How to use grade_get_course_grade(); function? I use this function: 

$resultkrb = grade_get_course_grades(79, null); 

$grd = $resultkrb->grades[2]; 

print_r ($resultkrb);


but I see:


stdClass Object ( [scaleid] => 0 [name] => W całym kursie [grademin] => 0.00000 [grademax] => 100.00000 [gradepass] => 0.00000 [locked] => [hidden] => [grades] => Array egg )

 $courseid_or_ids = null 
)

Re: use grade_get_course_grade();

by Mike Finch -

I am using Moodle version 3.0.2, and I can use grade_get_course_grade() successfully.

I have a user with record ID of 6, and that user is definitely enrolled in several courses.   I execute the following function in my page.

function perform_test()
{
  global $DB;
  $userId = 6;
  $courseId = null;

  $result = grade_get_course_grade( $userId, $courseId );

  if ( is_array( $result ) )
  {
    foreach ( $result as $id => $rec )
    {
      $course = $DB->get_record( 'course', array( 'id' => $id ) );
      print html_writer::tag( 'p', sprintf( "%d: course='%s' grade=%f", $id, $course->fullname, $rec->grade ) );
    }
  }
  else
  {
    print_object( $result );
  }
}

The result returned by grade_get_course_grade() is an array of stdClass objects, where each object has properties such as the following example.

stdClass Object
(
    [grade] => 80.00000
    [locked] => 
    [hidden] => 
    [overridden] => 0
    [feedback] => 
    [feedbackformat] => 0
    [usermodified] => 
    [dategraded] => 1468864667
    [item] => stdClass Object
        (
            [scaleid] => 0
            [name] => Course total
            [grademin] => .00000
            [grademax] => 100.00000
            [gradepass] => .00000
            [locked] => 
            [hidden] => 
        )
    [str_grade] => 80.00
    [str_long_grade] => 80.00 / 100.00
    [str_feedback] => 
)

Thus, I can successfully print the grade of each course the user is enrolled in.  I hope this example helps.

Comparing my output to yours, it seems that your are getting just the sub-object associated with keyword 'item'.  I cannot explain that given your code snippet.


I found this forum post while looking for a way to get the total course grade programmatically.   It was surprisingly difficult to find documentation for that.  I am lucky I came across this post;  it saved me from reverse engineering the grader report.
