Wiki articles

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.

Many desktop programmers are used to having dynamic forms, where clicking on a record in a parent sub-form, updates another sub-form with the child records. While having many levels of nested sub-forms in a single view might not be such a good idea for a web application, I thought doing it one level deep might be interesting and useful. But, instead of sub-forms I used CGridViews.

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.

There are a few issues with the other solutions I originally used that I found from other wikis. I address the issues I had in this much simpler and shorter way. I am also going to explain what is going into way more detail than others to help people understand what's going on.

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!
