Mods & Plugins (Requests & Discussions) / [MOD]-BETA Whole/part category download
« on: January 08, 2003, 01:58:45 AM »
This mod will let visitors download all images from a category.
Almost the same as Lightbox, exept that it will download pictures that are desplaeyed on one page (u can see what I mean here look at ZIP button near UPLOAD).
Why is it BETA? - because I've tested only on my own server/system, and it didnt work well with too many images or too big filesizes. It might be because of wrong my server configuration....dont know....
so, anyway.
1. Open categories.php file.
1.1. Find:
2. Open download.php file.
2.1 Find:
3. Open /templates/yourtemplate/categories.html
3.1. Add {download_button} anywhere u want.
If u wish make it without limitation (download whole category) then u'll need change code:

1.1. Find:
Code: [Select]
$site_template->register_vars(array(
"msg" => $msg,
Replace with:Code: [Select]
if (!check_permission("auth_download", $cat_id)) {
$download_button = "<img src=\"".get_gallery_image("download_zip_off.gif")."\" border=\"0\" alt=\"\" /></a>";
}
else {

}
$site_template->register_vars(array(
"download_button" => $download_button,
"msg" => $msg,
2. Open download.php file.
2.1 Find:
Code: [Select]
$user_access = get_permission();Add after:Code: [Select]
include(ROOT_PATH.'includes/page_header.php');
if (!function_exists('get_file_data'))
{
function get_file_data($filename)
{
return file_get_contents($filename);
}
}2.2. Find:Code: [Select]
else {
echo $lang['download_error']."\n<!-- EMPTY FILE PATH //-->";
exit;

Add after:Code: [Select]

header("Location: ".$site_sess->url($url, "&"));
exit;
}
}
}3. Open /templates/yourtemplate/categories.html
3.1. Add {download_button} anywhere u want.
If u wish make it without limitation (download whole category) then u'll need change code:
Code: [Select]
ORDER BY ".$config['image_order']." ".$config['image_sort']."
LIMIT $offset, $perpage"; with this:Code: [Select]
ORDER BY ".$config['image_order']." ".$config['image_sort']."";
if u want limit downloaded pictures to your own desired number, change:Code: [Select]
LIMIT $offset, $perpage"; to this:Code: [Select]
LIMIT $offset, X"; where X is number u want.
?
and if u use some download manager it may start downloading the image instead of showing it.
