Hi everyone,

I have two survey - one that collects data, which has an end URL to take participants to a second survey to fill in their details to claim reimbursement. They're separate so that we keep the data responses anonymous.

I'd like a way of checking that the participant has filled in the first survey (at least in part) when they fill in the second. Otherwise people might share the second survey link and try to claim the reimbursement without having done the "work".

So ideally, I'd just like a field in my second survey that says something like "yes" if they have come from the previous survey.

I think this is possible, using pre-filled answers, and so far I've added a question to my second survey that is set not to show. But then I got stuck because there's a lot of different advice. Please can someone help?

Thank you for your help

You can prefill questions with answers via the URL, when redirect to the second survey.
You have to decide with information should be transferred.
And how secure in terms of tricking the system the whole thing should be.

The reimbursement won't happened without anyone reading the second survey, right? So no automatic confirming of the claims.
You just want to reduce the risk that people ignore the first survey.

Please keep in mind that local law might not allow connecting information of these two surveys. Or that the claim can be made without answering the first survey.

How to prefill answers and transfer data via URL:
www.limesurvey.org/manual/URL_fields

I would transfer a respondent id (generated by the first survey) and a variable which set the hidden question in the second survey to a certain number. You than have to decide if the second survey should react if the first survey wasn't filled out.

But first get used to transfer information via URL and how to prefill questions.

Thanks Jelo!

Sorry to be an idiot but which bit should I be looking at to pass through the respondent ID? I've managed to do the hidden question variable I think.

Thanks for the warning too.

{SAVEDID}
SAVEDID is the id assigned to this particular submission,

It is just as unsecure to pass a "Yes" with the URL as just leaving the URL. People will just share the URL including the "YES" and there you go. So your problem persists.

I would not show the URL and use the redirect feature. And I would pass the {SAVEDID} as Jelo mentioned. Then you could check if the SAVEDID code saved in the second survey corresponds with a SAVEDID in the first survey. If you have one SAVEDID various times in the second survey, then you know that there is something "fishy".

BUT: In this case you could actually just put the personal data at the end of the survey, because by passing on the SAVEDID you could join the two database tables and you would be able to connect personal data with the response data.

Ah, I didn't think of that, thanks. What do you mean by not show the URL? I'm using the automatically redirect feature.

Just to triple check, so I just add ".php?var1={SAVEDID}" onto the URL to do this?

Thanks!

Yes, this would be the automatically redirect feature, so respondents don't have to click on the link to the second survey.

Hi all,

I've tried adding ".php?var1={SAVEDID}" onto the URL to do this, but when I download the data the IDs are different.

Please can someone let me know what I'm doing wrong or if there is another way I can do it?

Thanks,

Gemma

Which IDs are different? You will have to compare SAVE ID from the first survey with VAR1 from second survey. The SAVEID from the second survey is not relevant any more.

Sorry I completely misunderstood how that was meant to work. Although I don't have a VAR1 in my second survey when I download the data, was there something I should have done to add this?

Thanks,

Create a hidden question with var1 as the name.
And check the panel integration section in the survey settings.

Perfect, it works now, thank you
