Opencart - 在 .tpl 中包含 .tpl
我正在使用 opencart 开源电子商务网站。我遇到的主要问题是当我尝试将面包屑分离到包含在每个 .tpl 文件中的单个文件中时。我尝试过使用基本的 PHP include 方法，尽管这不起作用。
回复 Jay 的回答：
我创建了一个新的面包屑控制器，用于呈现单独的面包屑模板文件。
<代码> class ControllerCommonBreadcrumb extends Controller {
public function index() {
if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/common/breadcrumbs.tpl')) {
$this->template = $this->config->get('config_template') . '/template/common/breadcrumbs.tpl';
} else {
$this->template = 'default/template/common/breadcrumbs.tpl';
}
$this->render();
}
}
?>
虽然这会导致错误：
Notice: Undefined variable: breadcrumbs
I am using the opencart open source e-commerce website. The main problem I am having is when I try to separate the breadcrumbs into a single file that I include inside each .tpl file. I have tried using the basic PHP include method although this does not work.
In Reply to Jay's answer:
I have created a new breadcrumbs controller that renders the separate breadcrumb template file.
<?php
class ControllerCommonBreadcrumb extends Controller {
public function index() {
if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/common/breadcrumbs.tpl')) {
$this->template = $this->config->get('config_template') . '/template/common/breadcrumbs.tpl';
} else {
$this->template = 'default/template/common/breadcrumbs.tpl';
}
$this->render();
}
}
?>
Although this causes the error:
Notice: Undefined variable: breadcrumbs

为此，您需要首先使用 $this->children 将面包屑模板设置为控制器操作的子项，然后用它回显面包屑。您还需要设置面包屑控制器的 id，以便您知道在模板中回显什么内容，
我个人只是将面包屑添加到 common/header.tpl 文件中，这要容易得多
To do this, you need to first set the breadcrumb template as a child of the controller action using $this->children, then echoing out the breadcrumbs with that. You will also need to set the id of the breadcrumb controller, so that you know what to echo in your template
Personally I would just add the breadcrumbs to the common/header.tpl file instead, it's far easier
