Question

我的最大问题是，当我选择产品的版本或更新数量时，我遇到了一个错误的ajax“在控制台中的控制台上，查询ajax的网址中参数令牌，id_product和id_customization都像这样重复：

https://xeof.com/index.php?controller=product?token=64c9f388aad0883a78f350addff907a8&id_product=81&id_customization=0&group%5B19%5D=291&qty=2&token=64c9f388aad0883a78f350addff907a8&id_product=119&id_customization=0&token=64c9f388aad0883a78f350addff907a8&id_product=74&id_customization=0

但这不是日志php错误中的全部，我有此错误：Undefined variable: find_best in G: \ Dropbox \ Sites \ xeof.com \ classes \ Product.php on line 6103

在该类中，调用方法是：

/**
 * Get an id_product_attribute by an id_product and one or more
 * id_attribute.
 *
 * e.g: id_product 8 with id_attribute 4 (size medium) and
 * id_attribute 5 (color blue) returns id_product_attribute 9 which
 * is the dress size medium and color blue.
 *
 * @param int $idProduct
 * @param int|int[] $idAttributes
 * @param bool $findBest
 * @return int
 * @throws PrestaShopException

public static function getIdProductAttributeByIdAttributes($idProduct, $idAttributes, $findBest = false)
{
    $idProduct = (int) $idProduct;
    if (!is_array($idAttributes) && is_numeric($idAttributes)) {
        $idAttributes = array((int) $idAttributes);
    }
    if (!is_array($idAttributes) || empty($idAttributes)) {
        throw new PrestaShopException(sprintf('Invalid parameter $idAttributes with value: "%s"', print_r($idAttributes, true)));
    }
    $idAttributesImploded = implode(',', array_map('intval', $idAttributes));
    $idProductAttribute =  Db::getInstance()->getValue('

    if ($idProductAttribute === false && $findBest) {
        //find the best possible combination
        //first we order $idAttributes by the group position
        $orderred = array();
        $result = Db::getInstance()->executeS('

                a.`id_attribute` IN (' . $idAttributesImploded . ')
            ORDER BY 
                g.`position` ASC'
        );
        foreach ($result as $row) {
            $orderred[] = $row['id_attribute'];
        }
        while ($idProductAttribute === false && count($orderred) > 0) {
            array_pop($orderred);
            $idProductAttribute =  Db::getInstance()->getValue('
                SELECT 
                    pac.`id_product_attribute`

                    `'._DB_PREFIX_.'product_attribute_combination` pac

    }
    if (empty($idProductAttribute)) {
        throw new PrestaShopObjectNotFoundException('Can not retrieve the id_product_attribute');
    }
    return $idProductAttribute;
}

我在第6103行中替换了这样的变量：之前：

如果（$ idProductAttribute === false && $ find_best）

之后：

if ($ idProductAttribute === false && $ findBest)

但没有运气，我有一个例外：

Can not retrieve the id_product_attribute at line 6143 in file classes / Product.php

我找不到解决方法！

我注意到，当我更改经典主题而不必更改php代码时，这些设置不会重复，并且我没有其他php错误。

Answer 1

更改此内容：

if ($ idProductAttribute === false && $ findBest)

收件人：

$findBest = true;

if ($ idProductAttribute === false && $ findBest)

Answer 2

在Prestashop 1.7.4上，我添加了这个override / classes / Products.php文件以解决AJAX调用期间的错误

// std::vector<T> being passed to std::bind
std::function<void(std::vector<int>)> funcA = std::bind(foo<int>,a);
myClass.addFunc( funcA );
myClass.caller(0)(a);  // Again std::vector<T> being passed but to `std::function`'s operator because the stored function requires this parameter.

现在组合可以正常使用
