|

*
|
|
* Can be used to update the user's info (see below), set the user's role, and
|
|
* set the user's preference on whether they want the rich editor on.
|
|
*
|
|
* Most of the $userdata array fields have filters associated with the values.
|
|
* The exceptions are 'rich_editing', 'role', 'jabber', 'aim', 'yim',
|
|
* 'user_registered', and 'ID'. The filters have the prefix 'pre_user_' followed
|
|
* by the field name. An example using 'description' would have the filter
|
|
* called, 'pre_user_description' that can be hooked into.
|
|
*
|
|
* The $userdata array can contain the following fields:
|
|
* 'ID' - An integer that will be used for updating an existing user.
|
|
* 'user_pass' - A string that contains the plain text password for the user.
|
|
* 'user_login' - A string that contains the user's username for logging in.
|
|
* 'user_nicename' - A string that contains a nicer looking name for the user.
|
|
* The default is the user's username.
|
|
* 'user_url' - A string containing the user's URL for the user's web site.
|
|
* 'user_email' - A string containing the user's email address.
|
|
* 'display_name' - A string that will be shown on the site. Defaults to user's
|
|
* username. It is likely that you will want to change this, for both
|
|
* appearance and security through obscurity (that is if you don't use and
|
|
* delete the default 'admin' user).
|
|
* 'nickname' - The user's nickname, defaults to the user's username.
|
|
* 'first_name' - The user's first name.
|
|
* 'last_name' - The user's last name.
|
|
* 'description' - A string containing content about the user.
|
|
* 'rich_editing' - A string for whether to enable the rich editor or not. False
|
|
* if not empty.
|
|
* 'user_registered' - The date the user registered. Format is 'Y-m-d H:i:s'.
|
|
* 'role' - A string used to set the user's role.
|
|
* 'jabber' - User's Jabber account.
|
|
* 'aim' - User's AOL IM account.
|

* 'yim' - User's Yahoo IM account.
