title: Magento child html -- get parent caller
body: <p>I am in the template file <code>price.phtml</code>.  I would like to have some line of code that looks at the parent that is calling the block and do some behavior based on that.  Essentially if the parent is a catalog list page, I want a <code>from:</code>  tag to be added to the price.  If the parent is <code>configurable.phtml</code>, I want to simply display the price as normal.</p>
  
  <p>I already have the code to add the <code>from:</code> to the price but I need the if statement to tell what the parent caller is.</p>
  
  <p>I have seen something like <code>::parent</code> before when perusing Mage files, but I don't know if that is applicable here...</p>
  
  <p>Thanks!</p>
