I am running moodle 2.9.2+. I think, I have found a way to change Maximum Number of Uploaded Files in Assignment. The site give a limitation only 20 files, but I need to give a space for 30 uploaded file, just for very very special case.
The setting was saved in database: mdl_config_plugins > [plugin] assignsubmission_file> [name] maxfiles > [value] 20
All we need to do is only change the value. Don't change manually using phpmyadmin or something else, because it will not make any effect, instead, use moodle function set_config
the function is:
set_config($name, $value, $plugin);
so... the code
set_config('maxfiles', 30, 'assignsubmission_file');
Execute in any php files within moodle folder after require_once(__DIR__ .'/../../config.php');
Thats all.... All Praise for Allah... The Creator and Sustainer of The Universe
