This addon is meant as a replacement for the Product Attributes section in admin, for any version of oscommerce. The main advantages of it are:
Ability to add/edit/delete attributes quickly (very quickly).
A multi-select list that allows adding attributes to many products at once.
Ability to search attributes.
For those of you with a large number of attributes, you will probably be amazed at how quickly this responds when compared to the existing attributes code.
Please note that all of the sections are not completed. The basic attributes and search code is complete, I think, and the Options code is close to complete, if not complete. But the Values and Settings sections still need to be worked on. The old attributes section, or any addon for attributes that is installed, will still function so these unfinished parts won't cause any problems. I wanted to get it uploaded as it is now to start getting feedback on it to better know what to work on.
So if anyone tries it, please let me know of any problems, suggestions or questions.
