Below is an example showing how to insert a new user with the website profile field filled.


$website = "http://example.com";
$userdata = array(
    'user_login'  =>  'login_name',
    'user_url'    =>  $website,
    'user_pass'   =>  NULL  // When creating an user, `user_pass` is expected.

$user_id = wp_insert_user( $userdata ) ;

//On success
if ( ! is_wp_error( $user_id ) ) {
    echo "User created : ". $user_id;



  • Uses: $wpdb WordPress database layer.
  • Uses: apply_filters() Calls filters for most of the $userdata fields with the prefix 'pre_user'. See description above.
  • Uses: do_action() Calls 'profile_update' hook when updating giving the user's ID
  • Uses: do_action() Calls 'user_register' hook when creating a new user giving the user's ID
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_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

yim User's Yahoo IM account. (none)

If there is no ID, a new user will be created. If you pass an ID , the user with that ID will be updated, and these meta fields are updated if set in $userdata otherwise they are set to null:


When performing an update operation using wp_insert_user, user_pass should be the hashed password and not the plain text password.
