I'm running a survey site that uses multiple surveys that a user completes over time - e.g. week 1 user registers, week 2 user completes Form1, week 3 user completes Form2.
I would like know if it's possible to carry data from Form1 in to Form2 so that when I view Form2 all the data from Form1 is visible, or alternatively link up the data in the two forms somehow. The forms have numerous fields, and while I know it's possible to do with URL variables it seems like a major hack - there would be up to 5 extra fields passed through and they are quite lengthy and also have open ended answers.
I'm currently looking at exporting the survey data to a CRM platform (so each form would add/write data to the user profile), but it seems like an unnecessary use of another system. I can use the users email or username as a consistent variable across the forms.
