[Drupal] How to change a products shippable property during the Ubercart checkout process?

We may face a situation in our Drupal site utilizing Ubercart where we need to change the product shippable property during the checkout process. If a product can be shipped freely to certain locations we need to set the Shippable property to false programmatically in the Ubercart checkout process. Read on to know how to change a products shippable property during the Ubercart checkout process.

• This can be done by using a rules condition using the Drupal Rules module
• First we need to write a custom module with a rule file (that is modulename.rules.inc).
• Next we need to implement a hook_rules_condition_info in it and set whether the product is shippable or not in the function that we used to evaluate that condition.
• The following code will implement the hook_rules_condition_info, which will define a new rules condition in the rules admin page.
  

  /**
   * Implements hook_rules_condition_info().
   */
  function modulename_rules_condition_info() {
    $conditions['modulename_product_shippable'] = array(
      'label' => t("Check an order's product is shippable"),
      'group' => t('Modulename: group name'),
      'base' => 'modulename_product_shippable',
      'parameter' => array(
        'order' => array(
          'type' => 'uc_order',
          'label' => t('Order'),
        ),
      ),
    );
    return $conditions;
  }

• The following code will set whether the product is shippable or not
  

  /**
   * Checks wether this product is shippable or not.
   */
  function modulename_product_shippable($order) {
    $required_check = true;
    foreach ($order->products as $product) {
      if (check the condition whether this product need to be shippable or not) {
        //$required_check = false;
        $product->data['shippable'] = '0';
      }
      // To reset the pointer as per calling of end()
      reset($product->data['attributes']['Format']);
    }
    return $required_check;
  }
