JavaScript and PHP variables

[liamoco]

I am trying to get a JavaScript variable into a PHP variable, I can do this the other way around using the hidden input method and using something like var phpvar = document.getElementById('qwerty').value; to grab the PHP variable from within it. My problem is getting a JavaScript variable into a PHP variable, what methods are out there?

 

Thanks

if using a form, you can set the value of a form field via javascript and PHP will get it on submit. then there's ajax, allowing browser-to-server communication via javascript/php.
