Add Dynamic Post Link To Facebook With Post Thumbnail

Question

I'm using this code from the official FB Developer page

<div class="fb-share-button" data-href="https://developers.facebook.com/docs/plugins/" data-layout="button_count" data-size="small"><a target="_blank" href="https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2Fplugins%2F&amp;src=sdkpreparse" class="fb-xfbml-parse-ignore">Share</a></div>

But it's hard coded 1 URL. I need to add get_permalink() for the post URL and get_the_post_thumbnail_url() for the featured image but not sure how to do this in PHP.

I can work out the data-href using get_permalink() but can't get the post thumbnail working.

I did output the ig tabs within the head tags like this

printf( '<meta property="og:url" content="%s" />', get_permalink() );

printf( '<meta property="og:image" content="%s" />', get_the_post_thumbnail_url( get_the_ID(), 'full' ) );

When i use this code it works but it doesn't include the image

'<div class="fb-share-button" data-layout="button_count" data-size="large"></div>';

Is there a way to add the single post URL and featured image in PHP using sprintf?

Works, the only problem was when using local it doesn't.
