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.
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.
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.
CGridView (or CListView) together with CActiveDataProvider is a very powerful combination of the built-in tools of Yii. But how do they work together to accomplish their fantastic functions? And what are you expected to do to use them and to customize their behaviors? This article explains the very basics of them.
This little tutorial explains a way how you can retrieve more parameters from Yii::app()->user by adding a component that extends CWebUser and retrieves the user information from database table named User.
You have a multilingual application, and you want the URL of a page to be different for different languages, to account for SEO. The URL for the contact page for example should look like http://something.com/en/contact in english, and http://something.com/de/contact in german. This tutorial describes how to make it happen.
Note that currently selected language is always a part of the URL, and thus available to the application through $_GET. You don't have to use sessions variables to keep track of the language if you don't want to.
