"By Example" cookbook pages will provide coding examples for many of the commonly used classes within Yii. We will try to provide as many usage examples as possible for keep these pages as helpful as possible.

First declare an attribute to store the file name in the model class (either a form model or an active record model). Also declare a file validation rule for this attribute to ensure a file is uploaded with specific extension name.

Hi. This is first article with my Yii v1 tutorial. I had to split it into 2 articles as there's limited length of texts on Wiki. So once you understand basics, you can read the 2nd article here: Yii for beginners 2.

Often you'll need a form with two dropdowns, and one dropdown's values will be dependent on the value of the other dropdown. Using Yii's built-in AJAX functionality you can create such a dropdown.

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.");

The easiest way to update content in AJAX is to use the renderPartial method.

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:

Lets say we have two models and relation between them:

This page is created to supply short directions and general tips for managing a Yii application in NetBeans IDE.

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...

Many newcomers to Yii ask about the assets/ directory found under the webroot, and this article means to explain why it's there and how to work with it.

When you define or extend a class, you can create class variables and methods in Yii just like you can in any other PHP system:

class Comment extends CActiveRecord {
    public $helperVariable;
    public function rules() { ... }
    ...
}

and then use them in the obvious way:

$var   = $model->helperVariable;
$rules = $model->rules();

This part everybody understa...

Scenarios are an extremely useful tool for separating validation tasks on any class you use derived from CModel. In this tutorial we will use CActiveRecord.

There are many ways to automate the setting of timestamps in yii ActiveRecord models. Three are presented here:

Update: This wiki has been rewritten to be in line with Yii 1.1.14. Since many of the detailed complexities are now handled by Yii, the article focuses on how the crypt() built-in function works and why it's important to use it correctly.

hi guys, Here I'm going to give you a working example of ajax form submiting in Yii.

In this tutorial we will learn how to realize a create interface using a dialog.

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

These features provide endless possibilities and unbelievable flexibility, but as current documentation does not give more than a few examples, it might be difficult to fully understand their internals and requirements.

This little tutorial explains a way how you can retrieve more parameters from Yii::app()->user by adding a component that extends CWebUser and retrieves the user information from database table named User.
