Sessions and Back Button

[rmachado]

Hello

I have a registration form divided by three pages. In the first I start a session but only start to register variables in the second (which works correctly). The problem is when I click in the Back Button, and them resubmit the form the variable is not updated.

Does anyone knows what is going on?

Thanks

After you have registered a variable, it cannot be overwritten by php when it transforms the variables from $HTTP_GET_VARS and $HTTP_POST_VARS arrays into global ones.
A quick hack:
$var=$HTTP_POST_VARS["var"];
//where $var is the registered variable.

I want to write a script that will download a php file to my machine. How do I do that.
