0 score not being passed back

[kreut]

Hi,

When a student receive a 0 and I pass the score back to Canvas, nothing actually gets passed back, making it look like it is something that needs to be graded (Bug report posted here: ).

As a possible fix, in https://github.com/IMSGlobal/lti-1-3-php-library/blob/master/src/lti/LTI_Grade.php:

$score_given = 0 + $this->score_given;
$grade_array = array_filter([
"scoreGiven" => $score_given,
"scoreMaximum" => 0 + $this->score_maximum,
"comment" => $this->comment,
"activityProgress" => $this->activity_progress,
"gradingProgress" => $this->grading_progress,
"timestamp" => $this->timestamp,
"userId" => $this->user_id,
"submissionReview" => $this->submission_review,
]);
if (!$score_given) {
$grade_array['scoreGiven'] = 0;
}

Use https://github.com/packbackbooks/lti-1-3-php-library instead, it fixes this and multiple other issues and this repo here is dead.
