为WordPress中当前登录的用户设置临时变量

Question

If my user can login from different browsers, concurrently, how can I save a temporary variable (a special format random variable or a device specific id) for each session and access it later in codex?

I can't use update_user_meta and get_user_meta, because user meta is user based, not session based.

Answer 1

You could use user meta.

See update_user_meta and get_user_meta .

The current user id can be retrieved with get_current_user_id to set and then get values associated with a given user.

The only gotcha is when using get_user_meta (or any other get meta function in WordPress), is be sure to set $single to true , otherwise you'll get an array with just one value.
