Hi there, I would like to achieve the following: 1) A user fills in a CF form to subscribe for my service. A session variable is defined at this point for my user. 2) They are posted to the Paypal site where I use CF to pre-populate the customer details. 3) On successful payment, I need to direct them back to my success CF page with a variable (session or other passed in my originating form). 4) I then use this variable to process the purchase and update my database. I can't seem to see how I can get a variable back from Paypal but I can pass one to it (as a custom hidden field etc). Is the IPN my only solution? This doesn't seem to pass back the variable I need either? Can you please help? Cheers. Steve New Zealand

I can't figure out what the #Form.FieldNames# should be. I tried the same field names as my hidden input but....

Live well, laugh often, love much AND "Pay it forward"

Azriel - I am getting the same error as Ms Reba, and I have read the manuals until I am blue in the face - I cannot get this thing working no matter what I do, and it always comes ack with the error: Error resolving parameter FORM.FIELDNAMES on Line 20. I have tried just about EVERY sample code posted on this forum, as well as the sample code from PayPal's site.

I HAVE IPN enabled in my account as well...

There are alot of very frustrated people on these forums - all trying to get this thing working. The least PayPal could do is to post a better example script, or at least address the issues with the one they have posted.

Arg!

You want to pass the variable in the URL of the return page:
EX:

<cfhttpparam type="formfield" name="return" value="http://www.yourdomain.com/signupcomplete.cfm?user=#session.username#">

And this to your ipn 'notify' page:

<cfhttpparam type="formfield" name="notify_url" value="http://www.yourdomain.com/ipnpage.cfm?user=#session.username#">


Then on the page you have processing the IPN, declare somewhere in the code the url variable since the notify page will pass the url variable to that page, you will be able to use it:

<cfset Username = '#url.user#'>

Then query this against your db, and update the records based on that user.

You should of created the db records prior on your site when they created the account, perhaps on your signup page or whatever.

Send me an email if you need more help. I managed last year to get it working. I am currently creating a CFC that will do all the functions better, as I sometimes get errors.
