Opencart 3获取最新产品视图中的产品选项

Question

我正在修改OpenCart默认主题，我想在最新的产品视图页面上获取产品选项。

我从产品视图页面复制了此代码：

{% if options %}
 <hr>
 <h3>{{ text_option }}</h3>

 {% for option in options %}

  {% if option.type == 'select' %}
  <div class="form-group{% if option.required %} required {% endif %}">
  <label class="control-label" for="input-option{{ option.product_option_id }}">{{ option.name }}</label>
  <select name="option[{{ option.product_option_id }}]" id="input-option{{ option.product_option_id }}" class="form-control">
  <option value="">{{ text_select }}</option>
  {% for option_value in option.product_option_value %}
  <option value="{{ option_value.product_option_value_id }}">{{ option_value.name }}
  {% if option_value.price %}
  ({{ option_value.price_prefix }}{{ option_value.price }})
   {% endif %} </option>
   {% endfor %}
  </select>
</div>
{% endfor %}
{% endif %}

我在catalog/controller/extention/module/latest.php中复制了这段代码

$data['options'] = array();

    foreach ($this->model_catalog_product->getProductOptions($this->request->get['product_id']) as $option) {
        $product_option_value_data = array();

        foreach ($option['product_option_value'] as $option_value) {
            if (!$option_value['subtract'] || ($option_value['quantity'] > 0)) {
                if ((($this->config->get('config_customer_price') && $this->customer->isLogged()) || !$this->config->get('config_customer_price')) && (float)$option_value['price']) {
                    $price = $this->currency->format($this->tax->calculate($option_value['price'], $product_info['tax_class_id'], $this->config->get('config_tax') ? 'P' : false), $this->session->data['currency']);
                } else {
                    $price = false;
                }

                $product_option_value_data[] = array(
                    'product_option_value_id' => $option_value['product_option_value_id'],
                    'option_value_id'         => $option_value['option_value_id'],
                    'name'                    => $option_value['name'],
                    'image'                   => $this->model_tool_image->resize($option_value['image'], 50, 50),
                    'price'                   => $price,
                    'price_prefix'            => $option_value['price_prefix']
                );
            }
        }

        $data['options'][] = array(
            'product_option_id'    => $option['product_option_id'],
            'product_option_value' => $product_option_value_data,
            'option_id'            => $option['option_id'],
            'name'                 => $option['name'],
            'type'                 => $option['type'],
            'value'                => $option['value'],
            'required'             => $option['required']
        );
    }

我明白了

 Undefined index: product_id in F:\xampp\htdocs\*\catalog\controller\extension\module\latest.php

在foreach参数中

$this->request->get['product_id'])

以上product_id是Undefined，有什么建议吗？
