Kapitel 17
17.1 Beispiel zur Nutzung von JObject
$objekt = new JObject();
$objekt->set("eigenschaft","wert");
echo $objekt->get("eigenschaft") //gibt wert aus
echo $objekt->eigenschaft //gibt wert aus
$objekt->setError("Fehler aufgetreten");
$fehler = $objekt->getErrors(); //gibt ein Array der Fehler zurück
17.2 Direkter Aufruf der JMail Klasse mittels Konstruktor
$mail = new JMail();
$mail->addRecipient("test@example.com");
$mail->setSubject("Testmail");
$mail->send();
17.3 Erzeugung der Instanz über die Nutzung der Factory-Methode
$mail = JFactory::getMailer();
$mail->addRecipient("test@example.com");
$mail->setSubject("Testmail");
$mail->send();
17.4 Beispiel für die Nutzung der Klasse JDatabase
$db = JFactory::getDBO();
$query = "SELECT email FROM #__users WHERE username = 'admin'";
$db->setQuery($query);
$email = $db->loadResult();
17.5 Beispiel für die Nutzung von JDatabaseQuery
$db = JFactory::getDBO();
$query = $db->getQuery(true);
$query->select("email, username");
$query->from("#__users");
$db->setQuery((string)$query);
$users = $db->loadObjectList();
foreach($users as $user) {
echo ''.$user->username.'';
}
17.6 Beispiel für die Nutzung der JInput-Klasse
//Abfrage des Parameters id aus dem $_REQUEST Array
$input = JFactory::getApplication()->input;
$id = $input->get('id','0','INT');
//Abfrage des Parameters name aus dem $_POST Array
$input = JFactory::getApplication()->input;
$name = $input->post->get('name','','STRING');
17.7 Beispiel für die Nutzung der JInput-Klasse
$document = JFactory::getDocument();
$document->addStyleSheet("/media/com_jobs/jobs.css");
$document->setGenerator("Joomla 7.0");
17.8 Beispiel zur Nutzung der Klassen JFile und JFolder
jimport('joomla.filesystem.file');
jimport('joomla.filesystem.folder');
$path = JPATH_SITE."/images/";
if(JFolder::exists($path))
{
$files = JFolder::files($path);
foreach ($files as $file)
{
echo "Datei: ".$file." | Dateityp: ".JFile::getExt($file);
}
}
