Hi All, user of LimeSurvey hosted here. We've used URL fields successfully, but so far we're lacking the ability to submit the survey via prefilled fields. The use case is an email campaign where recipients can click an image to submit their response, like this

The link to LimeSurvey therefore needs to include the prefilled values (no problem there) and also the instruction to submit the survey immediately, without loading of the survey page with prefilled fields.

The benefit of this approach is that in a single click the data is recorded -- no opportunity for drop outs, overlooking the submit button (on small screens) etc.

Is this possible?

If you need to use LimeSurvey to collect the data, I would direct them to a PHP page that loads a response via the API add_response() method.

- www.limesurvey.org/manual/RemoteControl_2_API
- api.limesurvey.org/classes/remotecontrol...#method_add_response

Here are a couple of examples:

- www.limesurvey.org/forum/installation-a-...-sent-via-rc2#163916
- www.limesurvey.org/forum/can-i-do-this-w...-add-response#162815

Very helpful, thanks!

In other words: If the submit button would be triggered via Javascript after loading the page, it would fit your requirement? BTW: What version of LimeSurvey is used?

I think the API would be cleaner and more robust than a JS solution to trigger the submit in LimeSurvey.

We're using LimeSurvey hosted (limequery.com). The JS method sounds like a potentially awkward workaround...

What do you mean by writing "cleaner"? The question "Is it robust?" comes to my mind by every workaround in LS. I often wonder that is works without too many complains from the client browser side. A server side scripting which would allow triggering events (e.g. submitting or sending emails) would be great. A autosubmitt-setting on groups/questions or a special redirector questiontype (which is currently done via quota workaround) might be a feature request.

Since LimeSurvey GmbH is betting on pure LS SaaS business the external script hosted somewhere else seems to be not suitable for many customers they are aiming for.

The version is shown at the bottom of the page.
Try to click on the version number. The newer versions offer more infos about the installation.

I realize that you have a dislike/distrust for all workarounds but I think that they are one if the reasons that LimeSurvey is so flexible.

My suggestion to use the API is a server-side solution.

Which comes from the first time using LimeSurvey with a workaround in the old days. Hidden field with random number wasn't hidden for some browsers. Respondents entered numbers in the random number field

I'm aware of that. The distinction here was inside or outside of LimeSurvey. Reducing dependency with outside scripts might be a reason too.

I second your reasoning with more robustness via API.
