Answer 1

Problem of parenthesis at the end of the syntax, you are closing the VALUES parenthesis but not the mysql_query one:
mysql_query("INSERT INTO users (name, email, username, password, /*birthday,*/ gender, accountType/*, creationDate*/)
VALUES ( '$name', '$email', '$username', '$password',/*STR_TO_DATE('$birthYear,$birthMonth,$birthDay','%Y,%m,%d'),*/ '$gender', '$type'/*, '$today'*/ )")
