possible?: force unique answer was created by Questler
Hello I am wondering if it is possible that I can force my users to give unique answers like their email.

I have a survey and in the end I ask for their telefone number. I want LS to give an error if the number already exists.
Is it possible without big hacking and coding?

Thanks

I guess that you need some JQuery for external validation.

To expand on Gabriel's reply - there is no method within LimeSurvey to check previous submissions. You will need to make an AJAX call to a remote PHP script that queries the database for previous responses.

also have a look to the token system, maybe it could solve your problem in a different way than forcing unique answer.

Hello all,


I expected a "Unique answers" toggle in the question fields... Found none. So I have thought of two things :

- Topic dates back from 4 years ago : maybe 3.x or 4.x fixed this issue is a non-obvious way ?

- @Questler : did you find a solution to your issue ? REx would be appreciated ^-^ Thanks in advance !

Hi all,

Btw, for Questler's question, a token field would seem OK. I haven't tested, so I can't say if it's really OK with their other constraints.

For my constraints, it cannot work, as I need to limit the scope of the email field. It should be nice to be able to validate a register field by regexp...

Hi,

Still the "state of art" answer.

Again,
do an ajax call and in a remote php script query the database either by direct access or maybe by the API.
