Prestashop - PHP - 更新組合數量引發錯誤

Question

我正在嘗試創建一個 PHP 腳本來更新PrestaShop 1.6.1.11中組合的數量

我想我可以通過他們的代碼得到組合：

$product = new Product("COMB CODE");

$product->quantity = 5;  // your quantity
$product->save();

但是 PHP 提出：

PHP Deprecated:  array_key_exists(): Using array_key_exists() on objects is deprecated. Use isset() or property_exists() instead in /home/w.sk/web/Adapter/Adapter_EntityMapper.php on line 84
PHP Warning:  count(): Parameter must be an array or an object that implements Countable in /home/w.sk/web/classes/ObjectModel.php on line 478

您知道如何獲取現有組合並更新其數量嗎？

Answer 1

您可以使用此代碼更新組合數量：

$id_product = your product id
$id_product_attribute = your combination id
$quantity = your quantity
 
StockAvailable::setQuantity($id_product,$id_product_attribute, $quantity);

Answer 2

要添加到 Danoosh 的答案，如果您有產品的 ID，您可以執行以下操作：

$product = new Product($id_product);
$combinations = $product->getAttributeCombinations($id_lang, $groupByIdAttributeGroup); // 1, true for example

foreach ($combinations as $combination)
{
  $idAttribute = $combination['id_product_attribute']
  
  // product, id attribute (if simple product set to 0), quantity
  StockAvailable::setQuantity($product->id, $idAttribute, $quantity); // There is no need to save/update the product/combination
}
