Screen size....

NZ_Kiwis

I'm redesigning my site right now and are looking at making it for bigger screen but i want to add a script at the back of my site which will save the screen size of each visitor... i can add this to the DB fine but how can I get a visitors screen size??

You could possibly do something with JavaScript to get the current window size and send it via an AJAX request to a server-side script. But that would not tell you their screen resolution, just what size they currently have their browser set to. It might be more robust to default to a relatively "safe" size, then provide a link or two for the user to click if he wants the page displayed in a different resolution, saving their latest selection in the DB or a cookie.

OKay thats a new word... what/how??

Simply put, it's communications between JavaScript on the client side and server-side programs (such as PHP scripts). Asynchronous JavaScript And XML (though you don't necessarily need to use XML). There are several PHPBuilder.com articles at http://phpbuilder.com/columns/index.php3?cat=3&subcat=58, and Googling on "AJAX and PHP" ought to give you a few thousand matches. 🙂

You can use the 'screen' object in javascript to detect the user's screen size and resolution. You can then use js to manipulate the CSS based on the values detected.

Personally I recommend Prototype.js for all AJAX and also for DOM manipulation.
