User Object Framework

Provide a framework for assignment of user-object relationship metadata.

Other Notes

Functions provided by this framework include:

  • ucc_uof_object_reference() returns an array of object-integer assignments. Use this to look up the appropriate value for $object_ref based on the object table (wp_posts, wp_comments, wp_users, wp_bp_activity are currently supported) to which you are attaching a user relationship.
  • ucc_uof_add_relationship( $user_id = 0, $user_ip = 0, $object_id, $object_ref ) adds a relationship to the relationship table if none exists and returns the relationship id for that user/object pairing.
  • ucc_uof_delete_relationship( $user_id = 0, $user_ip = 0, $object_id, $object_ref ) will delete a relationship if there are no metadata entries left for that relationship.
  • ucc_uof_get_relationship() returns the relationship id for that user/object pairing.
  • ucc_uof_get_user_id() returns the current user id or 0 if not logged in.
  • ucc_uof_get_user_ip() returns 0 if the current user is logged in, or an ip2long() if anonymous.

Example code:

// Create or get the user-object relationship.
$relationship = ucc_uof_get_relationship( $user_id, $user_ip, $object_id, $object_ref );
if ( empty( $relationship ) )
    $relationship = ucc_uof_add_relationship( $user_id, $user_ip, $object_id, $object_ref );

// Add user_object_meta.
if ( $mode == 'delete' )
    delete_metadata( 'uof_user_object', $relationship, '_your_meta_key' );
else
    update_metadata( 'uof_user_object', $relationship, '_your_meta_key', 'your meta key value' );
