I've done something similar by building a multidimensional array of categories and subcats in one query and then Loop thru this with a for each to build the category structure.
Categories table looks like this CatID | ParentID | CategoryName Array is $category_menu[$ParentID][$CatID] I'm sure there's a better way, but this seems to work OK. I will email code sample later [off-list]. I would be happy to share code with others as well. olinux --- Corey Eiseman <[EMAIL PROTECTED]> wrote: > Hi folks, I've got a question hopefully someone can > shed some light on for > me. > > I'm building an online store for a client, and one > of the things he wants is > to organize his products into categories and > subcategories.. not so unusual, > but the kicker is he wants to be able to associate a > subcategory with more > than one category. > > I was thinking that I should be able to easily > serialize an array of cat_IDs > and store it, but my concern is that this will > sacrifice a great deal of > flexibility when retrieving the data.
