RE: [PHP] Detecting JavaScript

this is a function that is BUILT-IN to HTML for the last few versions. <script> //some script here </script> <noscript> <meta http-equiv=refresh content='5;url=http://some.nonjavascripting.page'> </noscript> -- this will redirect non-javascript browsers to a non-javascript page.

The single most reliable way to do that would be to have a page that runs JavaScript. For instance, if the JavaScript executes, it redirects to your JavaScript enabled page, if not, the page does a refresh to a non JavaScript enabled page. <html><head><title>tester></title> <script language='JavaScript'> window.location('http://some.javascript.enabled.page'); </script> <meta http-equiv=refresh content='5;url=http://some.nonjavascripting.page'> </head> The trick would be a matter of timing, the JavaScript must successfully execute before the timer runs out on the refresh tag. You can of course get much fancier, changing the redirect based on the client information that PHP has available. PHP could effectively write the JavaScript to the page based on the known capabilities of the client. For instance the refresh tag is generally useless for browsers like Lynx, as is the JavaScript. Alternatively, you could (just supposing now...) have the first page do an instant refresh, using JavaScript to trigger a value in PHP. If the value is set, JavaScript was enabled, if it is not, JavaScript was turned off. But I've not tried it.
