Binding Moodle and LabNbook accounts
In `mod/labnbook/`, the page `user-binding.php` tries to bind
a Moodle account with a LabNbook account.
If the binds succeeds, the user will be redirected to the Moodle page
that requested the bind.

If the M user binds to an existing L account, Moodle won't receive the user token directly.
This token will be receined from L after the final redirection, when Moodle checks for authentication.
With the other cases, Moodle receives the user token before the final redirection,
so the user token is stored in the session, and the check for authentication
will not send a request to the L API.

Texts should be inserted with `get_string(<stringid>, "labnbook")` so that translations are possible.
The string IDs are mapped to strings through the file `lang/en/labnbook.php`.
See [Strings API]( (sic) for l10n.
### Upgrading
The process is the standard Moodle plugin process,
see <> for a tutorial.
If the DB structure is modified, you must modify the XML structure *and*
write the PHP migration.
If necessary, update the DB structure *for new installs* in `db/install.xml`.
Editing the XML is possible, but the recommended way is to use the
[web interface in Moodle](
Then modify `db/upgrade.php` to apply the changes to plugins already installed.

## Upgrade
Like any Moodle plugin:
1. update the source code in `mod/labnbook/`
2. apply the migration,
through CLI with `php admin/cli/upgrade.php`,
or through web by connecting as as an admin on the "Administration" page.
