Hey @leodm,

This is a requirement for the WordPress server.

Good luck with getting this setup and let me know how you get on 🙂

If you have any other questions feel free to get in contact 🙂

Thanks,

Tom

Haven’t heard back from you for a while so I’m going to assume this is not required.

If not, don’t hesitate to get back in contact and we’ll see what we can do 🙂

Thanks,

Hey @jamasi,

for someone who is not into wordpress code that much the documentation could be a little more verbose.

You’re right that the documentation is aimed at people who already know and use WordPress. It’s always a balance of getting the right level of detail but I will take on your feedback.

Also info on where to put his hook would be needed as putting custom code into the functions.php of the theme seems to be discouraged in general.

Functions.php is an ok place to put code. Unless you want to learn more WordPress I would encourage it. If you want to Google it, my personal belief is that best practice in most situations like this would be to create a custom plugin and add this to the mu-plugins directory so that it is code that does not need to be activated (and can’t be deactivated) in the admin area. How far you want to go in your learning is your call.

I appreciate this is daunting but how these things work is not in the scope of this plugin. There are many forums and guides out there to teach these basics. Alternatively, there are plenty of developers who would happily take on the paid work if you need support beyond what the plugin is doing.

I think your code will not work, as the salt is coming from another column of the DB table and thus it is per user.

As I think you later realised I added a line that should do what you want to achieve.
$user_specific_salt = $externalUserData[$db_data["dbstructure_salt"]];
Make sure however you you set the field mapping in the External Login settings for the salt field.

After digging into the source of wordpress, I suppose, [your code]
should work. Still I wonder what settings to use in the configuration page to activate it.

Any code you put in functions.php will run with every request to the site, including when someone tries to login and the plugin is used.

Sorry to be a nuisance, but how can I debug if the hook is installed? So far I get correct looking data from the connection test, but I cannot login with any user.

You can add error_logs in php to output data. The tricky thing is finding exactly where they will output to on your setup. You will have to investigate this yourself as there are so many variables that will be factor.

To help make sure you have some logs showing I would recommend adding the following lines to the top of your functions.php file. If you can see these logs, you can then start adding similar lines elsewhere to check values and see if the code reached certain points:

error_log(var_export('EXLOG START!!!!', true));
$someTestData = 'quick test';
error_log(var_export($someTestData, true));
error_log(var_export('EXLOG END!!!!', true));

I would expect to see the following three outputs in your PHP error logs:

EXLOG START!!!!
quick test
EXLOG END!!!!

I hope all of this helps,

Tom

The following line tells us the plugin is running. It is only a warning (that I’m aware of) but will not break anything.

PHP message: PHP Notice:  Undefined index: exlog_authenticated in /var/www/community/wp-content/plugins/external-login/login/authenticate.php on line 30

The following line is probably an issue because it is throwing an error.
2020/04/18 16:19:33 [error] 27699#27699: *5903 FastCGI sent in stderr: "PHP message: PHP Warning: pg_query(): No PostgreSQL link opened yet in /var/www/community/wp-content/pg4wp/driver_pgsql.php on line 139

This is not to do with the plugin as far as I’m aware as it is in /var/www/community/wp-content/pg4wp/driver_pgsql.php.

The fact that you didn’t see any of the other logs I suggested you add makes me thing that the plugin failed to authenticate the user but the hook may not be running.

Add an addition error_log at the start of your functions.php file and see if you can see that in these logs when you log in.

You could also add another one at the start of the plugin file if that is showing.

Let me know how you get on 🙂
