There and Back Again

A PHP GPL Practice Management System providing Medical Billing, Medical Accounts Recievable, Scheduling, Access Control, and EMR. This application is one of my main projects at Uversa. AJAX is used thoughout for Patient Search, and in the Admin module. Be sure to check out the Fee Schedule editor and the Superbill editor for examples of scrolling editable tables. JPSpan is used as the AJAX Toolkit.

Provides Cross Browser XMLHttpRequest based AJAX support, synchronous and asynchronous operation is supported. An object oriented api is offered to both JavaScript and PHP sides. Basic operation on the server side is provided by a server page where php objects you want to export are registered, this page is included in html pages with a client flag which generates proxy javascript classes with the same api as the php class (all class and method names are lowercase). Calls are made by creating an instance of the javascript class and then calling its methods. In async operation a callback class is specified when the instance is created, results are sent to methods with the same name as the called method. Provides complex datatype (multi-dimensional arrays and object) serialization and support for passing php errors to javascript, with configurable error handling on the javascript side.
