Title: GZIP/ZLIB + OPEN FROM LOCATION (DOWNLOAD BUTTON)
Post by: Alain on June 17, 2002, 03:44:11 PM

Hi, I've activated GZIP feature in the admin. panel and activated in the PHP.INI the php_zlib.dll module and also installed the Apache GZIP dll module but still the Download ZIP button doesn't appear beside the Download button...? Why?

Also the download button works (save as) but if you choose OPEN FROM THE LOCATION and do not want to save it but open it in your browser directly then it is waiting, waiting... and the Apache web server is then unable to load any picture if I come back to my site. As if the connection couldn't be closed...
If no workaround is possible, how to force the user to download the picture and not ask to open from the location?

Thanks!

Try this:

includes/functions.php
change:

Code: [Select]

$target = (get_cfg_var("safe_mode") == 1 || (!empty($image_row['image_download_url']) && !is_remote_file($image_row['image_download_url']))) ? "target=\"_blank\"" : "";
to:

Code: [Select]

$target = (!empty($image_row['image_download_url']) && !is_remote_file($image_row['image_download_url'])) ? "target=\"_blank\"" : "";


lightbox.php
change:

Code: [Select]

if (get_cfg_var("safe_mode") == 0 && function_exists("gzcompress") && function_exists("crc32")) {
to:

Code: [Select]

if (function_exists("gzcompress") && function_exists("crc32")) {


download.php
change:

Code: [Select]

if (empty($user_info['lightbox_image_ids']) || get_cfg_var("safe_mode") == 1 || !function_exists("gzcompress") || !function_exists("crc32")) {
to:

Code: [Select]

if (empty($user_info['lightbox_image_ids']) || !function_exists("gzcompress") || !function_exists("crc32")) {

and change:

Code: [Select]

if (get_cfg_var("safe_mode") == 1 || $remote_url) {
to:

Code: [Select]

if ($remote_url) {

Title: GZIP
Post by: Alain on June 18, 2002, 12:55:36 AM

Could you give a step-by-step instruction to install this GZIP support with Apache/PHP?
I've totally switched to the normal Apache/PHP/MySQL system but this button will never show up!!!

Title: Forced download
Post by: Alain on June 18, 2002, 01:16:09 AM

I managed to force the download of the picture otherwise if you choose 'Open from location' then it was bugging my web server.



$dlext = ".pix";

if (!empty($file['file_data'])) {
  if (eregi("MSIE", getenv("HTTP_USER_AGENT"))) {
    $disposition = ($action != "zip" && $action != "lightbox") ? 'attachment' : 'inline';
    header("Content-Disposition: $disposition; filename=".$file['file_name']."$dlext\n");
    header("Content-Type: application/x-ms-download\n");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Pragma: public");
  }
  elseif (eregi("Opera", getenv("HTTP_USER_AGENT"))) {
    header("Content-Disposition: attachment; filename=".$file['file_name']."$dlext\n");
    header("Content-Type: application/octetstream\n");
    header("Cache-Control: no-cache");
    header("Pragma: no-cache");
  }
  else {
    header("Content-Disposition: attachment; filename=".$file['file_name']."$dlext\n");
    header("Content-Type: application/octet-stream\n");
    header("Cache-Control: no-cache");
    header("Pragma: no-cache");
  }
  header("Last Modified: ".gmdate("D, d M Y H:i:s")."GMT\n");
  header("Expires: 0\n");
  header("Content-Length: ".$file['file_size']."\n");

  if (eregi("Mac", getenv("HTTP_USER_AGENT"))) {
    header("Content-Transfer-Encoding: binary\n");
    header("Accept-Ranges: bytes\n");
    header("Connection: close\n");
  }
  echo $file['file_data'];
}

The extension .pix is added to make it viewable only if already downloaded  :o

Title: Cool!
Post by: Alain on June 18, 2002, 01:30:02 AM

It works now, I thought I shouldn't use the full path to the PHP/ZLIB extension. The lightbox ZIP download is xtra!

I still have this problem when you choose 'Open from location' with a picture, it is waiting, waiting... and then nothing appears... The web server is not usable anymore and I have to close the Windows session to make it usable again...  :oops:

hi,

i'm not sure what you mean with "'Open from location'" but maybe this will help

admin/constants.php

// Check existence of remote image files.
// If you choose 1, you could get sometimes timeout errors
define('CHECK_REMOTE_FILES', 1);

Which browser are you using? I tried it with IE 6, Opera 6.01, Mozilla 1.0 RC2, it works well. Only Netscapes (4.7 and 6) want to save the file with the name "download.php", but if you rename it to download.jpg it works ;)
