Relational databases do not support inheritance so if we need to represent it, we have to somehow store meta info while keeping performance by minimizing JOINs. One way to solve this problem is using single table inheritance. All fields for the whole class tree are stored in a single table. Class name is stored in the type field...
When to use Active Record is a common question among developers, Yii and overall.
I have had to do this a couple of times now so I figured I would share it with the community. I am going to keep this short because I really hope that you are familiar with jQueryUI's Sortable class before starting this tutorial.
While there is a reasonable amount of documentation regarding CForm (form builder) and file uploads seperately, there really is not any coverage of both in combination.
Sometimes we need some complicated view to be displayed (such as generating complicated table). Most people suggest that in MVC the View must be as simple as possible (don't have too much loops, etc). So what we have to do is to hide away the complex code by putting it at somewhere else. The following are few places options to keep the function:
Since I used CGridView for a first time, I didn't like how it handled operations like sorting, filtering, changing page and etc using AJAX.
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.
The Yii Framework is very powerful and it provides a lot of functionality right from the pre-built webapp. One of the nice things that is already established for you as a developer is the Login authentication. While the default configuration simply sets it up to run against an array of hard coded usernames and passwords, the [Yii Blog Tutorial](http://www.yiiframework.com/doc/blog/1.1/en/prototype...
There are situations in which Active Record will generate nonsense queries from what a nieve Yii user might think is reasonable code. One such situation is a CActiveDataProvider using CDbCriteria to get data from parent and 1:n child table with a condition on the child table.
Let's say our table 'mug' has a column named 'color' of the type ENUM('red','green','blue').
We want to replace the textfield for the attribute color in the create and update forms of a 'mug' with a drop down list, which has the enum values as options.

Assuming that you have already install the wampserver on your windows.
This article tries to explain the steps required in integrating the HybridAuth into Yii directly, without using an extension.
This article intends to summarize the steps taken to set up PHPUnit and Selenium for a Yii project, with IntelliJ IDEA Ultimate (the IDE). It was done on Mac OS X 10.6.
I guess this is a tip on how to execute some code before every action in a controller, because I will tell you how I did it and maybe you can use the idea in your project.
If you use yiic to generate webApplication there will be a layout folder under the protected/views/, and the Controller class under protected/components which will use by default these layouts files.
Please, note. This article is entirely based on a work done by me colleague developer, who hasn't got account on this webpage and also hasn't got time for writing this article. I'm writing it for him. I will try to forward him any comments that may appear, but can't assure if/when he'll be able to answer. I'm far, far less experienced in Oracle therefore I won't probably be able to help myself.
I can see many questions regarding configuring the path using Windows OS. I could hardly get the right information about it. The cook book has defined for Linux. So I would like to share my idea on it. To configure the Yii path using Windows OS,
In case of a multilingual application, one might consider it a reasonable approach to store the preferred language of the user in a session variable, and after that, every time a page is requested, to check this session variable and render the page in the indicated language.
This tutorial shows a Yii-way of doing this.
We implement an event handler for the onBeginRequest event; as the nam...
