Function Reference/wp update user

Description

Update a user in the database.

It is possible to update a user's password by specifying the 'user_pass' value in the $userdata parameter array.

If $userdata does not contain an 'ID' key, then a new user will be created and the new user's ID will be returned.

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

Note: Use the wp_insert_user function to create a new user.

Usage

<?php wp_update_user$userdata ?>

Parameters

$userdata
(array) (required) An array of user data.
Default: None

Return Values

UserID (integer) 
The updated user's ID.

Examples

Below is an example showing how to update a user's Website profile field

<?php
require_once( ABSPATH . WPINC . '/registration.php');
$user_id = 1;
$website = 'http://wordpress.org';
wp_update_user( array ('ID' => $user_id, 'user_url' => $website) ) ;
?>

Notes

Please note that we cannot change the usernames through this function, in fact the usernames cannot be changed from the admin dashboard as well since WordPress does not allow the usernames to be updated.

The $userdata array can contain the following fields
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. pre_user_login
user_nicename A string that contains a URL-friendly name for the user. The default is the user's username. pre_user_nicename
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
description A string containing content about the user. pre_user_description
rich_editing A string for whether to enable the rich editor or not. False if not empty. (none)
user_registered The date the user registered. Format is Y-m-d H:i:s. (none)
role A string used to set the user's role. (none)
jabber User's Jabber account. (none)
aim User's AOL IM account. (none)
yim User's Yahoo IM account. (none)
show_admin_bar_front Show the WP admin bar on the front-end. (none)

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