This tip created in conjunction with IRC #yii channel users emilsedgh and tydeas - thanks!

Many Yii users ask how to create helper classes and functions, and though there are numerous approaches spread out among the forum and wiki articles, this Tutorial tries to bring it all together in one place.

Sometimes we get lost trying to search by a HAS_MANY relation using CActiveRecord or CActiveDataProvider in Yii 1.1. This article is a series of drills that try to describe the practical techniques of searching by a HAS_MANY relation.

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

• iteration_count_log2 controls the number of iterations for key stretching. A setting of 8 means the hash algorithm will be applied 2^⁸ = 256 times. This setting should be kept between 4 and 31.
• portable_hashes controls whether portable hashes should be used or not. Portable hashes are salted MD5 hashes prefixed by $P$.

Hello ppl. Even though i have a small experience with yii I though of writing this to help people which want to do something similar.

If you need simple Role based access control without the long RBAC process then this article is just for you. Lets jump to the point.

By default, the expression Yii::app()->user returns a [CWebUser] [application component](http://www.yiiframework.com/doc/guide/basics.application#application-component) which represents the information that are closely related with the current user. Some information can be persistent throughout the current user session. For example, [CWebUser] already comes with a [name|CWebUser::name] property th...

First of all, You must change component config to enable the default Yii CSRF validation.

Since version 5.4 PHP can work as a simple webserver so you can develop Yii applications without installing Apache. That's how to use it:

class Post extends CActiveRecord {

...

} ` When you list Authors in grid you would like to print the count of posts in column, allow sorting on this column and probably filtering by the count.

Almost all the information you need whilst working with yii is written in the Class Reference.

We often need to display a success page after the user has submitted a form without problem. We may show some welcome message after a user registers a new account. There are many ways to implement this workflow. In this article, I will explain a method that exploits flash messages.

A simple and effective way to keep track what your users are doing within your application is to log their activities related to database modifications. You can log whenever a record was inserted, changed or deleted, and also when and by which user this was done. For a [CActiveRecord] Model you could use a behavior for this purpose. This way you will be able to add log functionality to ActiveRecor...

The customary configuration of a Yii application includes just a single database section in the protected/config/main.php file, but it's easy to extend this to support more than one, tying each Model to one of the databases.

For some applications it can be advantageous for administration reasons to allow site administrators to login as other users. This is sometimes called user impersonation or "becoming that user".

• add under runtime directory, a new one call it search, it will be used for the index files that Zend Lucene will create. Make sure it is writable!

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.

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

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:
