Is it possible to validate a question against ALL previous submissions either on the survey or in an xls / csv file on share drive?
I'm happy to add plugins and do some js (although I don't know much).
Basically I have a question where I use ReGeX to validate the answer to a format I want it in (ticket numbers). But I also want to validate them against previous submissions by all to make sure it is not a duplicate.
Not possible without external coding. LimeSurvey isn't currently offering a way to access other responses during conducting an interview. So external coding is needed to access the database directly.
