Membuat User Login di YII dengan level

Bagaimana cara membuat user login menggunakan database? Begini caranya:

1. Buat tabel user

CREATE TABLE IF NOT EXISTS `user` (
 `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
 `username` varchar(100) NOT NULL,
 `password` varchar(200) NOT NULL,
 `level` tinyint(1) NOT NULL DEFAULT '0',
 PRIMARY KEY (`id`),
 UNIQUE KEY `username_UNIQUE` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. Buat model dan CRUD untuk tabel user menggunakan Yii.

3. Buka file _form.php pada /protected/views/user/_form.php. Hapus field untuk password, dan tambahkan field untuk password, password_repeat.

<div class="row">
 <?php echo $form->labelEx($model,'username'); ?>
 <?php echo $form->textField($model,'username',array('size'=>20,'maxlength'=>64)); ?>
 <?php echo $form->error($model,'username'); ?>
 </div>
<div class="row">
 <?php echo $form->labelEx($model,'password'); ?>
 <?php echo $form->passwordField($model,'password',array('size'=>20,'maxlength'=>64)); ?>
 <?php echo $form->error($model,'password'); ?>
 </div>
<div class="row">
 <?php echo $form->labelEx($model,'password_repeat'); ?>
 <?php echo $form->passwordField($model,'password_repeat',array('size'=>20,'maxlength'=>64)); ?>
 <?php echo $form->error($model,'password_repeat'); ?>
 </div>
<div class="row">
 <?php echo $form->labelEx($model,'level'); ?>
 <?php echo $form->dropDownList($model,'level', Yii::app()->user->getUserLevelsList(), array('empty'=>'-- Pilih Level --')); ?> //getUserLevelsList() berada di /protected/components/EWebUser.php
 <?php echo $form->error($model,'level'); ?>
 </div>

4. Buka file User.php pada /protected/models/User.php.

tambah variabel untuk password dan password_repeat

class User extends CActiveRecord
{
 public $password;
 public $password_repeat;



rules()

public function rules()
{
 // NOTE: you should only define rules for those attributes that
 // will receive user inputs.
 return array(
 array('username', 'required'),
 array('username', 'unique'),
 array('username', 'length', 'min'=>3, 'max'=>40),
 array('password, password_repeat', 'required', 'on' => 'passwordset'),
 array('password', 'length', 'min'=>8, 'max'=>40, 'on' => 'passwordset'),
 array('password', 'compare', 'compareAttribute' => 'password_repeat'),
 array('username, password, password_repeat', 'safe'),
 array('level', 'numerical', 'integerOnly'=>true),
 // The following rule is used by search().
 // @todo Please remove those attributes that should not be searched.
 array('username, level', 'safe', 'on'=>'search'),
 );
}


attributeLabels()

public function attributeLabels()
{
 return array(
   'id' => 'ID',
   'username' => 'Username',
   'password' => 'Password',
   'password_repeat' => 'Password Repeat',
   'level' => 'Level',
 );
}

5. Buka file UserIdentity.php di /protected/components/UserIdentity.php.

<?php
class UserIdentity extends CUserIdentity
{
 private $_id;
 private $level;

 /**
 * Authenticates a user.
 * @return boolean whether authentication succeeds.
 */
 public function authenticate()
 {
 $username = strtolower($this->username);
 $user = User::model()->find('LOWER(username)=?', array($username));

 if($user===null)
   $this->errorCode=self::ERROR_USERNAME_INVALID;

 else if(!$user->check($this->password))
   $this->errorCode = self::ERROR_PASSWORD_INVALID;

 else{
   // successful login
   $this->_id = $user->id;
   $this->username = $user->username;
   $this->setState('level', $user->level); //untuk memanggil level di database menggunakan EWebUser.php nanti
   $this->errorCode = self::ERROR_NONE;
 }
 return $this->errorCode == self::ERROR_NONE;
 }

 public function getId()
 {
   return $this->_id;
 }
}

6. Buka file EWebUser.php di /protected/components/EWebUser.php.

<?php
class EWebUser extends CWebUser
{
 private $_userTable = array
 (
   0=>'Member',
   1=>'Moderator',
   8=>'Admin',
   9=>'Owner'
 );

 protected $_model;

function isAdmin()
 {
 //Access this via Yii::app()->user->isAdmin()

   return (Yii::app()->user->isGuest) ? FALSE : $this->level == 8;
 }

 public function isSuperadmin()
 {
 //Access this via Yii::app()->user->isSuperadmin()
   return (Yii::app()->user->isGuest) ? FALSE : $this->level == 9;
 }

 public function canAccess($minimumLevel)
 {
 //Access this via Yii::app()->user->canAccess(9)
   return (Yii::app()->user->isGuest) ? FALSE : $this->level >= $minimumLevel;
 }

 public function getRoleName()
 {
 //Access this via Yii::app()->user->roleName()
   return (Yii::app()->user->isGuest) ? '' : $this->getUserLabel($this->level);
 }

 public function getUserLabel($level)
 {
 //Use this for example as a column in CGridView.columns:
 //
 //array('value'=>'Yii::app()->user->getUserLabel($data->level)'),
   return $this->_userTable[$level];
 }

 public function getUserLevelsList()
 {
 //Access this via Yii::app()->user->getUserLevelsList()
   return $this->_userTable;
 }
}
?>

7. Buka file main.php di /protected/config/main.php. Tambahkan class untuk EWebUser di components.

// application components
'components'=>array(
   'user'=>array(
   // enable cookie-based authentication
   'allowAutoLogin'=>true,
   'class'=>'application.components.EWebUser',
 ),

8. Buka file User.php lagi, untuk membuat hash.

hash()

/**
 * Using the crypt library that comes with PHP and providing no salt value,
 * so that it is randomly generated by the library.
 */
 public function hash($value)
 {
   return crypt($value);
 }


beforeSave()

/**
 * We need to call the encryption function whenever we store a password,
 * – on create and on update –
 * so we will overload the beforeSave function to do the hashing.
 */
protected function beforeSave()
{
 if (parent::beforeSave()) {
   if (!empty($this->password))
     $this->password = $this->hash($this->password);

   /* contoh kalau ada tgl_masuk dan tgl keluar
   if ($this->isNewRecord)
     $this->tgl_masuk = new CDbExpression('NOW()');

   $this->tgl_update = new CDbExpression('NOW()');
   */

   return true;
 }
 return false;
}

9. Buka file UserController.php di /protected/controllers/UserController.php.

actionCreate()

public function actionCreate()
 {
   $model=new User('passwordset'); //scenario passwordset digunakan pada rules() di model User.php seperti 'on'=>'passwordset'
   // Uncomment the following line if AJAX validation is needed
   // $this->performAjaxValidation($model);
   if(isset($_POST['User']))
   {
     $model->attributes=$_POST['User'];
     if($model->save())
        $this->redirect(array('view','id'=>$model->id));
   }
   $this->render('create',array(
     'model'=>$model,
   ));
 }



actionUpdate()

public function actionUpdate($id)
{
   $model=$this->loadModel($id);
  // Uncomment the following line if AJAX validation is needed
  // $this->performAjaxValidation($model);
  if(isset($_POST['User']))
   {
     $model->attributes=$_POST['User'];

     // We only want to apply the scenario when a password field has been entered,
     // so set the scenario on the model conditionally.
     if ($model->password || $model->password_repeat)
       $model->scenario = 'passwordset';

     if($model->save())
       $this->redirect(array('view','id'=>$model->id));
   }
  $this->render('update',array(
   'model'=>$model,
  ));
}
10. Buka User.php dan tambahkan fungsi check agar pada saat login akan dicek hashnya.

/**
 * For logging in, function to check a password value against the hashed value.
 */
public function check($value)
{
 $new_hash = crypt($value, $this->password);

 if ($new_hash == $this->password) {
   return true;
 }
 return false;
}

Membuat Login di Yii Framework

Telah berhari-hari saya memahami framework yii, tiba akhirnya sedikit-sedikit memahami dasar dari yii framework. Saat ini saya mencoba membuat login dengan yii, kuncinya anda harus memahami terebih dahulu mengenai GII yang dasarannya yaitu CRUD. Jika sudah silahkan ikuti langkah-langkah berikut :

1. Buat Database user
2. Gantii userIdentity
3. update model
4. update Controller

Buat database

silakan copy paste sql ini ke dalam database anda.
