Webservice: List issued certificates

[michallohnisky]

Resolves #419 .

Use-case example:
An external application (CRM) periodically downloads new certificates and associates them with users using their email addresses. The timecreatedfrom filter is used to download certificates issued after the last synchronization.

Hi,

There are a few things that need addressed.

1. The complaints from the GitHub Actions report.
2. I support Moodle 4.1 upwards so we should be using type hints, return types etc.
3. This does not resolve Call list of certificates for a user via API #419 as that specifies getting certificates for a user, not from a date.
4. Indentation of SQL should be as https://moodledev.io/general/development/policies/codingstyle/sql.
5. There are no checks to see if the user can actually get the list of certificates meaning anyone can get a list of certificates which is a huge security issue.

Please address these and I will take another look.

Hi, thanks. I will try my best :-) .

1. Almost done. They disappeared after my push. Can you run them again?
2. Can you give me an example? Because for example \mod_customcert\external::list_issues_parameters has a return type in annotations, so it is the same as \mod_customcert\external::delete_issue_parameters
3. Done. I added additional filters.
4. I cannot see what is wrong, can you give me an example?
5. Done. I added mod/customcert:viewallcertificates

1. Done.

Thanks @michallohnisky. Are you able to add some unit tests to this as well? Take a look at https://github.com/mdjnelson/moodle-mod_customcert/blob/MOODLE_404_STABLE/tests/external_test.php to see other examples. :)

Regarding the points -

2. These web services were created ages ago before type hinting and return types were a thing in PHP.
3. The SQL indentation was corrected so it's fine now.

Cheers.

P.S Once all done please squash into one commit.

[michallohnisky]

Are you able to grant me permission to run the checks? If I am able to run them immediately after every push, I think I can add some unit tests as well.

[mdjnelson]

You can run the unit tests locally before pushing them. :) https://docs.moodle.org/dev/Writing_PHPUnit_tests

I understand :-) , but I would need to set up the whole development stage and Docker containers, and it would take a lot of time for a single unit test.

I squashed the commits.

[mdjnelson]

I run the unit tests on my machine and I do not use Docker for Moodle development as I find the Moodle HQ container to be extremely slow. So, its possible to do this without Docker.
