must return the 'templates', the 'javascript', and 'otherdata' with the data required for the javascript and template.

e.g.

        $otherdata = ['usefulstuff' => json_encode($usefulstuff)

        , 'maxsize' => $maxsize

        , 'filetypes' => '.png,.jpg,.jpeg,.pdf,.doc,.docx,.bmp,.odt', 'attachments' => ""

];

        return [

            'templates' => [

                [

                    'id' => 'main',

                    'html' => $OUTPUT->render_from_template('myplugin/template_name', $data),

                ],

            ],

            'javascript' => file_get_contents($CFG->dirroot . "myplugin_path/mobile/template_javascript.js"),

            'otherdata' => $otherdata

        ];

2 template part 1: the attachments selector

myplugin/template_name
This creates the functionality to select and gather the documents into the mobile app.

<core-attachments [files]="CONTENT_OTHERDATA.attachments"

[maxSize]="CONTENT_OTHERDATA.maxsize"

[maxSubmissions]="1"

    [component]="myplugin"

[acceptedTypes]="CONTENT_OTHERDATA.filetypes"

[allowOffline]=false>

 </core-attachments>

3 template part 2

myplugin/template_name
We now need to let the user agree to send these documents.

<ion-button (click)="updateContent(CONTENT_OTHERDATA)" color="primary" expand="block" name="myplugin_upload" successMessage="{{ 'plugin.myplugin.done' | translate }}" refreshOnSuccess="true">

          Send

</ion-button>

4 javascript for the button

myplugin_path/mobile/template_javascript.js

this.updateContent = function(allinfo) {

    let attachments = allinfo.attachments;

    if ((!attachments.length) {

        return false;

    }

    return this.saveFiles(allinfo);

};

this.saveFiles = async function (inputData) {

    let saveOffline = false;

    let response;

    const modal = await this.CoreDomUtilsProvider.showModalLoading('core.sending', true);

    // Upload attachments.

    try {

        let attachmentsId; // number | undefined;

        attachmentsId = await this.uploadOrStoreSubmissionFiles(inputData.attachments, false);

        const params = {

            attachments: attachmentsId,

        };

        const site = await this.CoreSitesProvider.getSite();

        response = await site.write('myplugin_add_attachments', params);

        if (response.status === true) {

            this.CoreDomUtilsProvider.showToast(

                this.TranslateService.instant('plugin.myplugin.uploadsuccessful'), true, 6000);

        } else {

            this.CoreDomUtilsProvider.showToast(

                this.TranslateService.instant('plugin.myplugin.uploadfailure'), true, 6000);

        }

    } catch (error) {

        this.CoreDomUtilsProvider.showErrorModalDefault(error, 'Cannot save files');

    } finally {

        modal.dismiss();

        this.CoreFileUploaderProvider.clearTmpFiles(inputData.attachments);

        this.CONTENT_OTHERDATA.attachments = [];

    }

    return response;

};

6 Classes\External.php

public static function add_attachments

The file gets uploaded into user draft files. So to access, make 

        $fs = get_file_storage();

        $file = $fs->get_area_files($contextid, 'user', 'draft', $attachments

            , "itemid, filepath, filename", false, 0, 0, 0);

        $uploadStatus = true;

        foreach ($file as $f) {

            $filecontent = $f->get_content();

            $filename = $f->get_filename();

            $encoded = base64_encode($filecontent);

            // Do stuff with file

        }

        $fs->delete_area_files($contextid, 'user', 'draft', $attachments);
