I am trying to hack the source code for the overview report on our Moodle 2.2 installation so that it will show a cumulative percentage for a student for all enrolled courses. The end result should look something like this:
I am not a programmer and so in the spirit of open source I was hoping a developer or community member would be able to help me with this.
I believe the right place to start is in /grade/report/overview/lib.php and I've found that I can insert echo statements just above line 174:
-> possible insertion point
But I know very little php and figuring out how to make it calculate the sum of the percentages and then average them might be difficult for me but would likely take a developer minutes to figure out.
Any help would be greatly appreciated
