Use the password validator function, in the functions.php (code below) to make a name and last name validator function:

function password_validator($password,$len){ $uppercase = preg_match('@[A-Z]@', $password); $lowercase = preg_match('@[a-z]@', $password); $number = preg_match('@[0-9]@', $password); //$specialChars = preg_match('@[^\w]@', $password); if(!$uppercase || !$lowercase || !$number || strlen($password) < $len) { return false; }else{ return true; } }
