I'm not sure why you can't use the header function after a database
query. Doing a query doesn't send any HTTP headers to the browser by
itself. I'd say look at the structure of your script and page. You can
probably do it better where you can use header() in your script.

For example:

$sql = "UPDATE download_count SET download_count='whatever'";
header("Location: downloadprogram.php");

That should work with no problems.

Yes. I first make as you say but late I make page with additional info
like alterntive message with link for manual download and also another
useful info. And this page include header. Therefore a can't use
header() in this page.
It sounds like your flow planning needs some work.  You need to make a
decision as to what you want to do - put out messages(s) or redirect. As
you found, you can't do both.

However, you should be able to make a decision BEFORE either is done, then
do one or the other.

All working. I have are messagess and redirect but I have one qestion:
Is was any error in some browser if I put meta reload not to head of html?

Thank you! :-)

Not a PHP question - you need to ask in alt.html.

But I still say you need to straighten out your code.  Correctly
implemented, there is no need for a meta refresh.

Yeah sounds like the flow is at issue here. It might work if you do
the sql script before redirecting to the message page and have the
message page automatically prompt for download using javascript... and
for if it doesn't auto-prompt (jscript is disabled in browser, etc.)
that page also has a link that allows manual download. At this point,
why do you need meta refresh? ... If you were to direct to the
download first and wanted it to only go to the direct-link page if the
download fails that's a whole other issue, but the only thing I can
think of you needing a refresh (which wouldn't utilize a meta refresh
anyway).
