Hello,
I need to code a quiz reports subplugin, but the documention is very scantly (https://docs.moodle.org/dev/Quiz_reports).
I tried to define the display() public function, but when visiting http://.../mod/quiz/report.php?id=cmid&mode=name (where "name is something like "my-plugin") I just see the usual report and nothing else.
Could you suggest a simple plugin to study for this kind of activity? Thank you
Try purging caches
Truth is, I had not set the "dev configuration":
$CFG->debug = E_ALL;
$CFG->debugdisplay = 1;
$CFG->langstringcache = 0;
$CFG->cachetemplates = 0;
$CFG->cachejs = 0;
$CFG->perfdebug = 15;
$CFG->debugpageinfo = 1;
