Iluvatar+ Posted November 26, 2012 Share Posted November 26, 2012 You would have to use some AJax to do this. Quote Link to comment Share on other sites More sharing options...
Christian F. Posted November 26, 2012 Share Posted November 26, 2012 You don't need AJAX for this, a purely client-side Javascript is able to handle the request just fine. Theele: Write a JS that does the same as your PHP script, and then bind it to onchange on the input fields. You might want to check out jQuery for this, as it'll help make this a lot simpler than with just plain JS. Quote Link to comment Share on other sites More sharing options...
