如何解决如何在特色的标准基本模块上显示产品选项？

如何在 opencart 3 的标准（基本）模块中显示产品选项

我在文件中添加了代码：modification\catalog\controller\extension\module\featured.PHP

代码：

$options = array();
foreach ($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)) {
                $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),'quantity'                => $option_value['quantity'],'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']
        );
    }
}

还添加了：

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

对于文件中的输出：template\extension\module\featured.twig

在产品卡上添加代码：

{% if product.options %}
    {% for option in product.options %}

    {% if option.type == 'radio' %}
            <div class="groupOptionWrap {% if option.required %} required {% endif %}">
                {#<label class="control-label">
                    {{ option.name }}
                </label>#}
                <div id="input-option{{ option.product_option_id }}" class='groupOptionElements'>
                    {% for option_value in option.product_option_value %}
                        {% if option_value.quantity == "0" %}
                            <div class="groupOption groupOptiondisable">
                                {{ option_value.name }}
                            </div>
                        {% else %}
                            <div class="groupOption">
                                {{ option_value.name }}
                            </div>
                        {% endif %}
                    {% endfor %}
                </div>
            </div>
        {% endif %}
    {% endfor %}
{% endif %}

但是没用

这个mod的所有PHP代码：

            $data['out_of_stock_notify'] = $this->config->get('module_notify_when_available_notify');

        if ($data['products']) {
            return $this->load->view('extension/module/featured',$data);
        }
    }
}

解决方法

以下行没有意义，这里您只是将所有选项附加到 products 数组的末尾，而不会将属性 options 附加到任何产品

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

要么您必须按产品 ID 在 options 数组中对您的选项进行分组，要么通过遍历产品将选项设置为更正 product

  1. 将选项分组
<?php
    if (!isset($options[$result['product_id']])) $options[$result['product_id']] = [];
    
    $options[$result['product_id']][] = 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']
    );

然后您将 options 变量传递给视图，您可以通过执行以下操作访问 twig 中的选项

{% if options[product.id]|default([]) %}
    {% for option in options[product.id] %}
        {# do stuff #}
    {% endfor %}
{% endfor %}
  1. 为正确的产品分配选项
<?php
    foreach ($this->model_catalog_product->getProductOptions($result['product_id']) as $option) {
        $options = [];
        
        /** fetch options **/
        /** fetch options **/
        /** fetch options **/
        
        foreach($data['products'] as &$product) {
            if ($product['id'] == $result['product_id']) {
                $product['options'] = $options;
                break;
            }
        }
    }

执行此操作后，您确实可以像在当前代码段中那样访问选项

{% if product.options|default([]) %}
    {% for option in product.options %}
        {# do stuff #}
    {% endfor %}
{% endif %}

请注意，选项 2 纯粹是关于如何执行此操作的示例，因为您没有指定 $result 或 $data['products'] 的来源，我只是试了一下

编辑

正如您现在发布的完整代码一样，选择选项 2 将是更理想的解决方案。

在您发布的代码中，您正在填充 $data['products'] 数组 (#110)，这里您只需要附加您创建的 options 数组，例如 

$data['products'][] = array(
    'product_id'        => $product_info['product_id'],'quantity'          => $result['quantity'],'quantity'          => $product_info['quantity'],'quantity'          => isset($result['quantity']) ? $result['quantity'] : (isset($product_info['quantity']) ? $product_info['quantity'] : 1),'attribute_groups'  => $this->model_catalog_product->getProductAttributes($product_info['product_id']),'thumb'             => $image,'name'              => $product_info['name'],'description'       => utf8_substr(strip_tags(html_entity_decode($product_info['description'],ENT_QUOTES,'UTF-8')),$this->config->get('theme_' . $this->config->get('config_theme') . '_product_description_length')) . '..','price'             => $price,'special'           => $special,'specialSavings'    => $specialSavings,'tax'               => $tax,'rating'            => $rating,'href'              => $this->url->link('product/product','product_id=' . $product_info['product_id']),'options'           => $options,);
