header location and redirect

[Bob Bedford]

From my record insertion page I do, in some cases, this:

header("Locatio n: http://$SERVER_NAME/mainpage.php?SI D");

problem is that the mainpage.php doesn't takes new datas. I've to refresh
the page to see the new inserted record.

doing this:
header("Refresh : 0; URL=http://".$_SERVER['HTTP_HOST']."/mainpage.php?SI D);

isn't considered a good alternative.
I want to redirect to the mainpage.php with refreshed datas.

How to do so ? may I keep Refresh header command or it will not work on some
browser ?

What is going on in mainpage.php? Are you sure the record insertion page
really does what you expect? Checked for errors??

If you start your scripts with the code below, you usually get some
hints ;)

ini_set('error_ reporting', E_ALL);
ini_set('displa y_errors', TRUE);

That's the default setting for most PHP installs: to tell the browser not
to cache the page. Though I don't think that's the problem, you can play
around with this headers in mainpage.php:


header('Last-Modified: ' . gmdate('D, d M Y H:i:s', time()-86400*365*10) . ' GMT');
header('Expires : ' . gmdate('D, d M Y H:i:s', time()-86400*365*10) . ' GMT');


// HTTP/1.1
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: post-check=0, pre-check=0', FALSE);

// HTTP/1.0
header('Pragma: no-cache');


BTW, be aware that whatever comes after header() is also executed unless you exit().

mainpage.php does show the list of inserted records for a registered user.
The record is actually inserted for sure, as when I do a refresh, then the
new record is there.
