Go Joomla 1.6 with your extension - Joomla!Days NL 2010 #jd10nl

How to get your
extension 1.6 ready
By Hannes Papenberg
Joomla! Release Manager

Do I need to change my extension?
Depends on the extension
All extensions need to update their language files
All extensions need to update their XML files
Extensions dependent on the old access system need to update

Language Changes
Why did we change this?
MASSIVE speed-improvement (50% faster)
What do you need to change?
Quote all values in the INIs
Keys should only contain Aa-Zz & 0-9
Quotes are escaped with „_QQ_“

XML Changes
JParameter is deprecated, JForm is the future
Replace all <params> with <fields>
Replace all <param> with <field>
Use <fieldset>

Access System Changes
Isn't that obvious? ;-)
Change your queries from 'access < '.$gid to 'access IN ('.implode(',',$user->authorisedLevels()).')'
Implement access.xml and $user->authorise()

Make a native 1.6 extension
Use JForm for forms
Use JDatabaseQuery
Change your component entry file
Use JCategories for your category system
Move your assets to the /media folder
Create semantic, table-less output

Forms with JForm
Used to create dynamic forms
Provides easy way to create and extend forms
Good example: Backend of com_weblinks

JDatabaseQuery
SQL Querybuilding class
Database abstraction layer
Be one step ahead, be 1.7 compatible
Syntax:
$query = $database->getQuery(true);
$query->select('*');
$query->from('#__table');
$query->where('id = 1');
$database->setQuery($query);

Component entry file
All classes used and invoked in the core are overrideable – except the component controllers
Instead of require_once(JPATH_COMPONENT.'/controller.php') use jimport('joomla.application.component.controller') and $controller = JController::getInstance('Componentname')

JCategories
Class to simply handle your components categories
Create a /helpers/categories.php file with the configuration options
Syntax:
$categories = Jcategories::getInstance('com_component');
$category = $categories->get($id);
$category->getChildren();
$category->getParent();

Assets in /media folder
Make it possible to move your extension from the webroot
Use <media>-tag in install file
Use API-functions to access them:
JHTML::image()
JHTML::stylesheet()
JHTML::script()

Semantic, table-less output
Ask Angie! ;-)
