Show stock for configurable product

Question

I have this code:

<?php if($_product->isSaleable()): ?>
    <p><?php echo $this->__('In stock:') ?>
    <?=(int)Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product)->getQty() ?>
    <?php echo $this->__(' stk.') ?></p>
<?php endif; ?> 

It works great for simple products, shows how many left.

But i also use configurable products. How can I get the code to get the stock of the simple product when the parent is a configurable? Now it shows 0.

Answer 1

Use the following for all types of products in order to check the stock:

if ($_product->getTypeInstance(true)->isSalable($_product)) {

}

Haven't checked but you can try this as well:

if ($_product->isAvailable()) {

}

Answer 2

As each option of configurable product has its own stock it is not possible to tell how much is left until visitor selects one (or more if more then one is configured).

Answer 3

In case anyone is still looking for the answer, I use this code in CE 1.9 to determine if there are 2 or fewer items left in stock and display a message. It sounds like you would be interested in displaying the value of $stock for each iteration of the loop along with the option title...

if($_product->getTypeId() == "configurable"):
    foreach ($_product->getTypeInstance(true)->getUsedProducts(null, $_product) as $simple) {
        $stock = (int)Mage::getModel('cataloginventory/stock_item')->loadByProduct($simple)->getQty();
            $ttlStock = $ttlStock + $stock;
    }
    if ($ttlStock <= 2 && $ttlStock > 0) {
        echo '<div class="onlyLeft">Only ' . $ttlStock . ' left!</div>';
    }
endif;

Answer 4

Go to Inventory Tab, and select "No" for Manage stock in the configurable listing.
