How to override the Configurable product price with its Simple product price

In Magento , we often face the problem with the configurable product.If you are placing price to the simple product , whatever it might be only the configurable product price will be displayed.

For example , If you want to sell a simple product X which have the price $10 and a simple product Y which have the price of $20

The first step is to create a configurable product with the price $10, after that we need to open the Associative Product tab. Assign the products which we want to use with this configurable product. After assigning the simple products, we can able to see the Super product attributes configuration with the text box for entering the options and price differences .

We need to leave the product X empty and we need to assign (+$10) for the product Y.

In order to overcome this problem and to display the individual simple product prices our simple product. We need to do little modifications in the core code.

Goto  app/code/core/Mage/Catalog/Model/Product/Type/Configurable/Price.php(better override in your local folder)

Search for the method getFinalPrice() and change that to 

public function getFinalPrice($qty=null, $product){//Start edit$selectedAttributes = array();if ($product->getCustomOption('attributes')) {$selectedAttributes = unserialize($product->getCustomOption('attributes')->getValue());}//End editif (sizeof($selectedAttributes)) return $this->getSimpleProductPrice($qty, $product);if (is_null($qty) && !is_null($product->getCalculatedFinalPrice())) {return $product->getCalculatedFinalPrice();}$basePrice = $this->getBasePrice($product, $qty);$finalPrice = $basePrice;$product->setFinalPrice($finalPrice);Mage::dispatchEvent('catalog_product_get_final_price', array('product' => $product, 'qty' => $qty));$finalPrice = $product->getData('final_price');$finalPrice += $this->getTotalConfigurableItemsPrice($product, $finalPrice);$finalPrice += $this->_applyOptionsPrice($product, $qty, $basePrice) - $basePrice;$finalPrice = max(0, $finalPrice);$product->setFinalPrice($finalPrice);return $finalPrice;}Also  add the below method, after getFinalPrice() methodpublic function getSimpleProductPrice($qty=null, $product){$cfgId = $product->getId();$product->getTypeInstance(true)->setStoreFilter($product->getStore(), $product);$attributes = $product->getTypeInstance(true)->getConfigurableAttributes($product);$selectedAttributes = array();if ($product->getCustomOption('attributes')) {$selectedAttributes = unserialize($product->getCustomOption('attributes')->getValue());}$db = Mage::getSingleton('core/resource')->getConnection('core_read');$dbMeta = Mage::getSingleton('core/resource');$sql = <<<SQLSELECT main_table.entity_id FROM {$dbMeta->getTableName('catalog/product')} `main_table` INNER JOIN{$dbMeta->getTableName('catalog/product_super_link')} `sl` ON sl.parent_id = {$cfgId}SQL;foreach($selectedAttributes as $attributeId => $optionId) {$alias = "a{$attributeId}";$sql .= ' INNER JOIN ' . $dbMeta->getTableName('catalog/product') . "_int" . " $alias ON $alias.entity_id = main_table.entity_id AND $alias.attribute_id = $attributeId AND $alias.value = $optionId AND $alias.entity_id = sl.product_id";}$id = $db->fetchOne($sql);return Mage::getModel("catalog/product")->load($id)->getFinalPrice($qty);}

Use of Magento Registry Variable

The Main Advantage of using Magento is because of its registry methods. Registry is a term which is the method of registering or creating a new variable which you can use it later on the functionalities or methods you want to make use of those variables. You can able to use that variable anywhere to get the stored values back.

There are three registry methods available in magento which are listed below

1.  Mage::register

You can register a variable using this register method

Syntax:

Mage::register(‘keyvalue’, $variablename);

Example

For example, I am going to load the product using product id and get all the product details and I register that product details in a variable which I can use it later on to my code

$product_id = ‘23’;$_product = Mage::getModel(‘catalog/product’)->load($product_id);Mage::register(‘product’, $_product);

2.  Mage::registry

This Registery method is used for fetching the registered variable

Syntax:

$newvariable = Mage::registry(‘keyvalue’);

Example

In previous method, we register a product details. In this method we can fetch the registered value.

$productdetails = Mage::registry(‘product’);//This keyalue should be same as that of the variable which we used to register.

3.  Mage::unregister

This Method is used to unregister the variable which is registered

Syntax:

Mage::unregister(‘keyvalue’);

Example:

After fetching all the product details, if we want to remove the values from the stored registry we can use this method.

Mage::unregister(‘product’);
