Hi Eduardo,

Sounds to me like your problem is that you're seeing the browser-cached
version of the original form.  If that's the case, here's a no-cache
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");    // Date in the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
                                                    // always modified
header("Cache-Control: no-store, no-cache, must-revalidate");  // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

I think this is straight out of the PHP.net docs (I have it stored as a
Dreamweaver snippet).  Just place that in your script somewhere before any
other output to the browser.

Hi all.Here's the problem I've got with MySQL:1. Click on a record (through
the PHP software I'm developing) to edit it2. Change some fields3. Submit4.
When back to the same record (just submit it to save changes) all fields are
with old values.5. Press F5 and everything is OK with changed saves.I've
found out that UPDATE is occuring after the new SELECT (or SELECT is
occuring before UPDATE) so that the old values are still returned.My first
idea is to use the values from the from and not from the SELECT (database)
after submit. So I'd get the real values.But I'd like to find out some
database side solution since this is not good at all :(Thanks in
advance,Eduardo Bacchi KienetzSenior Support
