PHPBuilder.com has posted part four of their tutorial series looking at the powerful combination of Ajax and PHP. This time they focus on the integration of forms and Javascript to make more powerful, interactive input methods.

AJAX is a very powerful system which enables dynamic, constantly changing content on a page--without refreshing the page. This useful system does, however, have some limitations with current browsers. We will cover these limitations in this article, specifically those pertaining to how HTML Forms operate within AJAX dynamic content and what type of JavaScript can be used in AJAX-generated content.

They talk about the limitations HTML forms have and how to combat them with a little bit of Javascript through the creation of a simple script to pull data from a backend script into a div on the local page.
