Carved in mystic runes upon the very living rock, the last words of wj of
comp.lang.php make plain:

No, but it's possible to detect it with Javascript; you can then pass
that information on to PHP. It's a two-step process, though. Your first
page is something like this:

<META HTTP-EQUIV=Refresh CONTENT="1; URL=jstest.php?js=no">

<SCRIPT TYPE="text/javascript">
location = "jstest.php?js=yes";
</SCRIPT>

<?php
//foo.php
$js = 1;
if (isset($_GET['js']) && $_GET['js']=='0')
$js = 0;
?>
<noscript>
<meta http-equiv="refresh" content="0,URL='foo.php?js=0'" />
</noscript>
<?php
echo $js;
//etc etc
?>

<noscript>
<meta http-equiv="refresh" content="0,URL='foo.php?js=0'" />
</noscript>

While this might work, it's no valid HTML (noscript is not allowed in
the document's head).

Yo wj,

Why not simply set a value to a hiddenfield
using a simple javscript-function?

If there is the expected value within
your POST-VARS after submit ...

Yes, this a good criticism:-) What about this one, which doesn't
rely on meta refresh as browsers could disable it.

<?php
//foo.php
$js = (isset($_GET['js']) && $_GET['js']=='1') ? 1 : 0;
if (!$js)
{
?>
<script>
window.location = "foo.php?js=1";
</script>
<?php
}

echo $js;
//etc etc
?>

Also, if form is allowed to check the JS, it will be much easier
as we can populate any variables on onSubmit event. Also, it could be
much easier to do that in web bug.
