Your application is international and you have to select the best language for the user. Your user may have selected 'fr_CA' and you have 'fr_FR' or 'fr' available. What do you do? Here is a tip.

Sometimes we need to create our custom exception and show it to the end user through a friendly way . In this article, I'm showing how to do it using CJuidialog.

The number of languages supported by the standard CJuiDatePicker implementation is limited and the language code to use is different from the application's language code. This Wiki shows how to improve on that.

I am going to show you an effective way to validate the uniqueness of multiple columns.

In this wiki I will show how could wo pass the third parameter to UserIdentity on login authenticate. So we can do separate login authentcation from two or more different models from single login form.

There are cases that model validators should be depended by controller/action and you couldn't manipulate on the model class or using scenarios in easy way

It is difficult to perform user dependent theming through a general configuration in 'main.php'. This article proposes a method to do so through a Factory that dynamically generates classes to allow delayed resolution of actual user values. This means that you can refer to values that are stored in the database through the CActiveRecord before Yii is actually loaded. The values will be fetched...

I wanted to customize the CJuiAutoComplete, so that it displays a thumb image before the label like the one shown in the following image:

This Behaviour helps to view time/date/timestamp/datetime from db to local Date / Time / Date Time format and in local Timezone. And save into db in with db timezone and db format. You only need to include this behaviour in models where need this facility.
