Add a New User via functions.php

If you are stuck without database or phpMyAdmin access, and cannot reset a password via the WordPress admin, take a look at the following code.

Add it to your theme’s functions.php file, change the details on lines 2-4 (to ones that do not exist for any existing user), and the next time you access the WordPress login screen a new user with administrator permissions will be created and you can log in.

function sv_wp_admin_account(){
	$user = 'Username';
	$pass = 'Password';
	$email = 'email@domain.co.il';
	if ( !username_exists( $user )  && !email_exists( $email ) ) {
		$user_id = wp_create_user( $user, $pass, $email );
		$user = new WP_User( $user_id );
		$user->set_role( 'administrator' );
	} }
add_action('init','sv_wp_admin_account');
