Is there a functionality for event handling in custom component development in joomla? I have searched all throughout and I only found about JEvents which was not exactly what I needed. My simple functionality is that when I select a value from 1st dropdown, a different list contents are displayed.

Also, does somebody have a complete reference for developing extensions in Joomla especially in Component Development?

I only have the Learning Joomla! 3 Extension Development 3rd Edition by Tim Plummer but it only discusses the basics in component development. I have some special cases in our development that cannot be found in the book. Since Joomla! 3 is only new, there are few references and mostly from lower versions.

  • Did you even look at joomla.org? There are tons of resources there...documentation, tutorials, communities. – GDP Dec 3 '14 at 2:07
  • Yes I did. I even have finished reading the articles for custom component development there. Almost all articles are incomplete. – Break the Law Dec 3 '14 at 2:14
  • Check this ,it may help.. – Jobin Jose Dec 3 '14 at 3:36
  • ^Jobin Jose, I have finished reading that tutorial. Almost all pages for version 3.x are blank, I have been relying on version 2.5 tutorials.. – Break the Law Dec 3 '14 at 5:47

Chaining Controls in a form is not a core feature. You have to introduce your own Javascript routines to conditionally show controls.

JEvent is oriented to support internal communication between a components and plugins.

To learn how to develop an extension, you can also check FOF:
