<?
    public function encryptIt( $q ) {
        $cryptKey  = 'OrangeOnlineMedia';
        $qEncoded      = base64_encode( mcrypt_encrypt( MCRYPT_RIJNDAEL_256, md5( $cryptKey ), $q, MCRYPT_MODE_CBC, md5( md5( $cryptKey ) ) ) );
        return( $qEncoded );
    }

    public function decryptIt( $q ) {
        $cryptKey  = 'OrangeOnlineMedia';
        $qDecoded      = rtrim( mcrypt_decrypt( MCRYPT_RIJNDAEL_256, md5( $cryptKey ), base64_decode( $q ), MCRYPT_MODE_CBC, md5( md5( $cryptKey ) ) ), "\0");

i include this line in controller page("CustomersController")

top of the page include using this line

$encFile =Yii::getAlias('@common'). '\extensions\encryptdecrypt.php';
require_once($encFile);

and use the function in an action code bellow

public function actionCreate()
{
    $model = new Customers();

    if ($model->load(Yii::$app->request->post()) ) {

        $model->password=encryptIt($model->password);            
        if($model->created_date==null)
        {
          $model->created_date=date('y-m-d') ; 
        }
        $model->save();
        return $this->redirect(['view', 'id' => $model->customer_id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

here i am getting the following error "Call to undefined function backend\\controllers\\encryptIt()"

thanks

Yii2 Uses PSR-4 AutoLoader Rule, so first save Security.php

In common\\extensions folder, then open Security.php and create class in it.

<?php

namespace common\extensions;

class Security {

    public function encrypt(){
    // todo
    }

    public function decrypt(){
    // todo
    }

}

and then in your CustomersController action Create use it like this:

public function actionCreate()
{
    $model = new Customers();

    if ($model->load(Yii::$app->request->post()) ) {
        $security = new \common\extensions\Security(); // <-- Create Object Here
        $model->password= $security->encrypt($model->password);            
        if($model->created_date==null)
        {
          $model->created_date=date('y-m-d') ; 
        }
        $model->save();
        return $this->redirect(['view', 'id' => $model->customer_id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

BTW in Yii2 you can generate secure password hash like this too: Yii::$app->security->generatePasswordHash($password);

Answer 2

try getting

 $encFile = Yii::getAlias('@common/extensions/encryptdecrypt.php'); 

try also

var_dump($encFile) 

and check the pathname

Answer 3

May be you are using wrong folder. As you mentioned file is in common\\extension folder

$encFile =Yii::getAlias('@common'). '\extension\encryptdecrypt.php';
require_once($encFile);

Answer 4

Make use of DOCUMENT_ROOT

The document root directory under which the current script is executing, as defined in the server's configuration file.

Example

To include files regardless of server type, do this:

$_SERVER['DOCUMENT_ROOT'] .Yii::getAlias('@common/sub_directory/yourFileName.php');
// outputs something like: /var/www/YiiApp/common/sub_directory/yourFileName.php

# or 
$_SERVER['DOCUMENT_ROOT'] .Yii::getAlias('@web/images/image.jpg');
// outputs something like: /var/www/YiiApp/web/images/image.jpg
