59 | * is present. |
60 | * |
61 | * Can be used to update the user's info (see below) and set the user's role. |
62 | * |
63 | * Most of the $userdata array fields have filters associated with the values. |
64 | * The exceptions are 'role', 'jabber', 'aim', 'yim', |
65 | * 'user_registered', and 'ID'. The filters have the prefix 'pre_user_' followed |
66 | * by the field name. An example using 'description' would have the filter |
67 | * called, 'pre_user_description' that can be hooked into. |
68 | * |
69 | * The $userdata array can contain the following fields: |
70 | * 'ID' - An integer that will be used for updating an existing user. |
71 | * 'user_pass' - A string that contains the plain text password for the user. |
72 | * 'user_login' - A string that contains the user's username for logging in. |
73 | * 'user_nicename' - A string that contains a nicer looking name for the user. |
74 | * The default is the user's username. |
75 | * 'user_url' - A string containing the user's URL for the user's web site. |
76 | * 'user_email' - A string containing the user's email address. |
77 | * 'display_name' - A string that will be shown on the site. Defaults to user's |
78 | * username. It is likely that you will want to change this, for both |
79 | * appearance and security through obscurity (that is if you don't use and |
80 | * delete the default 'admin' user). |
81 | * 'nickname' - The user's nickname, defaults to the user's username. |
82 | * 'first_name' - The user's first name. |
83 | * 'last_name' - The user's last name. |
84 | * 'description' - A string containing content about the user. |
85 | * 'user_registered' - The date the user registered. Format is 'Y-m-d H:i:s'. |
86 | * 'role' - A string used to set the user's role. |
87 | * 'jabber' - User's Jabber account. |
88 | * 'aim' - User's AOL IM account. |
89 | * 'yim' - User's Yahoo IM account. |
