I get around this entire problem by not forcing the user to use their
"BACK" button if they've made a mistake at all.
The form itself is the return value of a function, called "print_form()"
or something like that. I have dozens of these functions in my pages,
btw. Anyway, one of the cool things about this is that I can re-use
this function as many times as I need to create this form. So if the
user fails the error-check or the input is invalid, or whatever, I just
execute the function again and the form is displayed.
How do I get the original values back? Well, each in HTML has a
"value" attribute. That's the default value of the input, in the case
of text inputs then the value will be echoed in the text box, et
cetera. In listbox inputs you can use selected="yes" so that the user's
choice is selected. I just put the user's input as the "value" of my
HTML form inputs. Here's an extremely simple example of such a function:
function print_simpleform()
{
$simple_form = "
\n";
return $simple_form;
}
Of course, you can get far more complex and have functions that do this
but use database info as the default values, et cetera. Also, you may
need to "stripslash()" your $_POST data if you have gpc_magic_quotes =
on.
