Question

I’m using the Facebook Send Dialog to send messages to friends. As documented here: https://developers.facebook.com/docs/reference/dialogs/send/ and am using a link like the one in Facebook’s example:

https://www.facebook.com/dialog/send?app_id=123050457758183&name=People%20Argue%20Just%20to%20Win&link=http://www.nytimes.com/2011/06/15/arts/people-argue-just-to-win-scholars-assert.html&redirect_uri=http://www.example.com/response

On the page I have specified as the redirect_uri I am displaying text saying: “Your message has been sent”. However I’ve realised that you see this page even if you’ve clicked cancel in the Facebook dialog.

Is there any way to determine whether save or cancel has been clicked?

Update: I’ve found a workaround using the FB.ui method which solves the immediate issue I was having. I would still be interested to know if anyone has a better solution using a Send Dialog link like the one above.

Answer 1

I’ve found a work around by using Facebook’s Javascript SDK’s FB.ui method.

      FB.ui({
          method: 'send',
          name: 'People Argue Just to Win',
          link: 'http://www.nytimes.com/2011/06/15/arts/people-argue-just-to-win-scholars-assert.html,
          display: 'popup'
          });

N.B. display must be set to popup for this to work!

As it does not require a redirect_uri, the issue of knowing whether save or cancel has been clicked is not an issue. If however you do wish to know this, you can access a response object:

      FB.ui({
          method: 'send',
          name: 'People Argue Just to Win',
          link: 'http://www.nytimes.com/2011/06/15/arts/people-argue-just-to-win-scholars-assert.html,
          display: 'popup'
          },
          function(response) {
              if (response){
                  // save has been clicked
              } else {
                  // cancel has been clicked
              }
          });
