I am currently trying to implement what should be a simple task and send a message to one and / or more users via Moodle. In the process I found 2 guides, which confused me at first. Messaging 2.0 and Message API. Both have some differences and I didn't understand if my plugin needs to register as a Message Producer or not.
Unfortunately, I just can't get my message to be sent. I logged in with the user and checked the mailbox, no message there. Any help is appreciated.
What I did: Created message.php within my db - folder and inserted the following code:
<?php
defined('MOODLE_INTERNAL') || die();
$messageproviders = array (
'datenotification' => array (
)
);
After that I expanded my language file with this:
$string['messageprovider:datenotification'] = 'Reminder for a presentation';
Like the guide advised, I updated my plugin to insert my messageprovider in the table mdl_message_providers. Finally, I implemented the actual sending of the message.
$eventdata = new \core\message\message();
$eventdata->component = 'local_reminder'; // the component sending the message. Along with name this must exist in the table message_providers
$eventdata->name = 'datenotification'; // type of message from that module (as module defines it). Along with component this must exist in the table message_providers
$eventdata->userfrom = core_user::get_noreply_user(); // user object , no-reply
$eventdata->userto = $user; // user object from database
$eventdata->subject = 'Test message';
$eventdata->fullmessage = 'This is my test message';
$eventdata->fullmessageformat = FORMAT_PLAIN; // text format
$eventdata->fullmessagehtml = '<p>This is my test message</p>';
$eventdata->smallmessage = '';
$eventdata->courseid = $course_id; // This is required in recent versions, use it from 3.2 on https://tracker.moodle.org/browse/MDL-47162
$result = message_send($eventdata);
Debugging:
var_dump($eventdata); //-> All data is included
var_dump($result); // returns int(5), id of message, no error
