Hello,
I have a problem that I'm sure is simple but I have searched the newsgroup
and have not found it posted before so I apologize if it has been asked
heaps of times before.
I have a page that list all current orders from customers. Customers can
order at any time. I have a checkbox beside each listing so that as each
order is complete it can be ticked off. I want the page to refresh every 2
mins so I have added ....
<meta http-equiv="Refresh" content="120" />
this will enable me to see new orders. However I will lose the information
from the check boxes telling me which orders are completed if I have not
pressed the submit button first. Is there a standard way around the
refresh/submit problem? Can anybody offer suggestions?
Thanks for your help.
Noel

<meta http-equiv="Refresh" content="120" />

This meta-tag refreshes the page, but does not submit any form. This does't
work, because the browser (that refreshes the page), cannot know which form
to submit - if any - when there are more then one, so the refresh won't work
for data-submits.

Well, the solution is to write a JScript/JavaScript, that submits the form
every once in a while, and reloads the page this way.

Transfer all the $_POST varaibles to $_GET varaibles will be good enough if
the security requirment is not high...e.g. not using refresh, but redirect
to something like
http://yourhost.com/process.php?step=1&var=1

I suggest you have two frames. Once with boxes you can check, and the
other one listing orders. The one listing orders would have
auto-refresh.

The one with checkboxes would be refereshed only upon hitting the
submit button. This way, you can issue submit at your own leisure
while seeing what new orders are being added.

Another option:
There may be a way with javascript to have a form submit automatically
upon selection of a checkbox. This would obviously slow down the
browser response (due to refresh on every box selection), but it *may*
be another option.

You can submit forms with client-side javascript (people commonly do
it to to use a graphic instead of a submit button in forms).
