With yii you're able to create ajax requests and updates easily. But most times you always want to show a loading indicatior to your user.

After adding proper form to the main layout, like:

Yii's ActiveRecord classes are powerful, but they fall short when you want to have a configurable table prefix for your application.

While yiic shell tool is very convenient at generating skeleton code in our application, the generated code is not always what we want.

Adding HTTP compression to your application could never have been easier!

This tutorial will show you how to use the Pogostick Yii Extension Library to make an HTML TEXTAREA input element into a full-fledged WYSIWYG editor pretty much with very little code.

Logging context information (session, user, ...) to the logfile can be of great help tracking down problems with specific users.

Large applications are often divided into front-end and back-end (or even more ends) depending on the target user groups. The front-end should be used by common users, while the back-end mainly the administrators or staff members. The two ends usually have dramatically different appearance, even though they may share a lot of code underneath. In this tutorial, we describe a way of organizing direc...

Application configuration determines how an Yii application should behave, because it is the only parameter passed in the entry script. An application, on the other hand, needs to behave differently under different circumstances. For example, an application may need different configurations when running in production mode, development mode and testing mode; In a team development environment, each...

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...

Since Yii 1.0.5 you can use named scopes with ActiveRecords. They are a great help in simplifying your query calls.

This is the first real problem that I encountered using Yii, trying to make a Model input repeatable in the form, validate and save them.
