creating a login page

[Mun]

Hello All,

I'm trying to create a login page with Username listbox,password and I have a table which is storing the records for Username and pwd. I'm loading the username values into listbox and when I'm typing the password I want to check with the corresponding password in the database.

Any help is appreciated, thanks.

This could be considered a little dangerous because it means that anyone coming to your page already knows one of the two pieces of information you want, ie the username. Generally it is better to have two text inputs (actually a text input and a password input) and let the user type both because ity is more difficult to break two words than it is one.

However, if you still would like to do this, here is the outline (I actually have done this in the past for a site) minus the part where you validate the password, because this absolutely should not happen on the client. To do so would require you to print out all the passwords into a javascript array, and thus give anyone who knows how to view source complete access to all of your user accounts.

1) Get your recordset from the database with the usernames
2) setup your form for the login
3) write your select tag
4) loop through the recordset writing the usernames between option tags
5) write an end select tag
6) give them a password input box

When they submit this page the next page should connect back to the database and verify that there is a username with that password in the database.

Again, I heavily caution against this method and I am even more strongly against attempting to validate usernames and passwords client-side as described above, enough so that I will not hand out code for it because I don't want anyone picking it up and reusing it unless they truly understand it an the dangers.
