[MOD] Lightbox Limit for version 1.7.6
« on: January 17, 2009, 05:46:47 PM »
MOD Lightbox Limit for version 1.7.6

This mod allows you to limit the size of all users lightboxes by either total number of images or size of download zip file

This mod does not work on Remote files, I do not use them on my site and have not had the time to research that part of it.
NOTE:  the notes with BIG folder references in the function file, you need to change the /big/ to whatever you are using for your big folder.
            if you are not using a big folder mod, it should just skip that code and continue if it does not find a big folder.

I do not know if it will work on older version or not.

Please backup the following files and your database so things can be fixed easly in case something goes wrong

Modified files include
lightbox.php
globals.php
includes/functions.php
lang/english/main.php
Your template/lightbox.html

also you will need to run the attached lightbox_limit_install.php file in the root of your 4images gallery so it can add the new field to your lightbox database
or you can add it yourself by running this command in your phpadmin
Code: [Select]
ALTER TABLE `4images_lightboxes` ADD `lightbox_file_size` INT(11) NOT NULL DEFAULT '0'Make sure you delete the lightbox_limit_install.php file from your root folder after you run it!

The changes that need to be made in the functions file was tricky and mistakes can be made easly,
so I am just having you replace the entire lightbox functions with the ones I modified.
If you have other mods inside these functions, (add_to_lightbox, remove_from lightbox, clear_lightbox)
you may want to look at my replacing functions file and just put my mods inside of your files,
all my modified lines have "\\ Mod Lightbox Limit" labeled on them.

in includes/functions.php

search for...
Code: [Select]
function add_to_lightbox($id) {
  global $user_info, $site_db;
  $id = intval($id);
  if (!$id) {
    return false;
  }
  $lightbox_ids = $user_info['lightbox_image_ids'];
  $lightbox_array = explode(" ", $lightbox_ids);
  if (!in_array($id, $lightbox_array)) {
    $lightbox_ids .= " ".$id;
  }
  $user_info['lightbox_image_ids'] = trim($lightbox_ids);
  $user_info['lightbox_lastaction'] = time();
  $sql = "UPDATE ".LIGHTBOXES_TABLE."
          SET lightbox_lastaction = ".$user_info['lightbox_lastaction'].", lightbox_image_ids = '".$user_info['lightbox_image_ids']."'
          WHERE user_id = ".$user_info['user_id'];
  return ($site_db->query($sql)) ? 1 : 0;
}

function remove_from_lightbox($id) {
  global $user_info, $site_db;
  $lightbox_array = explode(" ",$user_info['lightbox_image_ids']);
  foreach ($lightbox_array as $key => $val) {
    if ($val == $id) {
      unset($lightbox_array[$key]);
    }
  }

function clear_lightbox() {

  }
}

in Lightbox.php file

search for
Code: [Select]
$site_template->register_vars(array(
  "msg" => $msg,

insert before
Code: [Select]
// Mod Lightbox Limit
$zip_file_size = round(($user_info['lightbox_file_size']/1048576),1);
// End Mod Lightbox limit

search for
Code: [Select]
  "lang_lightbox_lastaction" => $lang['lighbox_lastaction'],
 

insert after
Code: [Select]
// Mod Lightbox Limit
  "zip_file_size" => $zip_file_size,
  "lightbox_max_number_images" => $lightbox_max_number_images,
  "lightbox_max_file_size" => $lightbox_max_file_size,
  "lang_lightbox_max_img_1" => $lang[lightbox_max_img_1],
  "lang_lightbox_max_img_2" => $lang[lightbox_max_img_2],
  "lang_lightbox_max_zip_1" => $lang[lightbox_max_zip_1],
  "lang_lightbox_max_zip_2" => $lang[lightbox_max_zip_2],
// End Mod Lightbox Limit

in global.php file
NOTE: this is where you will set your limits for the lightboxes

Search for
Code: [Select]
?>
insert before
Code: [Select]
// Mod Lightbox Limit
$lightbox_max_number_images = 30; //set to 0 for no limt
$lightbox_max_file_size = 15; // is in MB, set to 0 for no limit
// End Mod Lightbox limit

the next 2 files to be modified are not necessary unless you want the limits posted on your lightbox pages.
See attached screenshot.jpg if you want to decide if you want to see this or not.

in lang/english/main.php file

search for
Code: [Select]
?>
insert before
Code: [Select]
// Mod Lightbox Limit
$lang['lightbox_max_img_1'] = "(You can choose up to ";
$lang['lightbox_max_img_2'] = " items for your lightbox)";
$lang['lightbox_max_zip_1'] = " Meg zip file is maximun allowed.<br>Your current zip file size is around ";
$lang['lightbox_max_zip_2'] = " Megs";
// End Mod Lightbox Limit

This mod may depend on your own template, this is just a reference for placing...
in template/lightbox.html file

search for
Code: [Select]
<b class="title">{lang_lightbox}</b>
replace with
Code: [Select]
<b class="title">{lang_lightbox}</b>{if lightbox_max_number_images} {lang_lightbox_max_img_1}{lightbox_max_number_images}{lang_lightbox_max_img_2}{endif lightbox_max_number_images}
search for
Code: [Select]
<td align="right">{download_button}
replace with
Code: [Select]
<td align="right">{download_button}{if lightbox_max_file_size}<br>{lightbox_max_file_size}{lang_lightbox_max_zip_1}{zip_file_size}{lang_lightbox_max_zip_2}{endif lightbox_max_file_size}
The only drawback to this mod is that if you reach the limit it just shows "error adding image" on page refresh...
But if you are like me and using V@no MOD Add/Remove image to/from lightbox without page refresh http://www.4homepages.de/forum/index.php?topic=5321.0
all you will get when limit reached is "you are unable to check the checkbox"
I have added in the // area the words "would like to see" where I feel a dialog or something should popup and tell the user they reached the limit on thier lightbox but I have tried a few tricks I know and they did not work.
Hopefully someone else can add to this mod and really make it nice!

I want to thank everyone that PMed me with ideas and the help along the way, I just took all the ideas and cleaned things up and made it look as good as I could.
Enjoy!
