create session with jquery?

Question

is it possible to create session variables with jquery or javascript or do i have to use ajax to call a php that does that?

Answer 1

You'll need to use a server-request. Javascript operates only on the client, and session data is stored on the server.

// example of passing variable 'name' to server-script for session-data-storage
$.post("createSession.php", {"name":"jonathan"}, function(results) {
  alert(results); // alerts 'Updated'
});

And on the server, something like:

session_start();
$_SESSION["name"] = $_POST["name"];
print "Updated"; // What will be passed to Javascript "alert" command.

Answer 2

You can just use php to create a session variable, no javascript required.

<?php
session_start();  
$_SESSION['uniquely'] = microtime(true);
?>

I suppose if you wanted to create a session when a user hovered over an image, or clicked on a link, you could use jquery to make an ajax call to set the session.
