Adding price and total column in shipping invoice in opencart

Question

Opencart by default doesn't show price and total in the print shipping at the admin side. So I added two more columns to the table in shipping invoice in order_shipping.tpl in admin/view/template/sale/order_shipping.tpl but I got the error as

Notice: Undefined variable: column_price in /home/blossewp/public_html/admin/view/template/sale/order_shipping.tpl on line 69 Notice: Undefined index: price in /home/blossewp/public_html/admin/view/template/sale/order_shipping.tpl on line 81

To me it seems the value is coming from the same controller order.php, I can't guess why then these variables are not visible inside order_shipping.tpl if they are visible in /home/blossewp/public_html/admin/view/template/sale/order_invoice.tpl.

Please help. The shipping invoice must have the price and total column.

Answer 1

The error is very clear

Notice: Undefined variable: column_price in /home/blossewp/public_html/admin/view/template/sale/order_shipping.tpl on line 69 Notice: Undefined index: price in /home/blossewp/public_html/admin/view/template/sale/order_shipping.tpl on line 81

It means that these variables are not defined, hence they are not passed from the controller to the view, the appropriate controller is located in <OC_ROOT>/admin/controller/sale/order.php , class ControllerSaleOrder @ function shipping() and I don't see your entries defined there

To solve the problem, just define them:
(1) Find $data['column_... = $this->language->get(... and add after $data['column_price'] = $this->language->get('column_price');
(2) Find $product_data[] = array( and add an entry 'price' => $product_info['price'], or $this->currency->format($product_info['price']) if you want to format it!

Answer 2

admin/controller/sale/order.php find :

public function shipping() {

and before

$data['orders'][] = array(

add

        $total_data = array();

    $totals = $this->model_sale_order->getOrderTotals($order_id);

    foreach ($totals as $total) {
        $total_data[] = array(
            'title' => $total['title'],
            'text'  => $this->currency->format($total['value'], $order_info['currency_code'], $order_info['currency_value'])
        );
    }

Then after

$data['orders'][] = array(

add

'total'            => $total_data,

Next step, open admin/view/template/sale/order_shipping and add

{% set last_total = order.total|last %}{{ last_total.text }}
