A JSON-encoded object containing the text of the post, relevant links, a media type (image, mp3, flash), as well as any other key/value pairs you may want to add. Note: If you want to use this call to update a user's status, don't pass this parameter. See Updating a User's Status above.

The message the user enters for the post at the time of publication. If the message is a status update (that is, you're not including an attachment or an action link), it can contain up to 420 characters. Otherwise, if the post contains an attachment or action link, the message can contain up to 10,000 characters.

An object that defines the privacy setting for a post, video, or album. Only the user can specify the privacy settings for the post.

The ID of the user, Page, group, or event where you are publishing the content. If you specify a target_id, the post appears on the Wall of the target profile, Page, group, or event, not on the Wall of the user who published the post. This mimics the action of posting on a friend's Wall on Facebook itself. Note: If you specify a Page ID as the uid, you cannot specify a target_id. Pages cannot write on other users' Walls. Note: You cannot publish to an application profile page's Wall.

The ID of the user or Page publishing the post. If this parameter is not specified, then it defaults to the session user. If you want to publish as page, you should use the 'enable_profile_selector' option with FB.login. This option enables the profile selector on the permission dialog. Note: If you specify a Page ID as the uid, you cannot specify a target_id. Pages cannot write on other users' Walls.
