FN-FORUM: PHP download script part 2

date posted 28th January 2008 08:40

Hi all,

Many thanks for all your help on my last posting. I have tried
everything that was suggested, but to no avail.

I decided to go the compressed file route, my download script now
compresses the file into a zip file. If I access the zip file via FTP, I
can download the file and extract the contents without any problems.
However whenever I download via the script I get the following error:

[/home/steven/Desktop/BNK1.jpg.zip]
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
zipinfo: cannot find zipfile directory in one of
/home/steven/Desktop/BNK1.jpg.zip or
/home/steven/Desktop/BNK1.jpg.zip.zip, and cannot find
/home/steven/Desktop/BNK1.jpg.zip.ZIP, period.

(I'm using Archive Manager in Gnome)

The download code is below.

function download_file()
{
if ($this->options['inmemory'] == 0)
{
$this->error[] = "Can only use download_file() if archive is
in memory. Redirect to file otherwise, it is faster.";
return;
}
switch ($this->options['type'])
{
case "zip":
header("Content-Type: application/zip");
break;
case "bzip":
header("Content-Type: application/x-bzip2");
break;
case "gzip":
header("Content-Type: application/x-gzip");
break;
case "tar":
header("Content-Type: application/x-tar");
}
$header = "Content-Disposition: attachment; filename=\"";
$header .= strstr($this->options['name'], "/") ?
substr($this->options['name'], strrpos($this->options['name'], "/") + 1)
: $this->options['name'];
$header .= "\"";
header($header);
header("Content-Length: " . strlen($this->archive));
header("Content-Transfer-Encoding: binary");
header("Cache-Control: no-cache, must-revalidate, max-age=60");
header("Expires: 0");
print($this->archive);
}
}

This is really doing my head in as approx 6 months ago the script was
working, yet no changes had been made. I'm thinking that it could be the
server as I have copied the code to my local server and it works
flawlessly. The server is hosted by Teclan, does anybody know of any
issues with them?

Best Regards,

Steve
