Troubleshooting Data with Magento:

How to backup from bundles and get general product info:

Gets the Product ID of the selection

$_selectionID = $_selection->getProductId();

Loads the product model

$_newProduct = Mage::getModel('catalog/product')->load($_selectionID);

Now you can run either a foreach on $_newProduct using:

foreach(($_newProduct->getData())) 

or use var_dump( $_newProduct->getData() )

Or you can dial in on the method you want:

$_newProduct->getTierPrice etc

You can do the same for the selection or option itself by using:

$_selection OR $this->getSelection()

$_selection->getData(); etc…..

Determining Block Name in template:

<?php die(get_class($this)); ?>

Get Store Base URL

Mage::getBaseUrl()

Get Product Attribute By Name

$this->getProductAttribute('product_attribute')

Get Store Currency Code/Symbol

Mage::app()->getStore()-> getCurrentCurrencyCode();
Mage::app()->getLocale()->currency(Mage::app()->getStore()->getCurrentCurrencyCode())->getSymbol();

Troubleshooting New Install:

Htaccess
File Permissions (especially on root folder, 755 for directories, 644 for files)
Check var/report for basic error reporting
Check that database info in app/etc/local.xml is correct
