Ciao Denis, how to check if the current request plugin url is requested during the same session of the previous request?

I need to access the session, I guess... So I need the framework's singleton? Is there some way to check?

Maybe Yii::app()->getSession() ?

Permission ? Or just session ?

I test a lot if Survey session is set (with current id) to avoid some bad request.

gitlab.com/SondagesPro/QuestionSettingsT...ExtraSurvey.php#L593
App()->getSession()->get("survey_{$sid}") for example

I save plugin data in "survey_{$sid}" if i need to be resetted withn current survey or in my own session.

See gitlab.com/SondagesPro/QuestionSettingsT...sheetSurvey.php#L949

Session created during question view

Yes, you got it. I'm trying to add a controller who lets download answers in a custom PDF on the way (without saving it inside filesystem).
So I need to check the request is coming from the same client who answered before.
I've collected (sid+rid+seed) from afterSurveyComplete then I want to check that parameters with current session.

I've tried App()->getSession()->get("survey_{$sid}") but i get NULL value
Is it for 5.x LS? I'm still at 3.X

Session is resetted at end of submission.
After aftgerSurveyComplete

Then save right in you own session var :

gitlab.com/SondagesPro/ExportAndStats/pd...r/pdfReport.php#L444

Good point! I was forgotting about session expiration. So that I need to serialize my parameters inside a new session parameter and check for it inside the NewDirectController.
It's a very bad deal to pass them inside a GET parameter. Never do it.
