Errors, warnings and notices can be displayed from any component, module, plugin or template using the methods outlined below.
//Get a handle to the Joomla! application object
$app =& JFactory::getApplication();
//add a message to the message queue
$app->enqueueMessage( JText::_( 'Some error occurred' ), 'error' );
/** Alternatively, in PHP 5 */
JFactory::getApplication()->enqueueMessage( JText::_( 'Some error occurred' ), 'error' );The second argument to the enqueueMessage function is the type of the message. The default is 'message', but 'error' results in a different style for the message. The message will be displayed in place of a special jdoc:include statement in your template. Place the following in your template at the location where you want messages to appear.
<jdoc:include type="message" />Message[edit]

$app = JFactory::getApplication();
