This has been puzzling me and i hope someone can help. I have a MySQL database field that contains a members password "password" and i need a login script that asks for the customers username and 4 random digit's of there password, for example:
Username: [ ]
Digit 2 [ ], Digit 4 [ ], Digit 6 [ ], Digit 8 [ ]
But if there password is only 7 digit's it would be pointless asking for an 8th digit - so i also need help working that out too. If anyone has a code example or could type a quick one up it would be superb.
