一个产品在Magento 1.6.2无法更新库存项目数量(Cannot update Stock I

I am trying to update the stock quantities of products in Magento from within a script.

I load the product, set the stock quantity, and save - but the quantity remains unchanged.

// get stock data
$stockData = $product->getStockItem();
printf(PHP_EOL.'Stock: qty=%d, instock=%s, man_stock=%s, use_cfg_man_stock=%s'.PHP_EOL,
    $stockData->getData('qty'),
    $stockData->getData('is_in_stock'),
    $stockData->getData('manage_stock'),
    $stockData->getData('use_config_manage_stock')
);
// prints out qty=0, instock=, man_stock=, use_cfg_man_stock=


// $stockQty = 1
$product->stockItem->setData('qty', $stockQty);
$product->stockItem->setData('is_in_stock', $stockQty>0 ? 1 : 0);
$product->stockItem->setData('manage_stock', 1);
$product->stockItem->setData('use_config_manage_stock', 0);

$product->save();                           
$product->load();                           
$stockData = $product->getStockItem();
printf('New Stock: qty=%d, instock=%s, man_stock=%s, use_cfg_man_stock=%s'.PHP_EOL,
    $stockData->getData('qty'),
    $stockData->getData('is_in_stock'),
    $stockData->getData('manage_stock'),
    $stockData->getData('use_config_manage_stock')
);
// prints out qty=0, instock=, man_stock=, use_cfg_man_stock=

Where am I going wrong?

Answer 1:

所有你缺少的是节省$stockItem 。 你不应该需要创建一个新的stock_item也不应该有保存产品。

if (!($stockItem = $product->getStockItem())) {
    $stockItem = Mage::getModel('cataloginventory/stock_item');
    $stockItem->assignProduct($product)
              ->setData('stock_id', 1)
              ->setData('store_id', 1);
}
$stockItem->setData('qty', $stockQty)
          ->setData('is_in_stock', $stockQty > 0 ? 1 : 0)
          ->setData('manage_stock', 1)
          ->setData('use_config_manage_stock', 0)
          ->save();

Answer 2:

我已经解决了它自己：

// get stock data
$stockData = $product->getStockItem();
printf(PHP_EOL.'Stock: qty=%d, instock=%s, man_stock=%s, use_cfg_man_stock=%s'.PHP_EOL,
    $stockData->getData('qty'),
    $stockData->getData('is_in_stock'),
    $stockData->getData('manage_stock'),
    $stockData->getData('use_config_manage_stock')
);
// prints out qty=0, instock=, man_stock=, use_cfg_man_stock=


// $stockQty = 1
$stockItem = Mage::getModel('cataloginventory/stock_item');
$stockItem->assignProduct($product);
$stockItem->setData('is_in_stock', 1);
$stockItem->setData('stock_id', 1);
$stockItem->setData('store_id', 1);
$stockItem->setData('manage_stock', 0);
$stockItem->setData('use_config_manage_stock', 0);
$stockItem->setData('min_sale_qty', 0);
$stockItem->setData('use_config_min_sale_qty', 0);
$stockItem->setData('max_sale_qty', 1000);
$stockItem->setData('use_config_max_sale_qty', 0);
$stockItem->setData('qty', $stockQty);
$stockItem->save();

$product->save();                           
$product->load();                           
$stockData = $product->getStockItem();
printf('New Stock: qty=%d, instock=%s, man_stock=%s, use_cfg_man_stock=%s'.PHP_EOL,
    $stockData->getData('qty'),
    $stockData->getData('is_in_stock'),
    $stockData->getData('manage_stock'),
    $stockData->getData('use_config_manage_stock')
);
// prints out qty=1, instock=1, man_stock=0, use_cfg_man_stock=0

通过创建一个新的StockItem，并且将其赋值给产品。 希望这可以帮助别人。

Answer 3:

要显示库存数量的产品 -

 <?php echo $stock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product); ?>

如果你想显示个人数据使用本 -

<?php echo $stock->getQty(); ?> // Will display stock quantity
<?php echo $stock->getMinQty(); ?> // Will display minimum quantity
<?php echo $stock->getMinSaleQty(); ?> //will display minimum salable quantity

Answer 4:

在我来说，我买了，我已经编程进口产品同样的问题。 我才意识到，我忘了在阵列中添加stock_data ...

'name' => $productName,
'stock_data' => array(
                        'use_config_manage_stock' => 0,
                        'manage_stock' => 0,
                        'qty' => 0,
                        'stock_id' => 1,
                        'min_qty' => 0,
                    )

如果没有股票数据信息，Magento的产品添加到购物车产生了一个例外（在\ Mage_CatalogInventory_Model_Stock_Item）。

与此节点，它的工作原理。 =）
