Stream.addLike
From Facebook Developer Wiki
Contents |
Description
This method lets a user add a like to any post the user can see. A user can like each post only once.
Desktop applications must pass a valid session key, and only the user associated with that session key can like the post. Otherwise, the specified user can like the post.
In order for your user to like a post, the user must grant your application the publish_stream extended permission.
Parameters
| Required | Name | Type | Description | |
| optional | session_key | string | The session key of the logged in user. The session key is automatically included by our PHP client. Desktop applications must pass a valid session key (and have been granted the publish_stream extended permission); other applications need only the publish_stream extended permission. | |
|---|---|---|---|---|
| uid | string | The user ID of the user who likes the post. If this parameter is not specified, then it defaults to the session user. Note: This parameter applies only to Web applications and is required by them only if the session_key is not specified. Facebook ignores this parameter if it is passed by a desktop application. | ||
| post_id | string | The ID of the post. |
Example Requests
$facebook->api_client->stream_addLike(post_id,<uid>);
Response
This method returns true on success, or false and an error code if it fails.
Error Codes
| Code | Description | |
| 100 | Invalid parameter. | |
|---|---|---|
| 102 | Session key invalid or no longer valid (if it's a desktop application and the session is missing). | |
| 200 | Permissions error. The application does not have permission to perform this action. | |
| 210 | User not visible. The user doesn't have permission to act on that object. |
Notes
You can call this method using a session secret, and not the application secret (for example, for a Facebook Connect site or desktop application).
