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.
