I input password "123" into memberPw1, 2 "password wrong." is printed.

And I input ID "1234" that is alreay exist in DB server, "you can use this ID." is printed

In chome browser those functions works well.

What is the problem??

Idcheck.php

If I input "1234" php have to send 'red'=>'bad' to phone. And it must be printed "you can't use this ID.". But it's not.
