Menu
I would like my PHP script to be able to access the width of the browser window. I've been reading up on this, and PHP can't access this information itself, but Javascript/jQuery can, and can then pass it to the server using AJAX, so PHP can get at it.
Following a few solutions online I've written the following test file, and called it "test.php"
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
</head>
<?php
if (!isset($_POST["window_width"])) {
?>
<script type="text/javascript">
var window_width = $(window).width();
$.ajax({
type: "POST",
data: "window_width="+window_width,
});
</script>
<?php
}
if(!isset($_POST["window_width"])) {
echo "not set";
}
?>
</html>
Loading test.php displays "not set" which shows that the window_width variable is not being picked up by PHP. This seems weird to me, because Firebug shows that the variable is there (set at 1366 on my computer, as this is the width of my browser).
How can I ensure that $_POST["window_width"] is set so that I can access it using PHP?

I dont understand whats you goal ist but it looks like you forgot to wait till the DOM is ready.
$(function() {
var window_width = $(window).width();
$.ajax({
type: "POST",
data: "window_width="+window_width,
});
});
