PAJAJ framework, it stands for (PHP Asynchronous Javascript and JSON).
PAJAJ framework, it stands for (PHP Asynchronous Javascript and JSON). It is a object oriented Ajax framework written in PHP5 for development of event driven PHP web applications. The framework follows 5 basic principles:

1. Simple:

You do not have to be an expert at PHP, HTML, JavaScript, and CSS to use the framework. You can do most, if not all, your coding in PHP, and the framework will generate HTML, CSS, and JavaScript for you. There are object for most of the HTML element, with method to manage common task, like updating the content of a Div or items in a forms Select pull down. A lot of the other frames include a simple example that is anything but simple. For my simple example I have been asked where the rest of the code is!

2. Develop how you want:

The framework supports 3 different development models: i. the developer develops the whole application and interface in PHP, since the framework knows about HTML elements you want to interact with, i.e. there are objects for Select, Div, Table with instances with unique IDs; it is easy to have the framework generate simple html and CSS for you. ii. A designer generate a pretty but dump page, and you then hook events to it to make it a real application (see Last Binding of Event below) iii. You design an interface as a template (example Smarty), and have the framework make html, CSS, Javascript that you pore into the template.

3. Event Driving:

I would rather have events delivered to the back-end, and decide there what actions to take then to write a lot of JavaScript in the front-end. What happens after an event?:

The front-end gather information about the state of the page
The back-end see if there is an event handler registered for this event
If there is a registered event handler, it is call with the information from step i.
After processing data is return back, if any, to page for processing:
When an event happens there are 3 action that can be taken:
Preprocessor Action: example setting a spinning hour glass gif, to tell the use that something is happening.
Postprocessor Action: do something standard with the data that comes back, like update a div.
Back-end delivers code to front-end: have the back-end tell the front-end what it want to do, or message the user.

4. Late Binding of Events:

The pages HTML does not need to changed event and there logic (event handlers) are bound at run time. So your wed designer could delivery a pretty, but dump from, and without changes to the HTML you can make it into a AJAX enabled application. This make for simpler markup and an easier separation of design and code.

5. Object Oriented:

There are not only objects for the Ajax plumbing, but for page elements that you are interacting with. The page element objects have method to make this interact easier to program.

What's New in This Release:

A number features were added to make managing pages easier.
A small templating engine that takes advantage of PAJAJ features, templating, and configuration options can be set through the config file.
A HTML object that wraps the page's features was included.
Styled elements that are like mini-widgets were added.
A Google map widget was added.
