Hello,
sometimes survey admins build long page forms and participants spend too much time responding (more than 5 minutes) that situation makes their session expires.
So that at the event clicking «next» (page) LS asks again for the token and forgets about last form fill.
People are very frustrated about that.

I would try to write a plugin who tries to update the session time at each form iteration (for example at each field focusing). The thing should send an ajax request useful for «pinging» they're still alive.

How do I can hook to the session and the fields elements in javascript?

This plugin already exist …

thanks to Frederik Prijck

Oh this is a great info, thank you Denis! Also thanks to Frederik.

A big heart to the community is absolutely needed in this situation

Thank you for this post!
I have the same problem. Currently I am working with the Community Edition Version 4.2. Unfortunately, the HeartBeat-plugin can not be installed in this version (it is not "compatible with this Version of LimeSurvey")

Therefore we also tried your advice from 4 years ago:

Setting the iSessionExpirationTime on a high value (our set session is set to DB in config.php.) But unfortunately this didn't work as well...

Is there any update of the HeartBeat-plugin compatible with the V4.X or another way to prevent time outs?

Best,
Michaela

Nobody ask me to update HearthBeat …
gitlab.com/SondagesPro/coreAndTools/HeartBeat/-/issues

I have some plugin than can not be updated due to issue in 4.X

Else : you can update tour php config
www.php.net/manual/en/session.configurat...ssion.gc-maxlifetime
and
www.php.net/manual/en/session.configurat...sion.cookie-lifetime

iSessionExpirationTime can be used only if you use DB session

Hi,
I tried to install it.
Therefore I added in the config.xml 4.2 and 4.3
and got this




You see, I just try.
Either it works or not.
If Yes, fine.
If No, well, same situation as before.
