Forms: passing data

compspec1

I'm quite new to PHP, but been reading a lot.

I have one big form split into 3 parts.
(Contact.htm - Info.htm - Data.htm)

What I want to do is after collecting data from all three forms, show an confirmation page that has info from all 3 sections.

What is a good way to pass values through forms and retain them for display?

Thanks in advance!

you have 2 choices:

put the values from one form into hidden values in the next form

I'd do something like the following. All data from forms submitted through POST (I assume you're using POST), in addition to being put in global variables if you have register_globals on in php.ini) is put in the associative array $HTTP_POST_VARS. So you could loop through that array and create a bunch of hidden input fields to carry over your data, like so:

foreach ($HTTP_POST_VARS as $name => $value) {
echo '<input type="hidden" name="' . $name . '" value="' . $value . '">
';
}

Then when you submit that form, the variables will again be submitted through POST and you can have the same loop on the next page.

I'm using POST.

foreach ($HTTP_POST_VARS as $name => $value) {
echo '<input type="hidden" name="' . $name . '" value="' . $value . '">
';
}

to add another variable would you put in $value? or some other name?

I don't understand... the code I put there would add hidden input fields for all POST vars...

Your first page doesn't have that loop.

On the second page, keep the inputs that you already have, and add this loop which will write hidden fields for all the inputs from the first page.

The third page will again have the inputs you already have plus this loop again, which will now write hidden fields for all the inputs posted from the second page (the displayed ones plus the hidden ones from the first page).

When the third page is posted it should have all the inputs from all three pages, unless the user skipped a page.
