Javascript? Php? css.... Redirection for Mobile devices and Tablets

Hello. I came to the conclusion that I am going to make a seperate version of my site for Iphones/Ipods/Blackberry/Android/Windows phone devices and Tablets. Well, and ofcourse regular desktop version. Now I was trying to decide if I should use Javascript to get the screen size and then redirect to a custom page for the mobile devices. But on the other hand, I plan on having some dynamic pages creeated for me.

My site partyprinceproductions.com will have pictures locked behind a login form. So basicallly, I will implement PHP in the coming month to lock the site after someone clicks on a thumbnail of an event. I offer event photography, and I have a general page which features the events I shot. Then they click on the event page that they would like to see pics for. And on that page it will have thumbnails of each pic. When they click on the thumbnail to view larger, thats when they will be required to login. I would like to somehow automate the process of uploading the pics, and have them watermarked, thumbnailed and have an event page created for it.......... Soooo aside from the thumbnailing, watermarking and page creation.... I want to get a grasp on what I am going to need to do. So that I can start rebuilding my site with the future in mind. Should I have Javascript redirect to a seperate site depending on screen size? Should I have it "pass" the info to PHP to serve the appropriate page? Should I just have PHP do it?

What are some tips you can give. Or even the slightest code examples would be appreciated. I am just trying to get an understanding, and all info appreciated. Thanx in advance.

 

You could use this PHP class that'll detect if they're on a mobile platform.

 

Wow. Thanx. This seems very good. But if I were to do this:

Then they would automatically send to the new version, which is great. But If I wanted to offer the user an option to view the regular desktop version, then what would I do?

 

And is this in the latest version of PHP? Have you tested? Just want something thats going to be solid. Solid across new and old android, new and old iphone, etc...

 

It works great. I used this class to a few projects, and everything is alright.

 

Cool. Thanx. Is that the only thing you use for Mobile sites? Do you do any tweeking? Or any additional Javascript redirection?
