On my website, Like buttons are generated dynamically. The URLs associated with these Like buttons are links that automatically redirect (with htaccess) to its respective hashtag url (i.e. “.com/event/200” redirects to “.com/#event/200”). The issue is that I can’t seem to set the title or image. When a page loads with a hashtag, a database is queried and then the page title, meta data, and other things are changed. Facebook seems to be using the metadata that’s set before the database has had time to load and the content has been changed. Does anyone have any idea how I can solve this problem? I’d love to be able to set the title and image when the like button is loaded if there’s anyway to do that. Here’s my like button code:
<fb:like href='http://website.com/"+postname+"/"+data.id+"' send='true' layout='button_count' width='450' show_faces='true'></fb:like>
That’s your error right there.
Since the Hash part of an URL does not get transmitted to the server, it’s only usable client-side. So redirecting to it server-side is a really bad idea, since you know nothing about the client’s capabilities (f.e. if it supports JavaScript).
Don’t do server-side redirects – make them client-side instead, via JS.
