Summary12073: Invalid argument supplied for foreach() warning SurveyRuntimeHelper.php line 1057
Description

I'm getting a warning saying Invalid argument supplied for foreach() in SurveyRuntimeHelper.php line 1057.

The code on this line reads: foreach ($_SESSION[$LEMsessid]['fieldarray'] as $key => $ia)

So I guess I'm running into a problem with the session. If I set debug to 0 in the config, the page loads, shows the question but not the possible answers.

Steps To Reproduce

Unfortunately I don't know how to "force" / reproduce the problem.

TagsNo tags attached.

Can you attach a 1-question sample survey, please?

Back-end or front-end?

I cannot see any error when I import and run that survey. Also I cannot see an error when I run the survey from the link you provided. Please check and let me know.

Yes I know, just sent you the 1 question survey since you asked for it :-) Anyway, this is why I wrote that I don't know how to reproduce / force the issue.

But there is an issue, and I guess it has to do with session variables which get lost (since $_SESSION[$LEMsessid]['fieldarray'] is suddenly undefined, see description).

Can you think of a situation, where this value is unset, but the session still alive?

Usually this happens if you change the survey in the adminstration and try to continue to test the old survey in the frontend.
