This helper exists to make it easy to output a URL for a facebook page. Ghost has access two facebook page names/usernames for both users and for the site itself. When used without passing a username, the helper will look for a facebook username in the current template context, and then fallback to using @site.facebook. If there is no facebook username set, the helper will output nothing at all. If you pass a variable or string to the helper, it will concatenate the value with the full url for a facebook page.

Examples

Output the author’s facebook, using an author block: 
{{#foreach posts}}
  {{#author}}
    {{#if facebook}}<a href="{{facebook_url}}">Follow me on Facebook</a>{{/if}}
  {{/author}}
{{/foreach}}
