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
$data['options'] = array();
foreach ($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']
);
}
我得到了
Undefined index: product_id in F:\xampp\htdocs\*\catalog\controller\extension\module\latest.php
在foreach
参数
$this->request->get['product_id'])
以上product_id
是Undefined
,有什么建议吗?
答案 0 :(得分:1)
以下是您需要替换的页面
