Opencart Force login when see Cart Page?

问题

There are a number of pages that require a customer to log in to view them. How would I do this for the cart page /index.php?route=checkout/cart

回答1:

I think you mean you want to have a customer login if they go to the cart page correct? If so, here's how you do it. Open /catalog/controller/checkout/cart.php and find this line

public function index() {

Below this line, add the following code

    if (!$this->customer->isLogged()) {
        $this->session->data['redirect'] = $this->url->link('checkout/cart', '', 'SSL');

        $this->redirect($this->url->link('account/login', '', 'SSL')); 
    }

回答2:

for 2.xx, you need add response->redirect() instead of redirect()

like this

if (!$this->customer->isLogged()) {
        $this->session->data['redirect'] = $this->url->link('checkout/cart', '', 'SSL');

        $this->response->redirect($this->url->link('account/login', '', 'SSL')); 
    }
