Save a incoming url parameter as a session variable

Sun, 28 Jun 2020 20:44:16 +0000

I want a user to be able to filter out questions written in a specific language, and do it using an url-parameter when entering the site.

I am in qa-base.php accessing the url-parameter, but I can't seem to keep the variable value when I switch to some of the other pages. Trying with using session variable, but cant get it to work.

$thelang=qa_get('thelang'); // get from URL parameter if possible

if(isset($thelang)){

$_SESSION['thelang'] = $thelang;

echo "<br>Got GET Parameter!<br>";

} else { // get from SESSION variable

$thelang = $_SESSION['thelang']; // this part doesn't seem to work.

}

Thanks for any help! Maybe there is better ways to save the variable between pages.

Why is $userid not globally set?

Sat, 16 Apr 2016 06:57:40 +0000

I am seeing myself using

$userid = qa_get_logged_in_userid();

over and over again.

It would be easier to have this data "globally" accessible as $userid.

Is that possible?

How can I push the Q2A user role into a javascript variable?

I need to create some custom javascript that uses the user role.

I can easily get the user ID from mark-up..

var q2aUserID = $('.qa-user-link').text();

..but is there a way to push the user role (expert, editor, moderator, etc) into a JS variable?

Many thanks

How to put variable or function inside $this->output or html??

Tue, 10 Sep 2013 05:25:07 +0000

I am thinking this is probably a syntax error?. Basically all I want to do is put the search bar inside another div that is inside the login-bar div.

This is shortened version of the code

function body_header()

{

$this->output('<div id="qa-login-bar"><div id="qa-login-group">

$this->output ('

<div>

$this->search();

</div>

');

$this->output('</div></div>');

}

When I do this, I get a blank page. Any suggestions of what I'm doing wrong? t/y

Advanced Theme: How to set variable in one function and use it in another?

Fri, 22 Mar 2013 05:46:21 +0000

I am using an advanced theme to override two functions:

1. function main()

2. function q_view($q_view)

In main() I am also checking some user information, like is logged in and more! Then I set a boolean variable in main().

This boolean variable I need to access now from within q_view(), without doing all the queries again that I did in main().

How would you do that?

Thanks and have a good weekend,
Kai

Can I add a variable to the navigation tabs?

Sun, 23 May 2010 03:22:36 +0000

This might be a bit odd. Basically, I set up a chat room and have a tab that links to the chat in the nav in a custom theme.

I want to list how many people are in the chat in the tab. So the tab would say something like "Chat $Num_Active_Users" Where $Num_Active_Users is the number of people that are chatting. And don't worry, I already know how to get the variable. I'm just stumped on how to insert it into the tab.
