  • Your PHP code on that page is long finished executing by the time the JavaScript runs client-side. – Brad Apr 25 '13 at 03:01

    @jonas, Solve what? You haven't posted your actual problem... just your attempt at fixing it. You're asking the wrong questions. You didn't even tell us what you are trying to do. – Brad Apr 25 '13 at 03:28

Not the way your code sample is structured, no. PHP is a server-side language and Javascript is a client-side language. PHP is out of scope by the time any client-side script executes.

If you need to pass an object from the browser to your server you can use XMLHttpRequest (commonly referred to as AJAX).

  • @JonasFabriag - If you need the browser to pass data to your server, you have two options: having the user submit a `
    ` or use AJAX. There are a plethora of examples of how to do this on StackOverflow. Here is one that might get you started: http://stackoverflow.com/questions/5004233/jquery-ajax-post-example

To send a Javascript variable back to PHP, you need to do an AJAX request:

<script language="javascript" >
xmlhttp.open("GET","getvalue.php?id="+id,true);
xmlhttp.send();
</script>

And in getvalue.php you'd have:

<?php
$getthevalueofid = $_GET['id'];
?>

No way to do this. Use Ajax to pass javascript variable to php
