How magento create encrypted password

Magento create encrypted password with,


Here is the logic of decrypt($password) function,

 $password = "12345678";
 $salt = "at";
 $encyPasswod = md5($salt.$pass).":".$salt;

In above function, $salt is randomly generated string of two alphanumeric character.

How magento validate password

Bellow functiona will validate the user password,

Mage::getModel('customer/customer')->authenticate($email, $password);

Logic behind above function is,

 $email = "";
 $password = "123456";

 //Load a customer by email address
 $customer = Mage::getModel('customer/customer')

 // if loaded! get stored password from database
 $hash = $customer->getData("password_hash");

 // Get last two digits separate by :";
 $hashArr = explode(':', $hash);

 public function validateHash($password, $hash)
     $hashArr = explode(':', $hash);
     switch (count($hashArr)) {
         case 1:
             return $this->hash($password) === $hash;
         case 2:
             return $this->hash($hashArr[1] . $password) === $hashArr[0];
     Mage::throwException('Invalid hash.');

Magento – Show Product Reviews on Product detail Page

Product review is one of the good feature of magento but with default magento theme product review listed on separate page. Usually  customer like to see all detail on same page instead redirect to another page. With this though we would like to show the product reviews  on product detail page only.

Bellow are steps which can help you to show product reviews on product detail page.

Call product review block on product detail page, you can add bellow code to local.xml

    <reference name="content">
        <block type="review/product_view_list" name="" as="reviews" template="review/product/view/review_summary.phtml" />
    </reference name="content">

Create new template file review_summary.phtml, under template/review/product/view/ folder

    $_items = $this->getReviewsCollection()->getItems();
    if( count( $_items ) )
        foreach( $_items as $_review ){
        // Get the Review Title
        echo $this->htmlEscape( $_review->getTitle() );
        // Get the Review Content
        echo $this->htmlEscape( $_review->getDetail() );
        // Get the Review Author
        echo $this->htmlEscape( $_review->getNickname() );

Call review block on view.phtml, where you need the block to be show based on your design.

<?php echo $this->getChildHtml('reviews') ?>
