use the smarty {php} {/php} tags to include php code within templates.

I don't think your product code is going to be so simple, remember the client can re-order the products in the category, reverse list them, disable certain products etc etc. Your code needs to take into account all of those, the product ID isn't static either, if the customer deletes a product it no longer exists on the database and that product ID will show a blank.

Also watch it doesnt affect the static catalog generation.
