I try to better explain ...
HTTP works like this: you ask something, you receive something, html and
texts are just one option.
Got it so far
Your example page mess up html, zip, everything, because when you
download a file you still have the rest of the page sent in the output.
Nops, not really.
index.php:
print stuff
do stuff
open download.php in a _new_ window.
print more stuff
page end
this should be possible, right? Two different headers for two different
pages.
A download should have ONLY file related info/headers and nothing else
in the output ... echo/print in the middle of the code before an header
is an error, everything in output before an header is an error,
everything after headers that is not related to that header is an error,
got my point?
Jep! And that's actually what I do. What I could, is to add exit; after
the headers have been sent and the file have been pushed. I do an update
of the database to tell the system that the files in the zipfile has
been downloaded.
To decide how a page should behave, you must be able to do not produce
anything except the expected output with expected headers, that's why I
have said headers are fundamental for a response, we cannot play with
outputs however we want.
The only output is the headers of the zipfile:
header('Accept-Ranges: bytes');
header("Content-Type: application/zip");
header("Content-Length: $size");
header("Content-disposition: attachment;
filename=\"".basename($zip_filename)."\"");
header("Content-Transfer-Encoding: binary");
readfile($filename);
// we need to reload top5 to have a current view
unset($_SESSION['top5']);
$_SESSION['reload_top5'] = 1;
// NOTE second param shall be an array, not a variable when
downloading zip files
download_completed($member_id, $downloaded_version_ids);
Wouldn't you say this is okay?
As summary, once you have created and tried a dedicated page without a
single white space or print before, during, or after the dedicated
download stuff, I'll try to understand where is the error.
Otherwise it could be everything, and I am against "magic behaviors" ...
you need to download? Well, create a file which aims id to download and
nothing else, or you gonna constantly find these kind of problems in
your applications.
I believe the testpage does forfill that request? Or do you mean otherwise?
Kind regards
Kim
