My plan to create a PHP/MySQL implementation of my PhotoNotes script was completed sooner than expected thanks to the requests and encouragement I’ve received on the project page. This was the perfect opportunity for me to teach myself some AJAX: creating, updating, and deleting notes all happens without a page reload.

Better error handling is something I will work on in a future release. Right now, the user will not see any errors occurring from the PHP script. This is an area that needs to mature for AJAX in general. I skipped through a couple AJAX books at the book store and one didn’t even have the word “error” or “exception” in the table of contents!
