    <meta name="facebook-domain-verification" content="fhwgzxpzzzeswlj3pfdp7zk7p8xxao" />

Adding Facebook Pixel to WooCommerce stores and WordPress websites

Adding Meta Pixel (or Facebook Pixel – the same thing) to WordPress and Woo is fairly easy process.

function rocksolid_meta_pixel() { ?>
	<!-- Meta Pixel Code -->
	<script>
	  !function(f,b,e,v,n,t,s)
	  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
	  n.callMethod.apply(n,arguments):n.queue.push(arguments)};
	  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
	  n.queue=[];t=b.createElement(e);t.async=!0;
	  t.src=v;s=b.getElementsByTagName(e)[0];
	  s.parentNode.insertBefore(t,s)}(window, document,'script',
	  'https://connect.facebook.net/en_US/fbevents.js');
	  fbq('init', '6312661182131');
	  fbq('track', 'PageView');
	</script>
	<noscript><img height="1" width="1" style="display:none"
	  src="https://www.facebook.com/tr?id=6312661182131&ev=PageView&noscript=1"
	/></noscript>
	<!-- End Meta Pixel Code -->
<?php
}
add_action('wp_head', 'rocksolid_meta_pixel');

Don’t forget to replace example Pixel code with your own Meta Pixel Code (everything between <script> tags).

   if (is_front_page()) { ?>
    <meta name="facebook-domain-verification" content="fhwgzxpzzzeswlj3pfdp7zk7p8xxao" /> 
  <?php } ?>
	<!-- Meta Pixel Code -->
	<script>
	  !function(f,b,e,v,n,t,s)
	  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
	  n.callMethod.apply(n,arguments):n.queue.push(arguments)};
	  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
	  n.queue=[];t=b.createElement(e);t.async=!0;
	  t.src=v;s=b.getElementsByTagName(e)[0];
	  s.parentNode.insertBefore(t,s)}(window, document,'script',
	  'https://connect.facebook.net/en_US/fbevents.js');
	  fbq('init', '6312661182131');
	  fbq('track', 'PageView');
	</script>
	<noscript><img height="1" width="1" style="display:none"
	  src="https://www.facebook.com/tr?id=6312661182131&ev=PageView&noscript=1"
	/></noscript>
	<!-- End Meta Pixel Code -->
<?php
}
add_action('wp_head', 'rocksolid_meta');
