Magento issue with calling isInStock() method on a product
提问by Nick Dima
I want to check if some products are in stock but whatever I do the isInStock()method always returns TRUE. My products are configurable products with no associated products and under the "Inventory" tab "Stock Availability" is set to "Out of Stock".
What am I doing wrong?
Thanks!
我想检查某些产品是否有库存，但无论我做什么，该isInStock()方法总是返回TRUE. 我的产品是没有关联产品的可配置产品，在“库存”选项卡下，“库存可用性”设置为“缺货”。我究竟做错了什么？谢谢！

Magento has a lot of history at this point, so it's a good idea to not always trust that method names will do what "seems obvious". Obvious now wasn't obvious a few years ago.
Magento 在这一点上有很多历史，所以不要总是相信方法名称会做“看起来很明显”的事情是个好主意。现在明显在几年前并不明显。
If you look at the following two methods on the Mage_Catalog_Model_Product class
如果在 Mage_Catalog_Model_Product 类上查看以下两个方法
public function isInStock()
{
return $this->getStatus() == Mage_Catalog_Model_Product_Status::STATUS_ENABLED;
}
public function getStatus()
{
return $this->_getData('status');
}
You can see that isInStockchecks the statusattribute, set in the "General" section of the Product admin.
您可以看到isInStock检查状态属性，在产品管理的“常规”部分中设置。
Try this instead
试试这个
$stockItem = $product->getStockItem();
if($stockItem->getIsInStock())
{
//in stock!
}
else
{
//not in stock!
}

$qtyStock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product)->getQty();
回答by Bakk László
<?php if ((int) Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product)->getQty()>0) { ?>
<?php } else {} ?>
It worked for the simple product category view.
它适用于简单的产品类别视图。
