在Opencart中的每个页面上显示所需的产品选项

Question

我们可以在opencart中创建自定义选项，并根据需要将这些选项与产品相关联。我想在每个页面上显示所需的产品选项，即类别，搜索结果，而不仅仅是在产品详细信息页面上。

Answer 1

您可以通过编辑这两个文件来显示类别中所需的选项：

文件：

catalog\controller\product\category.php

找：

$data['products'][] = array(

用。。。来代替：

$options = array();

foreach ($this->model_catalog_product->getProductOptions($result['product_id']) as $option) {
    if($option['required']){
        $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'], $result['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']
                );
            }
        }

        $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']
        );
    }
}

$data['products'][] = array(
    'options' => $options,

文件：

catalog\view\theme\default\template\product\category.twig

在for循环中的某处，或者找到：

<div class="button-group">

在它之前添加：

{% if product.options %}
<hr>

{% for option in product.options %}
{% if option.type == 'select' %}

    <option value="{{ option_value.product_option_value_id }}">{{ option_value.name }}
    {% if option_value.price %}

然后清除你的ocmod，vqmod和twig缓存并检查它。
