尝试在index()函数声明后直接在controller / information / information.PHP的顶部添加它,并将{ID}替换为您要密码保护的页面的ID(您可以从URL获取ID,或者如果你有SEO网址,来自管理部分).

if (isset($this->request->get['information_id']) && $this->request->get['information_id'] == '{ID}') {
    //If the information_id is PRovided and IT matches the ID you wish to protect
    if (!$this->customer->isLOGged()) {
        //If the customer is not logged in already,redirect them to the login page
        //Use $this->session->data['redirect'] to redirect them back to this page after logging in
        $this->session->data['redirect'] = $this->url->link('information/information','information_id=' . $this->request->get['information_id']);
        //Do the redirect
        $this->redirect($this->url->link('account/login','','SSL'));
    }
}

我假设信息页面在上面的例子中没有使用SSL,如果是的话你需要修改它.

如果你对这应该去哪里感到困惑,请看看controller / account / account.PHP – 我从那里获取了这些代码,并为特定的信息页面修改了它.
