The Daily WTF post for today bears mentioning if for nothing less than to show how to not do things. It has an interesting twist on the whole Ajax craze that's going on in the web today, and takes it to a really scary, pointless level.

You should definitely check out the code on this one - using evil() is bad enough, but passing code back to the PHP server like that is just wrong (and a huge security hole).

For those of you that have been following along, PHPBuilder.com has posted the third and final part of their "Using XML: A PHP Developer's Primer" series. Even if you haven't been keeping up, it's worth a look.

In this edition, they look at more advanced topics - a deeper look at Ajax and how to style the data you get back with XSL, both on the client and sever.

To start, they look at XSL - what it is, how it's used, and some code examples of both the XML and XSL structures to style XML data into a valid HTML page. Of course, you'll need the PHP extension to get this all working, so they step you through the installation/enabling of that as well.

They touch on other topics (like passing variables to a stylehseet and XSLT in Javascript) before getting to a simple XSLT and Ajax example - pulling book data and formating it with examples of both the PHP and Javascript sides.

DevArticles has posted part two of their "Sending Email with Ajax" series today, this time discussing the development of the client side of things.

Welcome to part two of the series “Sending email with AJAX.” In three parts, this series goes through the making of a simple web-based email application. It uses AJAX as the driving technology for fetching the files responsible for sending email from the server, as well as for adding and updating contacts.

Building on the previous part, they create a few more modules - an "email sender", "contact listing", "contact insertion", and a function to get things started - initializeEmailClient. The next part of the series will wrap things up, making the server side of things to actually do the work of sending the emails...
