Pass $_GET value to web page loaded with jquery

I have a page that loads messages for a messaging system. This page loads external_content (another page) every second using AJAX. The conversation ID is stored in the URL, so my method of transferring it for use in external_content was very basic:

$got = $_GET['conversation_id'];
$_SESSION['id'] = $got;

However, there is a problem. When multiple conversations are open at the same time on someone's account, each time one resets the other does too (the session variable is reset), so I need to prevent that from happening.

Thus, I somehow need to pass this GET variable through to another page where I could not simply use $_GET['conversation_id'], but I need to do it in a way so that the variable can be set more than once. External_content is shown in a div, so I'm not sure about passing it along with $_POST or something.

Big n00bie. Please help.

I assume in the script that the ajax request is sent to is looking for $_SESSION['id']? And that's where your issue is when you have the multiple tabs open, they're all looking at the same variable.

So whenever you send that ajax request, attach the conversation_id 

$.get( "YOURSCRIPT.php", {
    convo_id: "<?= $_GET['conversation_id']; ?>",
});

And then in YOURSCRIPT.php, instead of grabbing $_SESSION['id'], you can grab $_GET['convo_id']

EDIT

@Dr. McKay's way is the same as what I've just said here. Sorry I missed that one.

When your user on focus textarea on the current page, you can trigger onfocus event to make an ajax call to set Session superglobal for current conversation id.

Are you saying that you need to pass the conversation ID in the Ajax request? To do that, add it to a script element as a variable in your page head.

<script>
var g_conversationID = "<?php echo $_GET['conversation_id']; ?>";
</script>

Then pass it in your request:

$.get("mypage.php", {"conversation_id": g_conversationID}, function(data) {
    // Handle content
});

You could potentially parse it out of the URL using JavaScript, but this method is generally easier.
