An empty template for creating quiz question types with mobile support is available from here
https://github.com/marcusgreen/moodle-qtype_TEMPLATE
There was a presentation on modifying questions type to support the app at the November 2018 developers meeting. You can find a recording of this here
The associated slide show is here. https://docs.google.com/presentation/d/1jUyfULul_g6hh_3s-wISXIVphv_RKqgpHuxMHZ0F800/edit#slide=id.p
The files that need to be modified/added are
db/mobile.php
defined('MOODLE_INTERNAL') || die();
$addons = [
"qtype_YOURQTYPENAME" => [
"handlers" => [ // Different places where the add-on will display content.
'YOURQTYPENAME' => [ // Handler unique name (can be anything).
'displaydata' => [
'title' => 'YOURQTYPENAME question',
'icon' => '/question/type/YOURQTYPENAME/pix/icon.gif',
'class' => ,
],
'delegate' => 'CoreQuestionDelegate', // Delegate (where to display the link to the add-on).
'method' => 'mobile_get_YOURQTYPENAME',
'offlinefunctions' => [
'mobile_get_YOURQTYPENAME' => [],// function in classes/output/mobile.php
], // Function needs caching for offline.
'styles' => [
'url' => '/question/type/YOURQTYPENAME/mobile/styles_app.css',
'version' => '1.00'
]
]
],
'lang' => [
['pluginname', 'qtype_YOURQTYPENAME'], // matching value in lang/en/qtype_YOURQTYPENAME
],
]
];
html template
Your question type will need an html/ionic markup template file that controls how it is displayed at runtime. Ionic markup is based on the Angular template syntax which you can read about here https://angular.io/guide/template-syntax
You can see a real world examples of question type templates at
https://github.com/Beedell/moodle-qtype_oumultiresponse/blob/wip1/mobile/oumr.html and
https://github.com/marcusgreen/moodle-qtype_gapfill/blob/master/mobile/addon-qtype-gapfill.html
(oumr.html is probably a more sensible naming convetion)
Create a file named mobile/addon-qtype-YOURQTYPENAME.html
<section class="list qtype-YOURQTYPENAME-container qtype-YOURQTYPENAME" ion-list *ngIf="question.text || question.text === ">
<ion-item text-wrap class="addon-qtype-YOURQTYPENAME-container qtext">
<core-format-text [component]="component" [componentId]="componentId"
[text]="question.text" (afterRender)="questionRendered()"></core-format-text>
</ion-item>
</section>
The reference to questionRendered() will call the method of that name in the mobile/mobile.js file.
classes/output/mobile.php
This file connects PHP with the html/ionic markup template and the mobile.js javascript which contains most of the runtime logic
namespace qtype_YOURQTYPENAME\output;
defined('MOODLE_INTERNAL') || die();
class mobile {
class mobile {
public static function mobile_get_YOURQTYPENAME() {
global $CFG;
return [
'templates' => [
[
'id' => 'main',
'html' => file_get_contents($CFG->dirroot .'/question/type/YOURQTYPENAME/mobile/addon-qtype-YOURQTYPENAME.html')
]
],
'javascript' => file_get_contents($CFG->dirroot . '/question/type/YOURQTYPENAME/mobile/mobile.js')
];
}
}
mobile/mobile.js
This is where most of the logic is placed such as changing css classes. You can see real world implementations of this file at https://github.com/Beedell/moodle-qtype_oumultiresponse/blob/wip1/mobile/oumr.js
and
https://github.com/marcusgreen/moodle-qtype_gapfill/blob/master/mobile/mobile.js
var that = this;
var result = {
componentInit: function() {
if (!this.question) {
console.warn('Aborting because of no question received.');
return that.CoreQuestionHelperProvider.showComponentError(that.onAbort);
}
const div = document.createElement('div');
div.innerHTML = this.question.html;
// Get question questiontext.
const questiontext = div.querySelector('.qtext');
// Replace Moodle's correct/incorrect and feedback classes with our own.
// Only do this if you want to use the standard classes
this.CoreQuestionHelperProvider.replaceCorrectnessClasses(div);
this.CoreQuestionHelperProvider.replaceFeedbackClasses(div);
// Treat the correct/incorrect icons.
this.CoreQuestionHelperProvider.treatCorrectnessIcons(div);
if (div.querySelector('.readonly') !== null) {
this.question.readonly = true;
}
if (div.querySelector('.feedback') !== null) {
this.question.feedback = div.querySelector('.feedback');
this.question.feedbackHTML = true;
}
this.question.text = this.CoreDomUtilsProvider.getContentsOfElement(div, '.qtext');
if (typeof this.question.text == 'undefined') {
this.logger.warn('Aborting because of an error parsing question.', this.question.name);
return this.CoreQuestionHelperProvider.showComponentError(this.onAbort);
}
// Called by the reference in *.html to
// (afterRender)="questionRendered()
this.questionRendered = function questionRendered() {
//do stuff that needs the question rendered before it can run.
}
// Wait for the DOM to be rendered.
setTimeout(() => {
//put stuff here that will be pulled from the rendered question
});
return true;
}
};
result;
mobile/styles_app.css
This assumes you have class="qtype-YOURQTYPENAME-container in your html template. Changes will be updated when you increment the value
of styles[version] in db/mobile.php
.qtype-YOURQTYPENAME .yourclassname {
attributename: attributevalue;
}
