Yii – An Introduction


Introduction

Yii is a free, open-source Web application

development framework written in PHP5 that

promotes clean, DRY design and encourages rapid

development. It works to streamline your

application development and helps to ensure an

extremely efficient, extensible, and maintainable

end product.

Extract the requirements folder to a web-

accessible directory

http://www.example.com/requirements

Requirements

command from a web-accessible directory

/path/to/php.exe /path/to/framework/yiic.php webapp

myfirstyiiapp


That’s it!

Features


Features

Skinning and theming

You can select theme at project level, controller level, action

level Or based on some condition in action.

Error handling and logging

Errors are handled and presented more nicely, and log

messages can be categorized, filtered and routed to different

destinations.

Features

Automatic code generation

Yii provides a set of spontaneous and highly extensible code

generation tools that can help you quickly generate the code

you need for features such as form input, CRUD.

Unit and functionality testing

Test-Driven Development - using PHPUnit and Selenium

Remote Control

Features

Authentication and authorization

Yii has built-in authentication support. It also supports

authorization via hierarchical role-based access control.

Layered caching scheme

Yii supports data caching, page caching, fragment caching

and dynamic content. The storage medium of caching can

be changed easily without touching the application code.

Code Samples


Model Class class Post extends CActiveRecord

{

/**

* Retrieves a list of models based on the current search/filter conditions.

* @return CActiveDataProvider the data provider that can return the models based

on the search/filter conditions.

*/

public function search()

{

$criteria=new CDbCriteria;

$criteria->compare('content ',$this->content );

$criteria->compare('title ',$this->title ,true);

return new CActiveDataProvider($this, array(

'criteria'=>$criteria,

));

}

}

Controller class PostController extends Controller {

/**

* Displays a particular model.

* @param integer $id the ID of the model to be displayed

*/

public function actionView($id)

{

$post = Post::model()->findByPk($id);

if(!$post)

throw new CHttpException(404);

$this->render('view', array(

'post' => $post,

));

}

}

Using Model From Controller

Create $post = new Post;

$post->title = 'sample post';

$post->content = 'post body

content';

$post->save(); <- This is validated

Select $post=Post::model()->find(array(

'select'=>'title',

'condition'=>'postID=:postID',

'params'=>array(':postID'=>2),

));

Update $post = Post::model()->findByPk(2);

$post->title = ‘New title’;

$post->save(); <- This is validated

View $this->breadcrumbs=array(

'Posts'=>array('index'),

$post>title,

);

?>

<h1>View Post #<?php echo $post>id; ?></h1>

<?php $this->widget('zii.widgets.CDetailView', array(

'data'=>$post,

'attributes'=>array(

'title', 'content',

),

)); ?>

<table> <tr><th>User id</th><td><?php echo $user->id; ?></td></tr> <tr><th>User name</th><td><?php echo $user->username; ?></td></tr> <tr><th>Role</th><td><?php echo $user->user_role_id; ?></td></tr> </table>

If a property of only user model is accessed, only that table will be queried


<table> <tr><th>User id</th><td><?php echo $user->id; ?></td></tr> <tr><th>User name</th><td><?php echo $user->username; ?></td></tr> <tr><th>Role</th><td><?php echo $user->userRole->role_name; ?></td></tr> </table>

If a property of related mode is accessed, only then it will query related model
