In this third part of a series, I will show you how to build a revamped version of the image gallery created in earlier tutorials. This time it combines the functionality of Progressive Enhancement, Ajax and PHP to fetch images from the web server.
As youíll surely know, Progressive Enhancement (PE) is a powerful approach which, when used cleverly, allows you to develop more accessible and usable websites. Itís quite possible, however, that you have a solid background in the theoretical concepts that surround the application of PE, but still donít know how to use this paradigm in some practical, real-world situations. If thatís your situation, then I suggest you take a look at this article series. In its parts youíll learn how to take advantage of the benefits offered by PE when building some typical web programs, including dynamic image galleries and drop-down menus, form validators and Ajax-driven applications.
And now that you've been introduced to the main goal of this series, itís time to quickly review the topics that were discussed in the previous chapter. In that part of the series I developed a basic image gallery, whose behavioral layer (or in other words, the galleryís enhanced version) was implemented by using jQuery, which made implementation an extremely simple process.
Thatís precisely what I plan to demonstrate in this third episode of the series. This will give you another example that shows how to use PE in a realistic situation. Ready to learn how to combine PE, Ajax and PHP in one single web application? Then begin reading right now!
