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.

In this tutorial, we describe how to implement multiple layouts for action views in an application. As an example, we assume that the pages in our application will use three different layouts:

The Yii documentation states:

As seen in this post, Yii doesn't enforce how language is set and maintained within the session.

Have you ever wanted to use an auto-complete field to look up a user or some other data, but want the database ID of that user or data returned as well so that you can more easily perform some function when the form is submitted? Thanks to Yii's CAutoComplete widget and [jQuery's Autocomplete plugin](http://plugins.jquery.com/project/jq-autocomp...

Here's a simple way to create a breadcrumb widget to be used in your templates. The idea is just to isolate how the breadcrumb is generated based on an array of crumbs.

In a Web application, we often need to display pages like "about this site", "legal information", whose content are mostly static. There are several approaches to deal with this kind of pages.

Set your messages in a controller:

Yii::app()->user->setFlash('success', "Data1 saved!");
Yii::app()->user->setFlash('error', "Data2 failed!");
Yii::app()->user->setFlash('notice', "Data3 ignored.");

Web feed is a data format used for providing users with frequently updated content. In this article, we describe how to use Zend_Feed, an excellent component from Zend Framework to generate Web feed for an Yii application. This article can also serve as a general guide...

Assume we want to use a single HTML form to collect input for both model A and model B, and we want to display input errors (if any) in the same error summary box. We can define the following action code:

Yii core messages refer to static text strings in the core Yii framework code which are meant to be displayed to end-users (e.g. core exception messages, default validation error messages). Customization of these core messages is needed in two circumstances:

According to the manual http://jp.php.net/manual/en/memcache.installation.php;

To fix issues with display of special language characters once and for all there's a solution: use Unicode UTF-8 everywhere. If everything is set up to use Unicode, you can use mostly every language in your application.
