title: Adding a URL hash into meta data for Facebook and Twitter share cards
body: <p>I am looking to use a hash that is given in through a URL (www.example.com/index.html#myhash) and use it in the page's metadata that Facebook and Twitter can then retrieve to make a share card like this: <a href="https://dev.twitter.com/docs/cards/types/photo-card" rel="nofollow">https://dev.twitter.com/docs/cards/types/photo-card</a>. Is this possible? Or would it be better to just use a PHP $_GET[] variable? I'm trying to keep the page static so the hash would be ideal, but I'm fairly sure I can't dynamically create the meta tag with JS because Twitter and Facebook will not execute that code. Thanks for help!</p>
