Don't display stock counter for bundle products

My development website has a traffic light graphic system to illustrate stock levels for each item. In amongst those simple products, I have a few bundle products (more to come in future). On the product listings (and details) pages, the stock graphic is always showing red, or out of stock - even when every product contained in the bundle is IN stock.

I figure the only way around this is to hide the stock graphic for all bundle products.

Does anyone know how to do this? How do I perform a test in code to display (or not) the stock graphic based on the products type_id being bundle?

My worry is开发者_StackOverflow社区 that this isn't a great idea due to the added overhead of testing each product before displaying the page??

Any other suggestions are more than welcome! Cheers!

By looking at the default theme I see the bundle has it's own template for showing stock status which checks Mage_Bundle_Model_Product_Type::isSalable(), this already does the costly operation of loading all it's component products and checking them individually. Also the price works in a similar way, loading the components. It is costly because this is a big EAV operation. Some of the slowest stores I've worked on have notably had a lot of bundle/configurable products.

So the work is already done by the database and looping through the loaded products one more time to check the stock again will probably not be a big deal. Besides you can limit the impact by using something like CatalogCache.

Unfortunately I don't see a stock quantity event so you may have to extend Mage_Bundle_Model_Product_Type with your own getStockQty() method to do the appropriate lookups and calculation.

If you have already changed the stock display then it would have been in the template/bundle/catalog/product/view/type/bundle.phtml file. Remove the 'traffic lights' from there if you want the simplest way to hide bundle's stock level. This does not affect other product types.

It turns out this is far simpler than previously thought. The following code will check if a product is of type "Bundle" and then conditionally show the stock counter.

<?php if($_product->getTypeId() != "bundle"): ?>
[Stock counter display code here]
<?php endif; ?>

I hope that helps someone else looking for this!
