X-Cart forums - Showing some calculation at checkout

Hi there,
can somebody help me, I'm pretty stuck here :-(

I tried to calculate processing time depending on items in cart and orders in status 'P' so I created a mod that extends cart class like this:

Code:

namespace XLite\Module\Dsy\ProcessingTime\View;



/**

 * Cart widget

 *

 */





abstract class Cart extends \XLite\View\Cart implements \XLite\Base\IDecorator

{



    /**

     * Returns Processing Time

     *

     * @return string

     */

    public function getProcessingTime()

    {

        $items = $this->getCart()->countQuantity();



        $time = ceil($items/5);



        $orders = \XLite\Core\Database::getRepo('XLite\Model\Order')

            ->createQueryBuilder('o')

            ->andWhere('o.shippingStatus  = :id')

            ->setParameter('id', '2')

            ->getResult();



        $openorders = count($orders);



        if ( $openorders > 0 )

        {

        $openorders = floor($openorders / 3);

        }

        $time = $time + $openorders;

        

        return $time;

    }

    

}

This works fine on cart page, where I added a twig like this:

theme_tweaker\customer\shopping_cart\parts\process ingtime.twig

Code:

{##

 # Shopping cart items block

 #

 # @ListChild (list="cart.children", weight="30")

 # @ListChild (list="checkout.cart", weight="30")

 #}

<div class="subtotal" style="text-align: right; padding-top: 45px;">

  <strong>{{ t('Expected delivery time in working days') }}: {{ this.getProcessingTime() }}</strong>

</div>

It shows up beneath subtotal, you can see in screenshot 1.

Then I wanted to add the same to FastLaneCheckout right beneath shipping methods so that customers can combine delivery time with processing time.

theme_tweaker\customer\modules\XC\FastLaneCheckout \sections\shipping\processingtime.twig

Code:

{##

 # Fastlane checkout processing time

 #

 # @ListChild (list="checkout_fastlane.sections.shipping.right", weight="20")

 #}



<div class="subtotal" style="text-align: right; padding-top: 45px;">

  <strong>{{ t('Expected delivery time in working days') }}: {{ this.cart.getProcessingTime() }}</strong>

</div>

I had to add .cart before getProcessingTime(), otherwise I got this error

Quote:

XLite [error] Trying to call undefined class method; class - "XLite\Controller\Customer\Checkout", function - "getProcessingTime"

But with this.cart.getProcessingTime() the error disappears and the page is shown correctly but the value of this.cart.getProcessingTime() is missing. (screenshot 2).

The function is there, but it won't return anything. I added var_dump at the beginning so I found out it won't even get called.

I'v been trying for hours and days. I tried different things: various listviews on that page, extending other classes like controller\customer\checkout and so on, but nothing. What am I missing?

I just learned about x-cart 5 file structure and twig templates, adding modules and redefining classes. I didn't read the whole developer manuals so I think it's just something real stupid that I did wrong. Do you have any suggestions?

Best regards,
Daisy
