I have a php script that is invoked on 2 different occasions:
1) the first to create a page with a form the user will use to input
information for a new table row - this form has method=POST
2) the script is run a second time to accept the input from the
completed form, add the new row to the table on the database, then
create a simple form with an "OK" button the user will click on to go to
another page to view the result of the database maintenance - this form
has method=GET
Everything is working great EXCEPT THAT the url parameter I attempt to
pass on the second form to the php script that displays the database
maintenance never gets there! It's on the second form (<form
method="get" action="bloglist.php?thread=yet%20another%20new%20thread">)
but the bloglist.php script doesn't receive it. The query string is
empty when bloglist.php starts.
Also, another very curious, and perhaps revealing, thing - when I
attempt to view the page source of the second form I mention above, the
one with method=GET, I get the odd, and absolutely nonsensical, message
"The page you are trying to view contains POSTDATA that has expired from
the cache." But this makes no sense, since this second page (with
method=GET) has (or should have) no POSTDATA!?!
Can anyone make any sense of any of this for me? I'm making pretty good
progress in general, but, once again, I seem to have hit a snag here I'm
don't seem to be able to get past.
Thanks for any help you can give me.

Firstly, if you have a form and you are sending it using GET, then why don't you
use a <input type='hidden' name='thread' value='yet another new thread' />
element to send the parameter - that's what input tags are for. I have a feeling
that the "?foo=bar" bit is stripped off a GET request URL if there are other
form elements, although it's not always stripped off a POST... maybe it's
browser-dependent.
Secondly, when you refresh the second form, you are making a POST request -
that's what generated the form in the first place, so you would expect the
message about POSTDATA - and (in Firefox at least), to view the source the
browser repeats the page request, effectively the same as refreshing the page.
If you want to see the source without repeating the POST request, you need to
use something like the WebDeveloper tool bar - it has a View Generated Source
function which extracts the source from the DOM model the browser used to render
the page.
