I am using moodle 2.6 and i created a link for question bank category option
here is the code:
new moodle_url('/question/category.php',array('courseid' => $COURSE->id))
my problem is, it didnt redirect to the target page and display only blank page.
the output URL is : http://localhost/moodle/question/category.php?courseid
equal sign is also missing .
