如何仅显示每个属性
How to show only per attribute
我正在尝试使用 PRESTASHOP 开一家眼镜店，但我遇到了一个问题。我在 产品和客户 table 中创建了 4 个新列（左眼屈光度、右眼屈光度、鼻梁长度、腿长), 在 tables.
中相同
我想做的是当商店加载产品时，比较这些变量，如果它们相同则显示产品。这是为了尝试过滤眼镜给客户，只给他看适合他的眼镜。
原查询是下一个：
$sql = 'SELECT p.*, product_shop.*, stock.out_of_stock, IFNULL(stock.quantity, 0) AS quantity'.(Combination::isFeatureActive() ? ', IFNULL(product_attribute_shop.id_product_attribute, 0) AS id_product_attribute,

pl.`available_later`, pl.`link_rewrite`, pl.`meta_description`, pl.`meta_keywords`, pl.`meta_title`, pl.`name`, image_shop.`id_image` id_image,
il.`legend` as legend, m.`name` AS manufacturer_name, cl.`name` AS category_default,

'.Product::sqlStock('p', 0).'
LEFT JOIN `'._DB_PREFIX_.'category_lang` cl
ON (product_shop.`id_category_default` = cl.`id_category`

LEFT JOIN `'._DB_PREFIX_.'product_lang` pl
ON (p.`id_product` = pl.`id_product`

LEFT JOIN `'._DB_PREFIX_.'image_lang` il

LEFT JOIN `'._DB_PREFIX_.'manufacturer` m

.($front ? ' AND product_shop.`visibility` IN ("both", "catalog")' : '')
.($id_supplier ? ' AND p.id_supplier = '.(int)$id_supplier : '');
我正在尝试修改它，但我不太清楚如何修改。因此，我做错了事。我已将下一个左连接添加到查询中。
LEFT JOIN `'._DB_PREFIX_.'product_attribute` pa ON pa.`id_product` = p.`id_product`
LEFT JOIN `'._DB_PREFIX_.'product_attribute_combination` pac ON pac.`id_product_attribute` = pa.`id_product_attribute`

LEFT JOIN `'._DB_PREFIX_.'attribute_group_lang` attr_group_lang ON attr_group_lang.`id_attribute_group` = attr.`id_attribute_group`
感谢您的任何建议。
编辑：
产品的新字段是 prestashop 中的功能（产品中没有 table），请原谅我的错误。
我放了prestashop的数据模型供你参考。

我现在正在尝试通过使用一个模块来实现这一点，所以我的模块的 php 文件有下一个代码。我已经按照 CategoryController.php 中的代码进行操作，但我不知道如何在不满足条件的情况下删除产品。

我建议采用不同的方法并为此使用模块。您将创建一个模块，该模块在安装时会创建一个 table_ 类似 customer_optics_data 的东西。 Table 结构可能如下所示：
CREATE TABLE `'._DB_PREFIX_.'customer_optics_data` (
`id_customer` int(10) UNSIGNED NOT NULL,
`left_eye_diopter` int(10) UNSIGNED NOT NULL,
`right_eye_diopter` int(10) UNSIGNED NOT NULL,
`bridge_length` decimal(20,6) NOT NULL DEFAULT '0.000000',
`leg_length` decimal(20,6) NOT NULL DEFAULT '0.000000'
) ENGINE='._MYSQL_ENGINE_.' DEFAULT CHARSET=utf8;
然后您的模块将挂接到 actionProductListOverride 挂钩，这就是您执行检查的地方：
public function hookActionProductListOverride($params)
{
$customer_settings = MyDiopterModuleHelperClass::getCustomerSettings($this->context->customer);
if ($customer_settings) {
$params['hookExecuted'] = true;
// Filter products here, you are now overriding the default
// functionality of CategoryController class.
// You can see blocklayered module for more details.
}
}
该模块将有一个助手 class MyDiopterModuleHelperClass 用于注册和获取数据 to/from customer_optics_data table。
这样您就不会覆盖核心，您的更新仍将正常运行，可能发生的最糟糕的事情是如果挂钩突然从 PrestaShop 的未来版本中删除，这是不太可能的。
该模块还将使用以下挂钩：
displayCustomerIdentityForm - 在 My Personal information 中显示附加字段。这是您的客户输入模块信息的地方。
actionObjectCustomerAddAfter - 在这里您可以从 $_POST 获取数据并将其保存在模块的 table
actionObjectCustomerUpdateAfter - 如果数据已被客户更改，您将在此处更新数据，或者如果由于某种原因数据不存在，则插入数据。
可选地，您也可以将模块挂接到
displayAdminCustomersForm - 在后台显示 customers 表单中的附加字段。
