javascript variable to php

[hhoeksma]

Hi,

I am trying to put an output from JS into a variable I can use in PHP.

I figured the best way to do it was a form but I am not getting the hang of it completely...

Here is my code so far:

<form action="<? $_SELF; ?>" method="get">
<input type="hidden" name="scrw" value="javascript:document.write(window.innerWidth)"></input>

<input type="hidden" name="scrh">
    <script language=javascript>
    document.write(window.innerHeight);
    </script>
</input>

</form>  

<?
if(isset($_GET['scrw'])){
    $sw = $_GET['scrw'];
    echo "$sw";
    echo "x";
}
if(isset($_GET['scrh'])){
    $sh = $_GET['scrh'];
    echo "$sh";
}

?>

as you can see I tried two options, but both don't seem to work!

If there's someone out there able to giv'me a hand? That 'd be wonderfull!

I'm not positive, but your problem may lie in trying to use document.write. Usually, when I've used this function, it has written the data on a new page, but on the current page.
