Upgrade a Listing problem

[woolfie]

The program has a great feature that automatically calculates (based on a % value) the cost for a listing to be listed in extra categories.

Problem: This only works for a new listing.

My business model is to give free basic listings initially and to upgrade them when they see the benefit.

Problem: The Upgrade a Listing code calculates only the changes of period (time) and/or level (premium or sponsored) but not for increasing the number of categories.

Surely others would want or could benefit from this being a part of the program. I should think it would be an easy fix. After all, it is just making the "Upgrade a Listing" function exactly the same as the "Add a Listing" function.

Question: Can I copy the "Add a Listing" file and rename it "Upgrade a Listing" and then a few lines from the old "Upgrade a Listing" file (like existing category, etc. ) to get this needed capability? Or, does anyone have another MOD or solution they may have done for their site?

its not that easy as if you store the category when they submit the form then they may not complete payment. You need to store them temporarily until paypal says the transaction is ok then upgrade the links and add the categories, a little more coding is needed than jsut swapping for add listing code.

I think it needs fixing, as it is a little silly that it works in this way - somethign needs to be done on the modify form more than the upgrade form as you mentioned.
