Loading Variables?

Sep 7th, 2007

Hey
I'm having a bit of trouble. I am currently learning php and mysql to access my servers database and collect data. In which i want to use a username and password form. However in the meen time i would like to create one using plain html and javascript. I am quite experienced with javascript, although i have forgotten how to load variables from an external .txt file. Otherwise my users would simply be able to view my source code and see the username and password they need to type.

Any help on this is greatly appreciated

thanks

Well, you would probably have better luck asking this over in the javascript forum, as this one is just Java.

From the php standpoint though, here is a simple login form and verification for a small site I put together for a local grayhound group. Maybe it will help you along:
