From MoodleDocs
Moodle 2.2 This page describes the API used by the Engagement Analytics indicators and reporting mechanisms.
Main info
IMPORTANT This page is a WIP and does not reflect the final state of the engagement analytics API!
Indicator
File Layout
Indicators live in a folder in mod/analytics/indicator. The layout inside this folder follows the typical layout for a Moodle plugin. For example, inside the mod/analytics/indicator/myind folder we would have:
- indicator.class.php
- Defines the indicator_myind class, which should extend the indicator base class.
- renderer.php
- This contains the definition of the analyticsindicator_myind_renderer class, which should extend the analyticsindicator_renderer base class.
- thresholds_form.php
- Defines the analyticsindicator_myind_thresholds_form which contains a function definition_inner for including on the report settings page.
- lang/en/analyticsindicator_myind.php
- English language strings for this indicator. You can, of course, include other languages too. The language file must define at least the string giving the indicator a name, for example $string['pluginname'] = 'My Indicator';
- db/install.xml, db/upgrade.php
- For creating any database tables required, as normal. See #Database_tables below.
- db/access.php
- Defines any capabilities required by this question type. This is very rarely needed.
Functions
Examples
indicator_random
Return a random risk score for each user.
defined('MOODLE_INTERNAL') || die();
require_once(dirname(__FILE__).'/../indicator.class.php');
class indicator_random extends indicator {
protected function get_risk_for_users($userids, $courseid, $startdate, $enddate) {
// TODO: Fill this in.
}
public function get_defaults() {
// TODO: Fill this in.
}
// TODO: Complete class definition.
}
