Facebook Graph API - delete like

Question

I\'m developing an app for Facebook in PHP, part of which lists the user\'s \"likes\". I would like to add a link next to each like so that the user can manage their likes b

Answer 1

It's not the 'like' that has an ID, it's the post - which is why the api call uses '/POST_ID/likes' as a target - if you delete '/POST_ID', it'll get rid of the post, but if you delete '/POST_ID/likes' it'll get rid of the user's 'like' for that post.

Answer 2

With OpenGrpah, likes do have ids, it is the single id field in the object returned by an API call to og.likes.

Answer 3

Likes do have an ID.

If you look at https://graph.facebook.com/me/likes, you will see that the resulting data does contain an ID value for each.

{
   "data": [
      {
         "name": "Audi",
         "category": "Consumer_products",
         "id": "96585976469",
         "created_time": "2010-09-27T15:30:15+0000"
      }
    ]
}

You might want to try the ID's there, I've noticed that the FB API doc sometimes has errors.

Edit: I think this also may be a terminology issue, as what the doc says doesn't have ID's is probably likes to a user post, and these probably don't really have an ID and can be removed by issuing a delete to the POST_ID/likes. Then there's the likes generated by liking pages and/or external websites via the like-button, and these DO have an ID. Confusing, it is.

Answer 4

You unlike using access_token which used to make this like.

Pseudocode:

to like:

FacebookGraphApi::getInstance()->setAccessToken('xxx')->post('xxxxxx/likes')

to unlike:

FacebookGraphApi::getInstance()->setAccessToken('xxx')->delete('xxxxx/likes')

Answer 5

Yes, likes don't have an ID in the Graph API. You like or unlike an item by POSTing or DELETEing to {item_id}/likes, where {item_id} is replaced by the ID of the object you're liking/unliking.

To find out what the current user has liked (so you can delete them appropriately), you can use the "likes" connection of the User object (docs). So, if you request http://graph.facebook.com/me/likes, you'll get a list of pages/people/whatever that a user has liked. (Note: this does not include posts or photos or things like that)

This will return an array of data full of items like this:

{
     "name": "Very Hungry Caterpillar",
     "category": "Artist",
     "id": "29956247793",
     "created_time": "2009-03-27T15:48:29+0000"
}

The ID in there is not the ID of the like. It is the ID of the object that the user has liked, so in order to un-like it, you have to make a DELETE to http://graph.facebook.com/29956247793/likes.
