This function updates a single user in the database. This update can contain multiple pieces of user metadata as an array.

To update a single piece of user metadata, use update_user_meta() instead.

To create a new user, use wp_insert_user() instead.

Note: If current user's password is being updated, then the cookies will be cleared!

Special Note

If $userdata does not contain an 'ID' key, then a new user will be created and the new user's ID will be returned. Since version 3.6 this is no longer the case, but this behavior may be restored in the future. See ticket #16731.

Field Name Description Associated Filter
ID An integer that will be used for updating an existing user. (none)
user_pass A string that contains the plain text password for the user. pre_user_pass
user_login A string that contains the user's username for logging in. Please note that the function cannot alter this field, since WordPress does not allow usernames to be changed. pre_user_login

user_url A string containing the user's URL for the user's web site. pre_user_url
user_email A string containing the user's email address. pre_user_email
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 dont use and delete the default admin user). pre_user_display_name
nickname The user's nickname, defaults to the user's username. pre_user_nickname
first_name The user's first name. pre_user_first_name
last_name The user's last name. pre_user_last_name

Remember, user_pass should be the plain text password as it will be automatically hashed by WordPress.
