选择付款方式时，opencart会在购物车中获得总价

Question

This is my custom payment method code for opencart:

<?php
class ControllerPaymentportmanat extends Controller {
    protected function index() {
        $this->data['button_confirm'] = $this->language->get('button_confirm_portmanat');

        $this->data['continue'] = $this->url->link('checkout/success');
        $this->data['order_id'] = $this->session->data['order_id'];

        if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/payment/portmanat.tpl')) {
            $this->template = $this->config->get('config_template') . '/template/payment/portmanat.tpl';
        } else {
            $this->template = 'default/template/payment/portmanat.tpl';
        }   

        $this->render();
    }

    public function confirm() {
        $this->load->model('checkout/order');

        $this->model_checkout_order->confirm($this->session->data['order_id'], $this->config->get('portmanat_order_status_id'));
    }
}
?>

How can I get current TOTAL size on my code? I want to define the TOTAL price on my code.

Answer 1

You can get the order info by using getOrder and using the order_id stored in the session:

$order_info = $this->model_checkout_order->getOrder($this->session->data['order_id']);

Now you can get the order total by using $order_info['total']
