我是prestashop 1.6开发的新手，我想创建一个模块，该模块允许根据产品的不同属性列出产品 示例：我们有两种颜色（黑色和蓝色）和两种尺寸（L，XL）的牛仔裤，该页面显示四种产品（黑色L，黑色XL，蓝色L，蓝色XL），如图所示 listing example
您能指导我成功完成此模块吗
答案 0 :(得分：1)
有一个付费模块可以完美实现这一目标：https://addons.prestashop.com/en/combinaisons-customization/31071-show-combinations-or-product-attributes-in-product-list.html
或者，您也可以重写Category类中存在的getProducts（）方法，并在Category控制器中对其进行调用。
以下是与PrestaShop 1.6.x版本兼容的基本示例：
class Category extends CategoryCore
{
public function getProducts($id_lang, $p, $n, $order_by = null, $order_way = null, $get_total = false, $active = true, $random = false, $random_number_products = 1, $check_access = true, Context $context = null)
{
if (!$context) {
$context = Context::getContext();
}
if ($check_access && !$this->checkAccess($context->customer->id)) {
return false;
}
$front = in_array($context->controller->controller_type, array('front', 'modulefront'));
$id_supplier = (int)Tools::getValue('id_supplier');
/** Return only the number of products */
if ($get_total) {
$sql = 'SELECT COUNT(cp.`id_product`) AS total
FROM `'._DB_PREFIX_.'product` p
'.Shop::addSqlAssociation('product', 'p').'
LEFT JOIN `'._DB_PREFIX_.'category_product` cp ON p.`id_product` = cp.`id_product`
LEFT JOIN `'._DB_PREFIX_.'product_attribute` pa ON pa.`id_product` = p.`id_product`
WHERE cp.`id_category` = '.(int)$this->id.
($front ? ' AND product_shop.`visibility` IN ("both", "catalog")' : '').
($active ? ' AND product_shop.`active` = 1' : '').
($id_supplier ? 'AND p.id_supplier = '.(int)$id_supplier : '');
return (int)Db::getInstance(_PS_USE_SQL_SLAVE_)->getValue($sql);
}
if ($p < 1) {
$p = 1;
}
/** Tools::strtolower is a fix for all modules which are now using lowercase values for 'orderBy' parameter */
$order_by = Validate::isOrderBy($order_by) ? Tools::strtolower($order_by) : 'position';
$order_way = Validate::isOrderWay($order_way) ? Tools::strtoupper($order_way) : 'ASC';
$order_by_prefix = false;
if ($order_by == 'id_product' || $order_by == 'date_add' || $order_by == 'date_upd') {
$order_by_prefix = 'p';

$order_by_prefix = 'pl';

$order_by_prefix = 'm';
$order_by = 'name';
} elseif ($order_by == 'position') {
$order_by_prefix = 'cp';
}
if ($order_by == 'price') {
$order_by = 'orderprice';
}
$nb_days_new_product = Configuration::get('PS_NB_DAYS_NEW_PRODUCT');
if (!Validate::isUnsignedInt($nb_days_new_product)) {
$nb_days_new_product = 20;
}
$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,

return Product::getProductsProperties($id_lang, $result);

}
这将显示每个产品可用的所有组合，并选择右封面图片和详细名称（例如“我的衣服（红色，M）”）。尽管这个示例并不完美，但分页和库存也必须进行调整，但是您明白了。
