Batch Downloader fails when using piwigo as Docker Image

[PaulSpa]

Environment

• Piwigo Version 14.5.0
• BatchDownloader Version 14.a
• Docker image linuxserver/piwigo or scr.io/linuxserver/piwigo:latest
  This issue does not appear, if Piwigo is installed via the manual installation instructions

Symptoms

• After requesting the zip file by the cloud button of Batch Downloader the browser reports an HTTP Error 500
• In the nginx error.log messages like the following appear:

2024/09/28 11:29:08 [error] 294#294: *7179 FastCGI sent in stderr: "PHP message: PHP Warning: include(../../include/common.inc.php): Failed to open stream: No such file or directory in /config/www/plugins/BatchDownloader/download.php on line 3; PHP message: PHP Warning: include(): Failed opening '../../include/common.inc.php' for inclusion (include_path='.:/usr/share/php83') in /config/www/plugins/BatchDownloader/download.php on line 3; PHP message: PHP Fatal error: Uncaught Error: Call to undefined function check_status() in /config/www/plugins/BatchDownloader/download.php:5

Not your fault but others might see the same issue

I am aware, this is not directly a Batch Downloader issue, but caused by the set up of the docker image. But many Piwigo administrators do use docker to run Piwigo and might interprete this as a Batch Downloader issue first.

I also reported this to the maintainer of the Piwigo docker image.

Workaround

Adjust the path in to the plugin/BatchDownloader/download.php script:

<?php
#define('PHPWG_ROOT_PATH', '../../');
define('PHPWG_ROOT_PATH', '/app/www/public/');
include(PHPWG_ROOT_PATH.'include/common.inc.php');
[...]

After this change the issue does not exist anymore in this environment.
