  • Overview
    • Joomla Development Flow
    • Module Structure
    • API Overview
  • Joomla - MVC
    • MVC(t) - Model View Controller (template)
    • Controller - Sets up environment for the display
    • Model - Data interface
      • Generally to the database, but can ‘create’ data if necessary
    • View - Uses the model to get data to display
    • TTemplate - Override-able disaplay output
  • Modules
    • Linear code execution
    • VC(t) (no real model necessary)
    • Uses a ‘helper.php’ file for additional function calls
      • Can be model-like, but modules don’t have DB tables
    • Files:
      • mod_<modulename>.php and .xml
      • helpers/helper.php
      • tmpl/default.php
  • Module Parameters
  • Module - Entry Point
  • Module - Helper File
  • Module Template - Address
  • Module Template - Contact Form
  • Joomla API Overview
  • Joomla API
    • http://api.joomla.com
    • Left side, select “Joomla-Platform” package
    • Bookmark, cuddle up to, and love this page
    • “ Classes” describes
      • JFactory - Get instantiations of common classes
      • JRoute - Get URL for specific component/view/task
    • “ Application” describes
      • Every other Joomla function
  • JObject
    • All Joomla classes derived from (You should too)
    • Easy getter/setter methods
      • $obj->set(‘var’, ‘value’); // Set a variable
      • $obj->get(‘var’, ‘default’); // Get a value
      • $obj->def(‘var’, ‘default’); // Set a default
    • $obj->toString(); // Great for debugging - no print_r($obj) required!
  • JUser Object
    • $user = JFactory::getUser(); // logged in user
    • $user = JUser::getInstance($id);
    • $id = UID or username
    • Once fetched:
      • if ($user->guest)
      • $user->get(‘username’); //id, fullname, lastvisitDate, etc
      • It’s derived from JObject!
  • JFactory - Database
    • $dbo =& JFactory::getDBO(); // Get the database handle
    • Functions describe in JDatabase & JDatabaseMySQL(i)
    • $query = $dbo->getQuery(true); // New Query $query->select(‘id, username, email’); $query->from(‘#__users’); $query->where(‘username=’.$dbo->quote($username); // No shenanigans! $dbo->setQuery($query);
    • $user->dbo->loadObject(); // objectList, array, arrayList, result, etc
    • Can use InsertObject function (or raw SQL) to add rows to database
  • JText
    • Text translation from language files
    • JText::_(‘MOD_CONTACT_HIYA’);
    • Searches loaded language files in last loaded order
    • Searches for first, exact, upper case version
      • If found, use transation; If not, use text directly
    • To Include more langauge files:
      • $lang =& JFactory::getLanguage();
      • $lang->load(‘mod_contact’); // Add your extension
  • JRequest
    • JRequest::getVar(‘name’, ‘default’, ‘POST’);
    • Can be risky depending on use. Should use sanitized methods below
    • JRequest::getInt(‘name’, 4); // Integers only w/ default of 4
    • JRequest::getCmd(‘task’); // strips . /
    • JRequest::getString(‘name’); // No nasty HTML
