Checking for event-rsvp status and showing disabled/enabled RSVP-button

Question

I\'m still a bit unsure how I would find this in the documentation, but I\'d like to check whether the logged-in user has RSVP\'ed to an fb-event or not, and show the \"I\'m

Answer 1

Actually, there's an easier way to do all of this. The problem with the FQL query is that there's a delay of like 15-30 seconds after you submit the RSVP for the status to show up. But this works in the graph API without pagination. Try a GET request in this form:

/[event id]/invited?user=[user_id]&access_token=[access_token]

It'll return a data structure with the rsvp_status if the user has RSVPed at all, including for public events where that user wasn't technically "invited." If the data structure is blank, then they haven't RSVPed at all.

Answer 2

You can query the event_member FQL table, something like:

FB.api(
    {
        method: 'fql.query',
        query: 'select rsvp_status from event_member where eid = "EVENT_ID" and uid=me()'
    }, function(response) {
        alert(response[0].rsvp_status);
    }
);

Would return (alert) something like: declined

Answer 3

You can use the Graph API to do this. There are two scenarios that may be of interest: (1) For an event, you want to list if the user is attending, and (2) for a user, you want to list the event's they're attending. You need the user_events permission for both scenarios.

For (1): HTTP GET /EVENT_ID/attending. This will return an array of objects with {id, name, rsvp_status} fields. Look for the User ID you're interested in and, if they've RSVP'd, then the rsvp_status field will tell you if they're attending.

For (2): HTTP GET /USER_ID/events. This will return all the events for the user with several fields, but also {id, name, rsvp_status} fields as above. This time, look for the Event ID you're interested in, and then the rsvp_status field will tell you if the current user is attending, not attending, maybe attending, or hasn't RSVP'd (i.e. rsvp_status is unsure).
