[MOD] Lightbox for GUESTs v1.2
« on: March 27, 2003, 01:44:45 PM »
-------- Overview -----------------
This MOD will let guests add picture to their lightbox, based on sessions + cookies.
u can see it an action here

-------- Known issue -------------
"GUESTs" lightbox is separate from "USERs", that means, that if u add some images to the lightbox, while u are not logged in and then do login, u wont have those images in the lightbox, untill u logged out.

-------- Installation ---------------

Everything I had follow.

but when I click on lightbox link it give me below message.

Error
--------------------------------------------------------------------------------

In order to use the lightbox, you have to register.

P/s: again, the select picture lightbox is WORKING but just when click on the lightbox link to show the fully selected lightbox is not working

Which file I had to refer back?
What's wrong, huh?

     $cookie_expire = ($permanent) ? $this->current_time + 60 * 60 * 24 * 365 : 0;

     $cookie_name = COOKIE_NAME.$name;

     setcookie($cookie_name, $value, $cookie_expire, COOKIE_PATH,  COOKIE_DOMAIN, COOKIE_SECURE);

usualy this error shows when u have some extra space or new line after closing ?> in .php files. check again every file u edited.

strange, everything works just fine for me...exept download button ;)
to fix that, in lightboxes.php find:
Code: [Select]
 if (!empty($user_info['lightbox_image_ids']) && $user_info['user_level'] != GUEST) {
replace with:
Code: [Select]
 if (!empty($user_info['lightbox_image_ids'])) {

Thank's , the fix works fine.
But the first problem continue to persist... may be the problem caused by the cookies ?
