php - How To Add og:price:amount to Magento -

i've managed add other open graph tags our magento head, having no luck displaying price.

the page breaks if add code such as:

meta property="og:price:amount" content="currency($finalprice, true, false); ?>" /

the price needs stripped of currency symbol.

any appreciated.

solution

i managed correct price using following code:

<meta property="og:price:amount" content="<?php echo mage::registry('product')->getfinalprice(); ?>" />

try

  mage::registry('current_product')->getfinalprice(); ?>

instead of

   mage::registry('product')->getfinalprice(); ?>

this current product.
