Autoload the plugin, $autoload[‘plugin’] = array(‘widget’);
Create your widgets in a new application/widgets directory, and add a views subdirectory.
Widgets have access to the CI core and can load libraries themselves.
In your view call the static “run” method on the widget class:
<?php widget::run('user_login', (bool) $this->user->is_guest); ?>
