Hello,

I have a question about passing the argument via URL. I use Version 3.22.25+200706 of LimeSurvey


One of our users created a survey and add a question (List radio type) code like this:



Next, she adds attributes (1 and 2), nextly was added Survey participants finally activate the survey.


After a couple of hours of an active survey we observed the problem with responses and find out that problem is with variable passed via URL:


The problem was with SURVEY_IDXGROUP_IDXQUESTION_ID=SOME_VALUE

If we use this notation. Survey accepts only string/number with 5 characters, example:

https://SURVEY_URL/index.php/SURVEY_ID?lang=en&token=TOKENTOSURVEY&SURVEY_IDXGROUP_IDXQUESTION_ID=12345

https://SURVEY_URL/index.php/SURVEY_ID?lang=en&token=TOKENTOSURVEY&SURVEY_IDXGROUP_IDXQUESTION_ID=ABCDE

If we use a string with more characters this cause a problem:


But when I changed the URL and deleted SURVEY_ID and GROUP_ID. The survey works fine.


https://SURVEY_URL/index.php/SURVEY_ID?lang=en&token=TOKENTOSURVEY&QUESTION_ID=SOME_VALUE


This is confusing to me because I didn’t find any errors in the server log?


My question is how we should pass variables?

A) https://SURVEY_URL/index.php/SURVEY_ID?lang=en&token=TOKENTOSURVEY&SURVEY_IDXGROUP_IDXQUESTION_ID=12345

https://SURVEY_URL/index.php/SURVEY_ID?lang=en&token=TOKENTOSURVEY&QUESTION_ID=12345

C) https://SURVEY_URL/index.php/SURVEY_ID?lang=en&token=TOKENTOSURVEY (this also works for this survey)

D) Another way?

What are you trying to achieve with that URL parameter? You cannot be prefilling a survey question because the parameter is an invalid question code.

Good question,

In my opinion, this parameter isn't needed. Lime works fine with those URLs:

https://SURVEY_URL/index.php/SURVEY_ID?lang=en&token=TOKENTOSURVEY&QUESTION_ID=12345

https://SURVEY_URL/index.php/SURVEY_ID?lang=en&token=TOKENTOSURVEY

Just wondering why it works this way. It's bug or future?

As you do not want to use panel integration, in my opinion you should use:



Joffm

DevTools says -> Failed to load resource: the server responded with a status of 500 ()

What is your LimeSirvey version?

Since you can set anythiung in value to be prefilled : this muts not send a 500 error (maybe disable the value, but not a 500 error).

Version 3.22.25+200706

Confirm the issue about the 500 : bugs.limesurvey.org/view.php?id=16481

Else : you use a single choice question prefilled value by long string.

Understood! Thanks for confirming the bug
