Display error messages and notices

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_OCCURRED'), 'error');

/** Alternatively you may use chaining */
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

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 is bootstraped

Since Joomla! will use bootstraped templates, 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

Success

Note the new style in Joomla! 3 using the type success

Success

JFactory::getApplication()->enqueueMessage('Success', 'success');
