Using OpenCart 2.0. How do I display customers email on a category page?

问题

I'm using OpenCart 2.0 and I'm trying to show a user email on a category page when a user is logged in. The code below I believe works for it to show a users email on the success.tpl. How can I display it on a category page? Thanks for your time.

IN: /catalog/controller/product/category.php

I HAVE THIS:

 $this->load->model('account/order');
    $order = $this->model_account_order->getOrder($this->session->data['order_id']);
    if($order) {
        $this->data['email'] = $order['email'];
    }

THEN IN:/catalog/view/theme/default/template/category.tpl

I HAVE THIS:

<?php if(!empty($email)) echo $email; ?>

回答1:

This is part of the core library. You don't need to look up an order if they're logged in, you just need to use

$this->customer->getEmail();

Note that in 2.0 you can't just echo this in a template, you need to assign this in the controller to the $data array and then use the value in the template. A quick hack to just add it to the template is to use

<?php
global $customer;
echo $customer->getEmail();
?>

but really isn't recommended
