Custom Certificate plugin: Fix bug for certificates with learnpath index as content type

[juancp-contidosdixitais]

The certificate generation for certificates with learnpath index as content type is actually broken.

If we use this option, the custom certificates plugin code will attempt to instantiate a new LearnpathList object by passing a course code instead of a course_info array.

$courseCode = api_get_course_id();

	if (empty($courseCode)) {
	$courseCode = isset($_REQUEST['course_code']) ? Database::escape_string($_REQUEST['course_code']) : '';
	$courseInfo = api_get_course_info($courseCode);
	if (!empty($courseInfo)) {
	$courseId = $courseInfo['real_id'];
	}
	} else {
	$courseInfo = api_get_course_info($courseCode);
	}

	$studentId,
	$courseCode,
	$sessionId,
	null,
	false,
	$categoryId
	);

* @param array $courseInfo Optional course code (otherwise we use api_get_course_id())

Lines 39 to 52 in 69d982f

	public function __construct(
	$user_id,
	$courseInfo = [],
	$session_id = 0,
	$order_by = null,
	$check_publication_dates = false,
	$categoryId = null,
	$ignoreCategoryFilter = false,
	$ignoreLpVisibility = false,
	bool $includeSubscribedLp = true
	) {
	if (empty($courseInfo)) {
	$courseInfo = api_get_course_info();
	}

This PR fixes the issue by instantiating a new LearnpathList with the correct parameters. Additionally, the description of the LearnpathList constructor for the $courseInfo parameter has been corrected
