magento - 检查产品是否存在

Question

我有一些使用 SKU 的 php 代码：

$sku = $id
$_product=Mage::getModel('catalog/product')->loadByAttribute('sku',$sku); //Get Product by ID (ASIN)
$qtyStock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product)->getQty(); //if in stock
$_prodcats = $_product->getCategoryIds(); 

如果 $sku 错误（在 $_product 行的数据库中找不到）我想添加到此代码中以便能够手动更改它，例如如果 $sku 不存在将其更改为 $sku = "909010";

感谢您的帮助

Answer 1

function get_product($sku){

$product=Mage::getModel('catalog/product')->loadByAttribute('sku',$sku); 
    if (!$product){
        $new_sku = '909010'; // If Real SKU doesn`t exsist, change to '909010'
        $product=Mage::getModel('catalog/product')->loadByAttribute('sku',$new_sku);
    }
    return $product;        
}

var_dump(get_product('your-sku')); // Real Sku 

Answer 2

$sku = $id
$_product=Mage::getModel('catalog/product')->loadByAttribute('sku',$sku); //Get Product by ID (ASIN)
if(!is_object($_product) || !$_product->getId()){
    //do your stuff here
}
$qtyStock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product)->getQty(); //if in stock
$_prodcats = $_product->getCategoryIds(); 

Answer 3

$sku = $id
$_product = Mage::getModel('catalog/product')->loadByAttribute('sku',$sku); //Get Product by ID (ASIN)

$_product = !empty($product) ? $product : Mage::getModel('catalog/product')->loadByAttribute('sku','YOUR-ERROR-SKU');

$qtyStock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product)->getQty(); //if in stock
$_prodcats = $_product->getCategoryIds();
