download af fil i stedet for visning

Prøv dette:

<?php
/*******************************************************************
  * Force download script:
  * Save this script as i.e. download.php
  *
  * Tested on Mozilla, Netscape 4.78 and 6.21, Internet Explorer 5.5, lynx,
  * Konqueror and Opera. It works fully on all.
  *
  * Usage: download.php?filename=name_of_file.extension
  *
  * Examples:
  * <a href="download.php?data.pdf">Download data</a>.
  * You can also use paths in the filename, as in
  * <a href="download.php?../include/data.pdf">Download data</a>.
  *
  * You can specialise the code by putting a line of the form
  * $filename="data.pdf"; immediately after this comment.
  * This will allow you to send exactly one file for download, viz data.pdf.
  *
  * Only one variable, $filename, is not defined by default. In
  * principle, you can send a the name of the file to download
  * through a POST request (e.g. on a form button). Untested.
  *
  * Restrictions: by default you can't download files with the
  * extensions html, phtml, htm, phtm, inc, php or php3. This is to
  * avoid potential security problems. For example, it is possible
  * to use a PHP file to hide sensitive data such as the password
  * to connect to an SQL server. If we allowed this script to offer
  * php scripts for download, then a client request of the form
  * http://../download.php?sensitive.php could show the raw php file.
  *
  * Security issues: see the comments under Restrictions above. If
  * in doubt, define $filename immediately after this comment and
  * use a separate script for each downloadable file. I've tried
  * using header( "Location: ... " ) to retrieve the file. It doesn't
  * work on a solaris server, but does work on gnu/linux.

takker, det vil jeg prøve det der...

hmm, det lader ikke til at virke...

er det noget du har erfaring med?

pft

der kommer en popup-boks med at Internet Explorer kan ikke indlæse download.php?filename=aa.jpg fra www.splazz.dk

nå, det virker alligevel... mange tak for scriptet..

smid et svar, så får du lige den 50'er :)

go weekend

Undskyld, jeg først svarer nu. Min internetforbindelse har været nede... Men du kan evt. ændre headersne til dette:

  header("Pragma: no-cache");
  header("Expires: 0");
  header("Content-Transfer-Encoding: binary");
  header("Cache-Control: must-revalidate, post-check=0, pre-check=0\r\n");
  header("Content-Type: application/octet-stream");
  header("Content-Type: application/save");
  header("Content-Disposition: attachment; filename=$shortname");
  set_time_limit(0);
  $fh = readfile("$filename");
  fpassthru($fh);

- så får du ikke timeout ved store filer.
Tak i lige måde. :)
