Custom block for display of scorm interactions

I have developed custom block which extract scorm interactions, elements like x.start.time, core.cmi.lesson_status My question is whether the result is displayed for logged in users only. Here is my code.

class block_scormtest extends block_base {

    function init() {
        $this->title = get_string('pluginname', 'block_scormtest');
    }
    function get_content()  {
        global $DB;

        if ($this->content  !== NULL) {
            return $this->content;
        }

        $content = '';
      
        $courses = $DB->get_records('scorm_scoes_track', ['element' => 'cmi.core.lesson_status']);
        foreach ($courses as $course) {
            $content  = $course->attempt.  '     '.userdate($course->timemodified, get_string('strftimerecentfull')). '  '. $course->value. '<br>';
        }

     $this->content = new stdClass;
    $this->content->text = $content;
            
    }
         
}

I am new to this LMS development, so I am trying to figure out a few custom blocks. My question again is related to scorm interactions. I have added this sql query

SELECT scc.userid AS User, sct.name AS Name, scc.scoid AS SCORM_ID, sct.module AS Module, scc.value AS Sale_amount, sct.value AS Loan_amount

FROM

(SELECT u.id AS userid, st.scoid AS scoid, st.value AS value

FROM prefix_course AS c

LEFT JOIN prefix_scorm AS sc ON sc.course=c.id

LEFT JOIN prefix_scorm_scoes_track AS st ON st.scormid=sc.id

LEFT JOIN prefix_user AS u ON u.id=st.userid

WHERE st.element='cmi.interactions_0.student_response') AS scc

LEFT JOIN

(SELECT c.fullname Course, sc.name AS module, st.scoid AS scoid, u.id AS userid, u.firstname name, st.attempt as Attempt, st.value AS value

FROM prefix_course AS c

LEFT JOIN prefix_scorm AS sc ON sc.course=c.id

LEFT JOIN prefix_scorm_scoes_track AS st ON st.scormid=sc.id

LEFT JOIN prefix_user AS u ON u.id=st.userid

WHERE st.element='cmi.interactions_1.student_response') AS sct

ON sct.scoid=scc.scoid

AND sct.userid=scc.userid

ORDER BY scc.userid

to generate reports on loan amounts and sale amounts. Now I want to display it in the form of custom block showing only the total loan amount and sale amount by the user that they have made. This is a little tricky. For example: here in this screenshot, for the admin user, the total loan amount should be 17800 and sale amount: 116000

enter image description here

Is this possible in any way by using SELECT sum(value) WHERE element='cmi.interactions_0.student_response' sale amount= sum of student response

thanks for this Russell.

I'm looking to edit the logic so that the logged in user can only see the records that they themselves have created for scorm interactions(x.start.time, cmi.interactions_0.student_response, cmi.interactions_1.student_response, cmi.core.lesson_status)

Thanks again for looking into it.

You'll need to specify the user id if you want a specific user

Add the global $USER object at the top eg:

global $DB, $USER;

Then use something like this for the SQL - this is for elements containing cmi.core.lesson_status or x.start.time

[$elemsql, $elemparams] = $DB->get_in_or_equal(['cmi.core.lesson_status', 'x.start.time'], SQL_PARAMS_NAMED);

$sql = "SELECT sst.id, c.id AS courseid, c.fullname AS coursename, s.id AS scormid, s.name AS scormname, sst.attempt, sst.element, sst.value
        FROM {scorm_scoes_track} sst
        JOIN {scorm} s ON s.id = sst.scormid
        JOIN {course} c ON c.id = s.course
        WHERE sst.userid = :userid
        AND sst.element {$elemsql}";

$params = array_merge(['userid' => $USER->id], $elemparams);

$scoes = $DB->get_records_sql($sql, $params);
