Question

I’m trying to prepare alternative contet for facebook sharing.
Site is based on flash player (flash is required to enter site) so facebook share shows only:

‘To view this page ensure that Adobe Flash Player version 10.0.0 or greater is installed.’

Is there any possibility to heck if request is send from facebook and display alternative text / thumb image?

I was trying to play with $_SERVER – without result.

Thanks in advance.

According to quora the user agent contains the word facebook in it suprise suprise so you could just do…

if (stripos($_SERVER['HTTP_USER_AGENT'], 'facebook') !== false) {
  // show html for facebook
}
else {
  // show flash
}
