在Magento 2.1.0中打開產品頁面時出現異常

我已經安裝了Magento 2.1.0。我試圖在打開程序中的每個產品頁面之前更新庫存狀態。在Magento 2.1.0中打開產品頁面時出現異常

我用來更新股票代碼：

// has $sku and quantity of product now 
$stockItem = $this->_stockRegistry->getStockItemBySku($sku); 
if($quantity > 0){ 
    $stockItem->setQty($quantity); 
    $stockItem->setIsInStock(true); 
}else{ 
    $stockItem->setQty(0); 
    $stockItem->setIsInStock(false); 
} 
$this->_stockRegistry->updateStockItemBySku($sku, $stockItem);

我突然無法打開，因爲例外如下的產品頁面：
我不知道是否因爲更新產品庫存。

我不知道如何解決這個問題。
於是我找到的文件AbstractSource.php上線74

我更改代碼：

//if (isset($options[$value])) { 
    //return $options[$value]; 
//} 

// new code here 
if (isset($options['value'])) { 
    return $options['value']; 
}

現在我可以再次打開該產品...

但我有兩個問題：

如何解決以正確的方式解決這個問題/異常？我想我無法修改文件AbstractSource.php
是否還有其他問題，如果我使用代碼「$ option ['value']」？

非常感謝！

您收到的錯誤與產品頁面中的select元素沒有得到正確的選項值有關，或者您提供的值不是有效的選項值。從你的代碼，它似乎是從你如何使用setIsInStock。從magento代碼塊文檔，這應該是合法的，因爲setIsInStock採用bool或int。但從Magento核心代碼示例中，他們使用int。例如： setIsInStock(1)。你可以在這裏找到一個例子： https://github.com/magento/magento2/blob/2.1.0/dev/tests/api-functional/testsuite/Magento/ConfigurableProduct/Api/CartItemRepositoryTest.php#L220

所以我建議你從布爾改變參數整數：0爲false和1爲true。

讓我知道如果解決它。其次，我很好奇你爲什麼需要這樣做，擺在首位。

對不起，我得到了同樣的例外...如果我更改了代碼。 $ options ['value']回到$ options [$ value] –

我有另一個系統：庫存管理系統。 Magento Shop中的所有產品都需要從我的庫存管理系統中加載庫存信息。每次在Magento Shop打開產品頁面之前，第一步都是通過我的庫存管理系統的API加載庫存數量。 –

您可以暫時在74和75周圍放置一個try catch塊，並轉儲兩個變量$ value和$ options的值。 – davidumoh
