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 $application = JFactory::getApplication(); // Add a message to the message queue $application->enqueueMessage(JText::_('SOME_ERROR_OCCURED'), 'error'); /** Alternatively you may use chaining */ JFactory::getApplication()->enqueueMessage(JText::_('SOME_ERROR_OCCURED'), '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
Message
JFactory::getApplication()->enqueueMessage('Message');
Notice
Notice
JError::raiseNotice( 100, 'Notice' );
Warning
Warning
JError::raiseWarning( 100, 'Warning' );
Error
JError::raiseError( 4711, 'A severe error occurred' );
Joomla! 3.x and the Bootstrap template
Since Joomla! 
will use the bootstrap template, the messages will use the standard boostrap css styles for Alerts.
See: http://twitter.github.com/bootstrap/components.html#alerts
The general syntax remains:
JFactory::getApplication()->enqueueMessage('Your Message', 'type);
Where type can be one of
- EMPTY - yellow
- 'info' - blue
- 'error' - red
- 'success' - green
