How to check if email is busy?

Question

1C-Bitrix

I'm making a user profile page with a form and would like to check if this e-mail is in the database, so that I can then display an error like "This E-mail is already in use." Thank you!

Answer 1

if(\Bitrix\Main\UserTable::getList(['filter' => ['EMAIL' => $email]])->getSelectedRowsCount() > 0) {
    // E-mail существует
}
