Question

对于prestashop 1.6我们已经为特定产品设置了购物车规则，通过添加3个产品，另外1个产品将作为礼物添加，

这在购物车页面上运作良好，

但如何在特定产品页面上显示

$context::$this->$cart->$getCartRules();

未在产品页面上显示

我们必须在具有受尊重购物车规则的特定产品上显示购物车规则，

ex. "buy this product and you will get xyz product for free"

Answer 1

我认为您必须构建自己的查询，选择带有仍然有效的gift_product标识的cart_rules。

在CartRule中添加一个静态方法（或者你需要的地方）并直接在product.tpl中调用并显示它

ex：{CartRule::getGifts($product.id)}然后，处理结果

Answer 2

为此构建自定义查询：

$result = Db::getInstance()->executeS('
            SELECT *,rg.quantity as minimum_quantity FROM `'._DB_PREFIX_.'cart_rule_product_rule_value` cv 
                LEFT JOIN `'._DB_PREFIX_.'cart_rule_product_rule` pr ON cv.id_product_rule = pr.id_product_rule 
                LEFT JOIN `'._DB_PREFIX_.'cart_rule_product_rule_group` rg ON pr.id_product_rule_group = rg.id_product_rule_group
                LEFT JOIN `'._DB_PREFIX_.'cart_rule` cr ON cr.id_cart_rule = rg.id_cart_rule
                WHERE cv.id_item = '.$this->id_product.' AND cr.gift_product > 0 AND cr.date_to >= "'.date("Y-m-d H:i:s").'"'
            );

Answer 3

我在 Product.php

中的解决方案

 public function getRule($category = "0"){
   $rules = Db::getInstance()->executeS('SELECT *,rg.quantity as minimum_quantity FROM `'._DB_PREFIX_.'cart_rule_product_rule_value` cv 
            LEFT JOIN `'._DB_PREFIX_.'cart_rule_product_rule` pr ON cv.id_product_rule = pr.id_product_rule 
            LEFT JOIN `'._DB_PREFIX_.'cart_rule_product_rule_group` rg ON pr.id_product_rule_group = rg.id_product_rule_group
            LEFT JOIN `'._DB_PREFIX_.'cart_rule` cr ON cr.id_cart_rule = rg.id_cart_rule
            WHERE code = "" and ((cv.id_item = '.$this->id.' and type = "products") or (cv.id_item = '.$category.' and type = "categories")) AND cr.date_to >= "'.date("Y-m-d H:i:s").'"'
    );
    return $rules;
}
