Old notes - needs updating

Getting started

First of all, read xajax 10 minutes tutorial.

To use ajax in tiki:

In php file, after including tiki-setup.php:

this will import xajax and declare in global scope $ajaxlib, an instance of TikiAjax, that's an extension of xajax class.

Before calling $smarty->display("tiki.tpl"):

you don't need to worry about assigning getJavaScript() to smarty or any client-side declaration, everything is already handled by tiki.

To declare and register ajax functions in server, create a php file in lib/feature called feature-ajax.php. In this file, declare the functions and register them with $ajaxlib->registerFunction(). If you need a javascript file, create file lib/feature/feature-ajax.js to hold these functions.

Ajax development guidelines

Ajax applications don't work for everybody. It breaks accessibility, don't work with some alternative or old browsers. Considering that, tiki ajax development guidelines aim to:

1. keep it simple to preserve tiki funcionality and layout with and without ajax
2. avoid forking code

1 - Template-based common layout

The look & feel of a page must always be the same with or without ajax, and defined by template. Changing the template should change both modes at once as long as html element ids are preserved.

2 - Load content statically first time

If you are delivering empty containers with smarty and then have a document.onLoad() to load data, then you're likely to be breaking directive #1. Load content as if there was no ajax, and then when user request more content you update html element's properties.

Tutorial - make a region dynamic

1- Identify template component

find in your template the block of code that you want to be dynamic.

cut that code, paste in a new template ($includeFile in this example) and include inside an html element:

2- Change your tpl to use {ajax_href} block in links

Now, edit your template and change links like this:

to

where $includeFile is the template to be loaded, and $elementId is the id of element in which template will be loaded.

3- Modify php file to process requests

in beginning of php file, after tiki-setup.php, put:

and at end, before $smarty->display() or any output, register the templates you want to be loaded dynamically and process requests:

that's all!
