You’re welcome, Craig. Nowadays I don’t think that any user would benefit from turning JavaScript off, but I guess there would still be such users.

Thanks for this great bit of code. Very similar to how I was trying to achieve the same function, but much simpler.

Haven’t actually tested your version yet, but this could also use a session variable so that the script doesn’t have to be run every time a page loads.

Edit: the only downfall of using a session variable would be if a user turned javascript off after loading the page the first time. But of course there’s always a way around.

I know this is an old post but i will leave you guys the option that I used and worked on FF and IE, the only that i found was (i dont know if its good or bad) that the page blinks a lil bit, check it out:

” name=”jscheckform” method=”post”>

document.forms.jscheckform.jsenabled.value=”Y”;
document.forms.jscheckform.submit();

No JS”);
}
?>

i just included this file on every page and works fine to me, any comments will be apprecieated!

ciao!

fyi… I initially posted a comment critical of your statement that your PHP code wasn’t recognized in the noscript tag… but then I realized that you might not mean what I thought you meant. I thought you meant that the tag would influence the parsing of your PHP, which of course is not true. However, it seems that what you mean is that whatever you output within noscript will not be recognized by browsers with Javascript turned on… which of course is true.

It’s a good idea to use noscript when you can, though, because it’s designed for this very purpose. And in general, you can usually figure out ways to make a page downgrade gracefully without relying on more extreme solutions like automating a hidden form submission. To each their own, though, I guess :).

Hi Sid. Are you getting any errors in IE when you run the script?

@ derobonson:

you script will always give $js=1:

js: document.write([?php $js=1; ?]);

php will always process that line and set js to on — even when js is off… :(’

Thanks for the info above, i was playing around with some ideas and came up with the below, it seems to work fine and doesnt require hidden form fields or re-directions like other methods i have found.
