(temporarily) save data to cookie or session

[ub.ch]

Heya!

I built a plugin with a search in it, which I want to paginate.
The easiest way in my mind was to save the search term(s) either into a session or a cookie and then, when page two is requested, do the search query again.

Now I can't seem to be able to access either cookies or session.
Tried using $_SESSION or $_COOKIE or vbsetsession() but to little avail it did not work

Any recommendations on how to properly do this?

Any help is really appreciated

ps: with "not working" I mean, that I can write to either, but after reloading the page, the information is no longer saved

A better way is to keep the search term in the URL (a $_GET parameter). Have you considered that?

[ub.ch]

Yep I have, but it is multiple keywords / checkboxes and I don't want to "clutter up" the URL that way

[Dave]

You could serialize those variables and put them in the URL in 1 parameter.
You could also base64_encode it.

yep I know I could do this, but don't want to
That would be the last resort; second to last would be to resend the form on every page change - but still, the question is: how can I use vbulletin sessions or cookies

[Dave]

Alright well in order to set a session variable, you can use $vbulletin->session->set('key', 'value');
For cookies you want to use vbsetcookie('key', 'value');

Thanks Dave!
How would I read them? Just using $_COOKIE / $_SESSION?

[Dave]

I believe you can use $vbulletin->session->vars['key'] to access the session variable.
You can just use $_COOKIE['key'] to access the cookie value.

This is a vB page? Then do it the proper vB way. https://vborg.vbsupport.ru/showthread.php?t=221670

mhh can't get both of them to work
I can save to the session, but refreshing the page yields no data.
Cookies are not working at all :/

I will have a look into it, still does not solve the problem I actually have.
I _don't_ want to have $_GET params; the page you linked to has actually no keywords or params to be searching for. Or am I missing something?

If I get it to work, I would still like to know how to save data to the session / cookie
