Authorization And Authentication


Recommended Posts

Hi

I am new to Yii Framework

I am trying to add authentications to my website and trying to take username(email) and password from database instead of demodemo or admin/admin which are default

 

I have completed the coding but when i am trying to manage users table it is displaying a message "Error 403--You are not authorized to perform this action."

 

 

This is my site controller.php

 

<?php

class SiteController extends Controller
{
/**
 * Declares class-based actions.
 */
public function actions()
{
	return array(
		// captcha action renders the CAPTCHA image displayed on the contact page
		'captcha'=>array(
			'class'=>'CCaptchaAction',
			'backColor'=>0xFFFFFF,
		),
		// page action renders "static" pages stored under 'protected/views/site/pages'
		// They can be accessed via: index.php?r=site/page&view=FileName
		'page'=>array(
			'class'=>'CViewAction',
		),
	);
}

/**
 * This is the default 'index' action that is invoked
 * when an action is not explicitly requested by users.
 */
public function actionIndex()
{
	// renders the view file 'protected/views/site/index.php'
	// using the default layout 'protected/views/layouts/main.php'
	$this->render('index');
}

/**
 * This is the action to handle external exceptions.
 */
public function actionError()
{
    if($error=Yii::app()->errorHandler->error)
    {
    	if(Yii::app()->request->isAjaxRequest)
    		echo $error['message'];
    	else
        	$this->render('error', $error);
    }
}

/**
 * Displays the contact page
 */
public function actionContact()
{
	$model=new ContactForm;
	if(isset($_POST['ContactForm']))
	{
		$model->attributes=$_POST['ContactForm'];
		if($model->validate())
		{
			$headers="From: {$model->email}\r\nReply-To: {$model->email}";
			mail(Yii::app()->params['adminEmail'],$model->subject,$model->body,$headers);
			Yii::app()->user->setFlash('contact','Thank you for contacting us. We will respond to you as soon as possible.');
			$this->refresh();
		}
	}
	$this->render('contact',array('model'=>$model));
}

/**
 * Displays the login page
 */
public function actionLogin()
{
	$model=new LoginForm;
	// if it is ajax validation request
	if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')
	{
		echo CActiveForm::validate($model);
		Yii::app()->end();
	}

	// collect user input data
	if(isset($_POST['LoginForm']))
	{

		$model->attributes=$_POST['LoginForm'];


		// validate user input and redirect to the previous page if valid
		if($model->login())
		{
			//echo "userlogins";
			//print_r($_SESSION);
			//die;
			//$this->redirect(Yii::app()->user->returnUrl);

			$this->redirect('index.php?r=userrolestbl/create');
			//$this->render('userrolestbl/create',array('model'=>$model));
			//echo"success";die;
		}
	}
	// display the login form
	$this->render('login',array('model'=>$model));
}

 */
public function actionLogout()
