DESCRIPTION
One of the new feature since Joomla 3.2 is Rapid Application Development (RAD) framework. A Joomla component is a PHP/MySQL web application that uses Joomla's framework. You can build your components on Joomla's framework and Joomla will take care of the database connection, the design (using templates), access levels, forms (JForms), etc. Using Joomla's framework saves you a lot of work and development time. However, it can be even faster! Most Joomla components include the same functionality: In the front-end a list of records from the database hyperlinked to pages with details of each record individually. In the back-end the component list records from the database, with a link to a form where you can change the data and save. Using the Rapid Application Development Framework (also known as FOF (Framework On Framework)) allows you to develop a component with common functionality with far fewer lines of code. In this presentation, Peter shows how you can use Joomla's RAD to build a simple Joomla component to manage locations and categories and present those on the front-end to visitors on a Google Map. Contents: * The Basics of FOF * Programming a back-end component using FOF Note: It *is* possible to attend this session without attending Part 2: Front-end After this session you should have an idea what FOF is and how to create your own back-end component using FOF.

a) Introduction● Your own webapplication: programming everything from
scratch● PHP/MySQL/HTML/CSS/JavaScript
● Joomla component: Joomla = Framework● Data to/from database – Database object● Layout – Template● Rights Management – Access Control List (ACL)● MVC → template overrides● Plugins – hook into events in own component
Joomladay Deutschland 2014Joomladay Deutschland 2014
a) Functionality component back-end● Category list
● Display list of categories● New / Edit a category● Delete categories● Publish/unpublish categories
● Categorie form
● Display form of a category● Save a category
● List of items
● Display list of items● New / Edit an item● Delete item(s)● Publish/unpublish item(s)
● Item form
● Display form of an item● Save an item
Joomladay Deutschland 2014Joomladay Deutschland 2014
a) Functionality component front-end● Display list of categories
● Display a single category
● Display list of items
● Display single item
Joomladay Deutschland 2014Joomladay Deutschland 2014
b) Rapid Application Development (RAD)
Joomladay Deutschland 2014Joomladay Deutschland 2014
● Abstracting common code functionality● Conventions● Don’t Repeat Yourself (DRY)
● Nooku Framework ('Koowa') – Johan Janssens● Joomlatools extensies (DOCman), Anahita
● Framework on Framework – Nicholas Dionysopoulos● Basis of Akeeba Backup, Admin Tools etc
b) Software Development Framework
Joomladay Deutschland 2014Joomladay Deutschland 2014
Rapid Application Development (RAD)● RAD = Framework on Framework (since Joomla 3.2)
● Extension of Joomla! Platform, Not stand-aloneJoomla's MVC classes & similar to Joomla's MVC API
● Backwards compatibile● Less code → faster development & less bugs● Convention over configuration -> FOF convention
regarding naming of functions and database field names-> automatic (“automagic”) functionality
● Bootstrap, jQuery, JSON● Hierarchical MVC (HMCV) – display component views at
other places (other views, componenten, modules)
Joomladay Deutschland 2014Joomladay Deutschland 2014
RAD/ FOF/ F0F ?● FOF (F O F) – Akeeba etc● RAD – FOF implementation in Joomla > version 3.2● F0F (F zero F) – Fork of FOF
Joomladay Deutschland 2014Joomladay Deutschland 2014
c) Joomla Component with FOF
Joomladay Deutschland 2014Joomladay Deutschland 2014
c) Joomla Component with FOF● Development Environment
● Local web environment:(LAMP/XAMP/MAMP) + phpMyAdmin
● Joomla 3.3.x installation● Git (software version control) + github.com● IDE for PHP:
– Netbeans / Eclipse / PHPStorm / your ”weapon of choice”

Errors● IMHO Harder to detect than "regular" Joomla component!● Cache!!● Debug
● E.g. back-end error: “An error has occurred. 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ORDER BY node.lft' at line 4 SQL=SELECT node.id FROM jos_categories AS node, jos_categories AS parent WHERE node.lft BETWEEN parent.lft AND parent.rgt AND parent.id = ORDER BY node.lft”
can be caused by error in the front-end!Test: rename front-end com_db8locate temporary
● Front-end error:Notice: Undefined variable: form_class in /var/www/rad/libraries/fof/render/strapper.php on line 676
Test: rebuilt .xml files step-by-step● print_r($object) / echo $query / die(“stop here!”)
