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::_('Random error occured'), 'error');
 
/** PHP 5 */
JFactory::getApplication()->enqueueMessage(JText::_('Random error occured'), 'error');

The second argument to the enqueueMessage()-function is the type of message. Default is 'message', but 'error' gives a different style message. Try other types as well, to see how that works. The api for the JApplication-object can be found at: JApplication API The error message will now be displayed if the message-tag is present in your template. The message-field is added with the following statement in your template:

<jdoc:include type="message" />
