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.

30. Code Samples
www.folio3.com@folio_3

31. 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,
));
}
}

32. 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,
));
}
}

33. 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

34. 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',
),
)); ?>

35. Performance
www.folio3.com@folio_3

36. Performance – Comparison with other frameworks
Source: http://www.yiiframework.com/performance

37. Performance – Lazy loading example
Schema
/**
* Create a relation in TblUser Model Class with User Role (tbl_role) table
*/
public function relations()
{
return array(
'userRole' => array(self::BELONGS_TO, 'TblRole', 'user_role_id'),
);
}
TblUserModel

38. Performance – Lazy loading example
<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

39. Performance – Lazy loading example
<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
