit_products['products'][$element->nid]['nid'] = $element->nid;
          if (isset($element->data['attributes']) && !empty($element->data['attributes'])) {
            $kit_products['products'][$element->nid]['attributes'] = $element->data['attributes'];
          }
        }
      }
    }
	
	
	
    uc_cart_add_item($id, $adding, $data + $kit_products);
  }
  else {
    module_invoke($module, 'update_cart_item', $id, $data, $count);
  }
}
