Magento：如何在产品编辑器的描述中插入PHP调用

I have a the following code

<?php echo Mage::helper('stockstatus')->getListStatus(01); ?>

This code returns me the stock status of a specific product. It works great when i insert it in a .phtml file in magento.

But i want to use it also in the description of a product. The thing is that it doesn't return me anything if i put this code in the description of a product. On the front end it just shows the actual code.

My question is how to make it work when inserting in the description editor of a product? Please help

I don't think there's really an ideal solution here - you could use str_replace in the .phtml file on some specific string like [[stock_status]].

$description = $_product->getDescription();
$description = str_replace('[[stock_status]]', Mage::helper('stockstatus')->getListStatus($_product->getId()), $description);

Problem with this though is that if you were to use the product description anywhere else you'd either keep having to do the string replace, or end up with these tags in your description.
