I’m working on a not for profit website, and trying to integrate with facebook. The app seems to work fine, single sign on works fine, even a custom “post to wall” function works fine using the javascript sdk. What does not work, however, is adding a photo to represent the entity, and anything other than default text, when a person clicks on the like button.
What’s worse is there is some ghost text that I personally have never actually seen (other than in the text box itself) that finds its way into the dialog box when posting and leaving the text box empty.
The documentation here falls short:
https://developers.facebook.com/docs/reference/plugins/like/
Open Graph API tags also did nothing.
If you “like” the “like button” you’ll see that their example does exactly what I’m trying to accomplish. There’s a photo and a little description of what the button is. Is it possible to do this on other sites?
I’ve struggled a lot with this myself, but I found that by putting my page’s URL into Facebook’s debugger, it made the correct image, text, etc. show up when clicking a share button.
