3. 1. Why I choose Yii Framework?
- Demand:
To build a robust and solid CMS. (Easy for both Dev., End-Users)
Previous Frameworks I worked with:
+ Zend Framework.
+ CakePHP.
+ MVC Framework made by myself.
Previous CMS I worked with:

Yii.
Advantages:
- Yii performance - Optimize with APC cache and Lazy Loading -
http://www.yiiframework.com/performance/
- Very good and clear documents.
- Rich of modules and extensions.
Disadvantages:
- Forum discussions is not really active.

7. Yii Rich Features
MVC Design Pattern and Request Handle Workflow
- http://www.yiiframework.com/doc/guide/1.1/en/basics.mvc
8. Yii Rich Features
New Application Generator - Demo
- Run php yii/framework/yiic.php webapp /location
- Run and Test new application
10. Yii Rich Features
URLManager configuration
- Do not over-use URLManager due to downgrade of performance.
(Using .htaccess as much as possible)
11. Yii Rich Features
Support multi-database systems (MySQL, SQLlite,...)
- Yii database is built on top of PDO. You can switch betweeb DBMS (MySQL,
SQL,...) without the need to change application code
- Database configuration in protected/config/main.php
12. Yii Rich Features
Gii Generator: Model, Controller, CRUD,...Your Own generator
Demo:
- Config database connection first.
- Create new User Table in Database.
CREATE TABLE `yiisample`.`user` (
`id` INT( 11 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`name` VARCHAR( 255 ) NOT NULL ,
`email` VARCHAR( 255 ) NOT NULL ,
`status` TINYINT( 2 ) NOT NULL DEFAULT '0'
) ENGINE = INNODB;
- Enable Gii in Applicaion
- Using Gii to generate code.
13. Yii Rich Features
Controllers, Filters, AccessControl and Views
Demo:
- Learn the basic workflow of controllers and views.
- Learn using filters with AccessControl.
- Learn more about the views:

14. Yii Rich Features
Models (CActiveRecord, DAO...)
Demo CActiveRecord:
+ http://www.yiiframework.com/doc/guide/1.1/en/database.ar
- Using CActiveRecord to manage Table in Database.
- Features of CActiveRecord:
+ Rules and Validators
+ Behaviors and Events
+ Integreate data to Widgets, CActiveForm,...
Demo DAO:
+ http://www.yiiframework.com/doc/guide/1.1/en/database.dao
15. Yii Rich Features
Models - CActiveRecord vs DAO
CActiveRecord:
- Good for Inputting (rules, validators,...).
- Quick deploy thanks to Gii Generator.
- Easy to handle.
DAO:
- Less memory.
- Good for retrieving data.
Advice:
Caching and choose DAO to deploy application fast first. Implement by DAO
later.
http://www.yiiframework.com/forum/index.php/topic/25825-dao-vs-activerecord-
methods/
http://www.sheldmandu.com/php/php-mvc-frameworks/yii-dao-vs-active-record-
performance
16. Yii Rich Features
Forms - CActiveForm
- It is based on Model Concept to collect user data.
- It support rules and validators like Model.
- Demo ContactForm with rules and validators
17. Yii Rich Features
Flexible Object-Oriented Programming (OOP)
- In Yii, you can extend any core class you want. Keep core code clean and
logical.
- Demo with User Components.
To manage Users, Yii use 2 components/classes:
+ CWebUser : a component in application variable. It stores basic user
information of current request (username, email, login by cookie).
+ CUserIdentity : a class to help user "Log in" to system. (Allow users to login
by using File Data, Pre-Defined data or Database data,...)
18. Yii Rich Features

CWebUser
User Login Workflow
Login by Login Form
CUserIdentity will
Login By check login information If identity is ok and no error, the
Form from user user will be truly logged in to
User types his system by creating session for
username and You can implement that user.
password core class here
Login by Cookie
If the cookie user send in request
is ok (with some secure check).

19. Yii Rich Features
Session and Cookie Management
- Yii supports Session and Cookie wrapper class.
Session:
- You can use Session Handler by File, Database or Memcache.
'session' => array(
'class' => 'CDbHttpSession',
'connectionID' => 'db',
'autoCreateSessionTable'=>false,
'sessionTableName'=>'gxc_session',
'sessionName'=>'gxc_session_id' //Should Change for Different //Apps
),
You can implement/extend CDbHttpSession for your own use.

),

- Using Asset Managers in Module to publish Asset Files. (Which we can't
directly access due to .htaccess restrict)
- Demo with Rights module.
23. Yii Rich Features

26. Yii Rich Features
Extending Yii - Extensions
Thanks to flexible Yii structure, you can easily extend Yii to:
+ Override core components.
+ Create Behaviors
+ Create Widgets
+ Create Module
