Refreshing a page

Anon

Is there a way to get a page to reload?

Basically I have a page with a load of html, javascript and php. when the user does something wrong and presses submit an error messgae gets set and the page refreshes (the submit calls $PHP_SELF).

The problem is the page comes back but doesn't show the error message unless I press the refresh button on my browser. Can I force a refresh?

You can force a refresh with a meta tag quite easily, but I don't think this is your problem. I think the problem is your code logic....how is your script laid out? where do you check for submit or not and how do you decide what do show? You shouldn't have to call refresh to get this to work...

he meta tag isn't an option because that refreshes after X seconds. The code is below.

The only things in the include files are database connectivity and error messages.
The codeincludes my nasty workaround of calling the page again once the error variable has been set.

Basically the page displays and at the bottom of the screen table is an error message which the default is a space
(try it http:/193.122.28.177/ - doesn't seem to work under netscape at the mo). When submit is clicked, the database is checked and if an error is returned a session variable is set and the screen refreshes. Upon refresh it calls the session and set another variable which displays the error message. But as I said although it gets set I have to press refresh on my browser.

My workaround fixes the problem (but gives another display problem!) however it's not a 'neat' solution. Or at least I don't think it is.
