when i use the same code again it will open the registration page and allow to me to register but if i hide the e-mail it will give me error that e-mail already registered

i think that if u add error for code used twice , so tell the visitor that u are already use this code , if there is any error plz and u are still not complete registearation , requist another code for your e-mail

and if the visitor that use code for specific e-mail , it will show error msg that he has already registered with this e-mail
