magento existing method rewrite with module

Question

I have few core files modifications in my app/code/local/Mage folder, but I wan't to make them work as magento module.

My example: I did few small modifications in method getValueHtml in file Mage/Bundle/Block/Sales/Order/Items/Renderer.php and now I wan't this rewritten method to be used.

I have followed online tutorials for blocks rewrite but it is not working for me. I'm missing something, but I can't figure it out. These are my module files:

app/code/local/MyCompany/Bundleproducts/etc/config.xml:

<?xml version="1.0"?>
<config>
 <modules>
 <MyCompany_Bundleproducts>
 <version>1.0.0</version>
 </MyCompany_Bundleproducts>
 </modules>
 <global>
 <blocks>
 <bundle>
 <rewrite>
 <sales_order>MyCompany_Bundleproducts_Block_Sales_Order_Items_Renderer</sales_order>
 </rewrite>
 </bundle>
 </blocks>
 </global>
</config>

app/code/local/MyCompany/Bundleproducts/Block/Sales/Order/Items/Renderer.php:

<?php
class MyCompany_Bundleproducts_Block_Sales_Order_Items_Renderer extends Mage_Bundle_Block_Sales_Order_Items_Renderer
{
 public function getValueHtml($item)
 {
 if ($attributes = $this->getSelectionAttributes($item)) {
 return sprintf('%d', $attributes['qty']) . ' TEST ' .
 $this->escapeHtml($item->getName());
 } else {
 return $this->escapeHtml($item->getName());
 }
 }
}

and app/etc/modules/MyCompany_Bundleproducts.xml

<?xml version="1.0"?>
<config>
 <modules>
 <MyCompany_Bundleproducts>
 <active>true</active>
 <codePool>local</codePool>
 </MyCompany_Bundleproducts>
 </modules>
</config>

Can someone point me to the right direction? Thanks!

Answer 1

your block rewrite should be like this

<blocks>
 <bundle>
 <rewrite>
 <sales_order_items_renderer>MyCompany_Bundleproducts_Block_Sales_Order_Items_Renderer</sales_order_items_renderer>
 </rewrite>
 </bundle>
 </blocks>

Answer 2

You need to include the complete path to the core block while overriding. This is the config.xml code

<?xml version="1.0"?>
<config>
 <modules>
 <MyCompany_Bundleproducts>
 <version>1.0.0</version>
 </MyCompany_Bundleproducts>
 </modules>
 <global>
 <blocks>
 <bundle>
 <rewrite>
 <sales_order_items_renderer>MyCompany_Bundleproducts_Block_Sales_Order_Items_Renderer</sales_order_items_renderer>
 </rewrite>
 </bundle>
 </blocks>
 </global>
</config>
