NOSCRIPT - Detecting JavaScript

[Anon]

Hello !

How can I see in php, if the user has enables JavaScript ? Of course you can check the browser, but this doesn't give
you any hint, if the user has disabled JavaScript.

I thought of something like:

<NOSCRIPT>
<?php
$NoScript = true;
?>
</NOSCRIPT>

Which doesn't work of course, because $NoScript is always set to 1.

Any ideas ?

sorry but i think you may have misunderstood the way php and javascript interact.

in your code you execute php inside <noscript> tags. this will not determine if noscript is true or not.

one way to do this would be for your first page to call a php image, as in

<script>
document.write("<img src=dummy.php height=1 width=1>");
</script>

where dummy.php sets a cookie, i.e.

setcookie("scriptenabled", 1);

in all other scripts on the site you can check for javascript on the browser by using the condition if ($scriptenabled)

e.g.

if ($scriptenabled)
{
echo "<script> alert ('hey this works');</script>";
}
else
{
echo "you dont have javascript";
}

hope this makes sense 😉
