View 2 RepliesSecurity :: Login Form Using Either User Id Or Email Or Phone Number?
Apr 20, 2010I have to make a login form using vb.net. The login form should either accept
Username ID or
Email ID or
Phone number
---- either of one ,and match it with the password of the corresponding record in the user table.
The user table has following column:- U_ID(varchar),mail(varchar),Phone(Number),Password(Varchar)
The form has two textfields - 1. Username
2.Password
And a submit button. If combination is correct I should be redirected to the Index page.
But I don't have to scan through all the columns of the user table to match the password.
(a)If the user enters user_id say- ID 10012 then we should be able to search only the record in the user_id column as it has alphanumeric or varchar data type and match with corresponding password.
(b)If the user enters Email id we should be able to search through the email id column as email id contains "@ and ." sign.
(c)If the user enters phone number then we should search only the phone column as it has numeric datatype.
