Set your messages in a controller:

Because Yii intends to be integrated nicely with third-party libraries, it does not define any global functions. Everything in Yii needs to be addressed with full class name or object scopes. For example, to access the current user, we need to use Yii::app()->user; to access application parameters, we need Yii::app()->params['name']; and so on. While editors like textmate can help alleviate the problem of these lengthy typings, it is worthwhile to define global shortcut functions to some commonly used method calls. They will make the application code look cleaner.

There is a lot of confusion surrounding what is happening behind the scenes when you render a view.

Something a good application cant miss is documentation, and what would be better than some nice formatted HTML documentation that can be auto-generated from your code, we know several tools that already do this like phpDocumentor, but today we are introducing Yii Docs Generator which is a modification of the code that Yii itself uses to generate its documentation, thank phpnode for this wonderful work.

These features provide endless possibilities and unbelievable flexibility, but as current documentation does not give more than a few examples, it might be difficult to fully understand their internals and requirements.

The two most commonly-used base classes in most Yii applications are CController and CActiveRecord, each extended to your own particular models and controllers.

Often you'll need a form with two dropdowns, and one dropdown's values will be dependent on the value of the other dropdown. Using Yii's built-in AJAX functionality you can create such a dropdown.

In this article, we introduce a set of CSS naming conventions that we have applied in several big projects and achieved success. The goal of these naming conventions is to eliminate the possibility of naming conflicts, facilitate debugging and maintenance, and to simplify the naming process.

I have had to do this a couple of times now so I figured I would share it with the community. I am going to keep this short because I really hope that you are familiar with jQueryUI's Sortable class before starting this tutorial.
