Downloading zip file result in error 500

[robinofe]

After clicking the link to the compressed file, I get an error 500 message. In the the logs i found the following entries:

2023/07/05 20:40:43 [error] 339#339: *629 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 3PHP message: PHP Warning: include(): Failed opening '../../include/common.inc.php' for inclusion (include_path='.:/usr/share/php81') in /config/www/plugins/BatchDownloader/download.php on line 3PHP message: PHP Fatal error: Uncaught Error: Call to undefined function check_status() in /config/www/plugins/BatchDownloader/download.php:5

Piwigo Version: 13.7.0 Batch Downloader: 13.a php: 8.1

no other plugins installed

I run Piwigo on a Docker on unraid. I also installed a second instance with the same result. I have this problem since the Version update with php 8.1.

Help would be really appreciated,

same problem for me. Edge Browser throws error 500, Firefox just a blank page. The zip files are actually created and reside in the corresponding folder on the server, however the browser cannot show them.

I am using the linuxserver.io Docker version with: Piwigo Version: 13.8.0 Batch Downloader: 13.a PHP: 8.1.22

error messages from nginx suggest that the problem is somewhere in download.php not finding the correct path to Piwigo's include folder inside of the Docker container (based of PHPWG_ROOT_PATH).

Challenge: the plugin's php code (i.e. download.php) resides OUTSIDE of the Docker container but it references folders INSIDE the Docker container which come natively with Piwigo (e.g. include/common.inc.php) and OUTSIDE of the Docker container (i.e. the download-archive folder).

Looks like these type of plugins cannot work well with containers,,,,?

Ok, so I found a solution. The problem is indeed the way paths are handled in Piwigo / Extensions when the server resides in a Docker Container and the plugins etc are mounted outside (which they obviously should). The solution is to replace: define('PHPWG_ROOT_PATH', '../../'); with an absolute path $webRoot = $_SERVER['DOCUMENT_ROOT']; $webRootPath = $webRoot.'/'; define('PHPWG_ROOT_PATH', $webRootPath); For this plugin this needs to be done in download.php

Thanks!!

Thanks a lot- that is it! hope this helps someone else too!!
