CiviCRM Community Forums (archive)

I currently use a custom data field to allow users to choose where their contributions will go from our main contribution page.  I would like to be able to use this same page but to default the value of the custom data field based on the URL. 

For example, our main page has dropdown options of None, Apples, Oranges, Pears.  The default on the "Support our Causes" page is None.  If a user has been on our "Support Oranges" site, I would like them to be able to click on "Contribute to Oranges" and go directly to our main donation page with the custom data field already set to "Oranges".

My assumption is that I can pass the value in the URL like &customdata4=Oranges.  Am I correct or is there another way of doing this without creating an entirely new donation page dedicated to Oranges?

Thanks in advance!
