update_user_option() WordPress Function

The update_user_option() function is used to update a user meta field with new value. The function takes three parameters: the user ID, the meta key to update, and the new value to set. This function is typically used when a user updates their settings on a Wordpress site. For example, if a user changes their display name, the update_user_option() function would be used to update the “display_name” meta key with the new value.

update_user_option( int $user_id, string $option_name, mixed $newvalue, bool $global = false ) #

function update_user_option( $user_id, $option_name, $newvalue, $global = false ) {
	global $wpdb;

	if ( ! $global ) {
		$option_name = $wpdb->get_blog_prefix() . $option_name;
	}

	return update_user_meta( $user_id, $option_name, $newvalue );
}
