I cannot get any additional variables to be saved as part of a transaction from a Donation Button or Donation Link.
I am trying to pass some information into a donation transaction so it will show up on a PayPal Activity Report.
There are several fields that seem available to use for this purpose as they show up on a detailed Activity Report (such as "Campaign Name", "Item Details", "Custom Number" ,"Item ID", or "Subject"). It seems like there is a simple way to provide values into one of these fields would be using the "Add extra HTML button variables" option in the button creation tool.
However I get either errors in syntax that won't let me save them, or it will appear to save them but they are not there when I go to edit the button again.
I have seen some help postings that say there should be no code and I should just type in
item_name=membership or
item_name="membership"
and others that say the syntax should be more like this:
<input type="hidden" name="item_name" value="Membership">
However neither of those work.
What am I doing wrong (and why are there no syntax examples to reference within any of the documentation)?
I see that perhaps I am confusing valid HTML variables (like item_name) with variables that show up on an Activity Report, such as Item ID. But the bottom line is I want to put data into a transaction that will be visible on a report - I do not much care what the variable is named.
I would like to be able to create a distinction between a donation that is made for Membership, Tribute, or an Event. And ideally, have an additional level of granularity so each Event could have a unique ItemID or other value so that the many events can be distinguished from one another.
Any ideas on how to accomplish this would be greatly appreciated.
