Magento:: Social sharing buttons

• Open app/design/frontend/YOUR_PACKAGE/YOUR_THEME/template/catalog/product/view.phtml
• Find the place where you want to add your links/buttons and add the following:

<?php $productName = $_helper->productAttribute($_product, $_product->getName(), 'name'); ?>
<?php $productUrl = $_helper->productAttribute($_product, $_product->getProductUrl(), 'product_url'); ?>
<?php $productImage = $_product->getImageUrl() ?>

• Add the following code below the variables we defined in the previous step:

// Google Plus
<a href="javascript:popWin('https://plus.google.com/share?url=<?php echo urlencode($productUrl); ?>', 'google', 'width=640,height=480,left=0,top=0,location=no,status=yes,scrollbars=yes,resizable=yes');" title="<?php echo $this->__('Share on Google Plus') ?>">Google Plus</a>
// Facebook
<a href="javascript:popWin('https://www.facebook.com/sharer/sharer.php?u=<?php echo urlencode($productUrl); ?>&t=<?php echo urlencode($productName); ?>', 'facebook', 'width=640,height=480,left=0,top=0,location=no,status=yes,scrollbars=yes,resizable=yes');" title="<?php echo $this->__('Share on Facebook') ?>">Facebook</a>
// Twitter
<a href="javascript:popWin('http://twitter.com/home/?status=<?php echo urlencode($productName . ' (' . $productUrl . ')'); ?>', 'twitter', 'width=640,height=480,left=0,top=0,location=no,status=yes,scrollbars=yes,resizable=yes');" title="<?php echo $this->__('Tweet') ?>">Twitter</a>
// Pinterest
<a href="javascript:popWin('https://pinterest.com/pin/create/button/?url=<?php echo urlencode($productUrl); ?>&media=<?php echo urlencode($productImage); ?>&description=<?php echo urlencode($productName); ?>', 'pinterest', 'width=640,height=480,left=0,top=0,location=no,status=yes,scrollbars=yes,resizable=yes');" title="<?php echo $this->__('Pin it') ?>">Pinterest</a>

Adding OpenGraph meta tags to your Magento store is quite easy. Just add the following code below the last meta tag (should be a meta tag named “robots” if you are using a default Magento head file) in app/design/frontend/YOUR_PACKAGE/YOUR_THEME/template/page/html/head.phtml

<?php $product = Mage::registry('current_product');
if ($product): ?>
<meta property="og:title" content="<?php echo $product->getName(); ?>" />
<meta property="og:type" content="product" />
<meta property="og:url" content="<?php echo $this->helper('catalog/product')->getProductUrl($product); ?>" />
<meta property="og:image" content="<?php echo $this->helper('catalog/image')->init($product, 'image')->resize(300, 300); ?>" />
<meta property="og:description" content="<?php echo strip_tags($product->getShortDescription()); ?>" />
<meta property="og:site_name" content="<?php echo Mage::app()->getStore()->getName() ?>" />
<?php endif; ?>
