You can not assign client side variable(Javascript) to server side variable(PHP).
You have to use ajax to do this.
<script>
function assignJsValueToPHPSession()
{
var jsVar = 1;
$.ajax({
type:post,
url: "test.html",
data: 'sessionjsvar=' + jsVar,
success: function(){
$(this).addClass("done");
}
});
}
test.php
<?php
$_SESSION['phpvalue'] = $_POST['sessionjsvar'];
?>

You can set cookie using javascript and the same cookie will be accessible in server side variable(PHP).
$.cookie("name1", "test"); // emample 1
$.cookie("name1", "test", { expires: 7 }); // emample 2
$.cookie("name1", "test", { path: '/User', expires: 7 }); // emample 3
Get a cookie
alert( $.cookie("test") );
//In PHP
<?php
print_r($_COOKIE);
print)r($_REQUEST);
?>

$_SESSION['id'] = $_GET['c']
set the GET parameter you sent to a session variable.

Ya..i put $_SESSION['id'] = $_GET['c'];and in another page i have retrive this value..if(isset($_SESSION['id'])) {$g['client_id']=$SESSION['id'];}..but it doesn't enters to the if condition.

Did you use
session_start() on top of both the pages?Sujit Agarwal
Check if the JS code is being able to send the data properly, and verify by
echoing the SESSION variable just after assigning.Sujit Agarwal
ohk, welcome. now you can mark the most useful answer as correct by ticking the small tickmark on the left.
$_SESSION['id'] = $_GET['c']
Just check c is really in the URL first.

I think it's actually $_GET['c'] no?
