First param in CActiveDataProvider could be a string with model name or instance of class. So, you may use CActiveRecord::cache() for cache, but you need set third param to 2, because you should cache 2 queries: counting and get data.

Using filters on CGridView with CActiveDataProvider is easy, but with CArrayDataProvider it is a bit tricky.

The only thing required is simple, we just need to create a view that will be partially rendered by a call to a controller (using renderPartial) and make sure that we process output -setting to true the parameter on the function. Everything will work as expected but...

CFormatter is one of Yii's core components and used to format values displayed in widgets like CGridView or CDetailView. All classic formats like numbers, text, urls or datetime are supported but you may have to use a formatting rule that isn't built in. Let's say we want to display arrays of strings (like tags associated with a product model)...

This is what I did. Its the EASIEST solution that I know of. I just reused the advanced search done in CGridView.

in Yii versions previous to 1.1.9 exceptions was handled differently during ajax request and displayed by CApplication::displayException(). This way the exception message displayed on ajax requests could not be customized.
The message for the CGridView delete request with YII_DEBUG set to true l...

Virtually all Yii applications are built on top of a database, and though Yii is very flexible in how it addresses your DB, some design choices make things more convenient than others.

Whatever reason, it turns out to be easy enough to add that feature to your application. :)

in model add the following code:

If in your application you have to proceed to a complex SQL query that is not associated to a model, you will use CDbDataReader like it is described in the Yii documentation. An example could be

上一篇 关于 Yii CHttpSession性能优化篇之源码流程分析 有详细分析CHttpSession执行流程，在了解CHttpSession的详细执行流程之后，我们就可以非常轻松的扩展Yii Session，来优化和符合自己的业务流程。

当我们使用Yii数据库去保存Session时，只要简单的配置就可以完成这个功能，在进行性能优化这个主题之前，我们先来查看一下CHttpSession和CDBHttpSession源代码，探讨CHttpSession和CDBHttpSession的流程再进行深一步优化主题。

这篇文章将介绍使用Linux cronjobs去自动化执行Yii Console Application(控制台)任务，像每天晚上执行缓存清理，临时文件清理，发送邮件，网站备份等等，重复的工作都交给服务器后台去完成，Yii本身已经提供了强大的支持，我们所做的工作就很少,当使用yiic webapp 自动生成工程结构时，强大的Yii已经全部帮我们生成好，仅仅只需三步。

How many of us wonder how we can upgrade the website without hurting the operation of our WebApp?

Many time for SEO porpouses is important that each page will have a unique address.

With Yii you can use one CActiveForm for collecting data for two or more models with ajax validation and client validation.

I was looking around wiki and found that was no approach as the one I did so I guessed this is worth to write.

This tutorial will show you how to create Ajax dialog which allows to create new model, update or delete existing model. It works with simple links, CGridView button column links, adds a minimal amount of code and degrades gracefully with JavaScript turned off.

This article will show you how to add links and class to each node in ctreeview. so you can attach events in js by obtaining handler on anchor or class.

Maybe it looks simple, but some time ago I need some time to find a solution of this case. I finally got it, and I want to share that I also experienced such cases. So that it can make reference.
