    <p>Im developing custom Joomla 2.5 backend component. I would like to know best practice of making variable global in my components scope. Should I put declarations in components main controller? </p> <pre><code>class MyController extends JController { /** * * @var object External database object */ public $dbExternal; function __construct($config = array()) { $this-&gt;dbExternal = $this-&gt;_getDbInstance(); JTable::setDbo($this-&gt;dbExternal); parent::__construct($config); } /** * Display task * * @return void */ function display($cachable = false, $urlparams = false) { // set default view if not set JRequest::setVar('view', JRequest::getCmd('view', 'My')); // call parent behavior parent::display($cachable); // Set the submenu MyHelper::addSubmenu('messages'); } /** * Getting instance of the database * * @return instance $dbExternal Return db instance on success */ private function _getDbInstance() { $params = $this-&gt;_getDbParams(); $dbExternal = JDatabase::getInstance($params); if ($dbExternal-&gt;getErrorNum() &gt; 0) { JError::raiseWarning(500, 'JDatabase::getInstance: '. $dbExternal-&gt;getErrorMsg()); $this-&gt;isError = true; } return $dbExternal; } /** * Getting external db parameters * * @return array $dbParamsArr Return db params on success */ private function _getDbParams() { $dbParamsArr = array(); $params = JComponentHelper::getParams('com_my'); $dbParamsArr['host'] = $params-&gt;get('db_host'); $dbParamsArr['user'] = $params-&gt;get('db_user'); $dbParamsArr['password'] = $params-&gt;get('db_password'); $dbParamsArr['database'] = $params-&gt;get('db_database'); $dbParamsArr['driver'] = $params-&gt;get('db_driver'); return $dbParamsArr; } } </code></pre> <p>So I would like to reach $dbExternal in any other components controller or model. Any ideas?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
