I figured out how to add a text input field option to a product

I've seen a couple of people looking for this feature so I just want to share it to anyone who wants it.
I've implemented this without making any database structure changes and just using the existing OpenCart administration pages.
It's a little corky the way it was implemented.
After a lot of trial and error, it came out to be quite a simple approach.
I'm just starting to learn PHP (was a VB programmer) and hopefully someone with better PHP skills than I can improve on it.
I tried, as much as possible, not to make too many changes to the existing code.

You can find a sample of the implementation in my test OpenCart shop.
Here's the link: http://www.veluzarwebdesign.com/shoptes ... oduct_id=8
You can have multiple text input box.

I'm in the process of testing it and will be greteful if anyone wants to help in testing.
If you are interested on how to implement it, send me a PM and I will send you the instructions on how to implement it when I'm done writing it, hopefully in a few days.  I have to "walk back" and track what changes I made.

Regards,
Troy
