This was created for my own use (and I'm not sure it is really tidy enough to add to contrib), but I thought I'd throw it out here in case anyone else finds it useful (or wants to give it a bit of a tidy and look after it).
It can be downloaded here:
and needs to be unzipped into the 'moodle/grade/report' folder in order to work.
Note: the report is named 'Upload PDF Grades', as it was written to go with my 'uploadpdf' assignment type, but it should work perfectly well with any other assignment types (and can be easily renamed by editing the file: 'updfgrades/lang/en_utf8/gradereport_updfgrades.php' ).
Thanks for sharing your custom assignment grade report.
Even though you mention it's not so tidy, I'd recommend that you consider adding it to the modules and plugins database so that others can find it easily.
Log in as administrator and click on 'notifications' to set up the capabilities.
Then go to a course, click on 'Grades' and choose 'Upload PDF Grades' from the drop-down in the top-left corner.
"Plugin "gradereport_updfgrades" is defective or outdated, can not continue, sorry." error with Moodle 2.0.2+ and MAMP 1.8.4.
That is what you would expect when installing a Moodle 1.9 plugin in Moodle 2.0+.
At some point, I will update this plugin - it won't take too long to do, but it is nowhere near the top of my priority list at the moment.
