I'm trying to make an extension that does the following:
- User clicks link in email
- Form loads, extracts the contact ID from the querystring (along with a checksum for security), and customises the form appropriately
- User submits form
- Changes are saved
- Form reloads, showing updated data
My problem comes at step 5, as the form no longer knows what the contact ID is. How can I pass the contact ID to this page? It's no longer in the querystring, and I can't find it anywhere...
Sorry if this is basic stuff - I've tried to figure it out from the existing profile code.
