Timber / Twig templates are normally not recognized by Poedit. Its just a matter of tweaking the C/C++ extractor within the settings panel.
Add TWIG to the filetypes: *.c;*.cpp;*.h;*.hpp;*.cc;*.C;*.cxx;*.hxx;*.twig
Gettext calls, like {{__(“Points Conversion Rate”, “wplms-extras”)}} in Timber, are being extracted from your templates after that.
Easier than using the gettext extractor :)
Excel needs to know that you are using non-ASCII characters in your CSV or it will not display them correctly :)
Add the BOM(Byte Order Mark) to the first line, notifying Excel that you are offering a UTF-8 encoded file.
I am currently working on a WPLMS enhancement for a customer, that allows to simplify the payout of instructor commissions. The whole system runs on the MyCred Points System and students pay for courses with Points. The problem is how to easily payout the instructor commissions via PayPal.
There is currently no addon for MyCred available that does that magic, so I build one myself.
At the moment the payment process via PayPal is completely manual, due to budget constraints. I am basically generating a custom “Send Money” link that prefills the PayPal email and amount to send.
The interface itself handles the payout sessions, tracks the instructor balance, paid and unpaid points.
Here some images to illustrate the admin dashboard:
This list the instructors and their point balance and allows to start the payment process.
Payout sessions make sure, that only one session can be started per instructor, as the instructor could earn new points during the process. The points converted can be changed, allowing you to payout a fixed amount of points.
Its a 3 step process. Login at PayPal. Open the “Send money” dialog and send money to instructor. Confirm that you manually send the money and than register the payment and payout points in the system.
The session can be cancelled at any point. You can also leave the session open and continue at a later point.
On the frontend I added an interface to the BuddyPress Profile, that allows the instructor to track his payouts and balance.
The whole setup could be updated using PayPal Adaptive Payments, to make the whole process completely automated. Something to consider for the future :) Pretty happy with the manual process so far and it will be a great help for my customer to keep track of the commission payouts.
The whole setup is currently targeted for WPLMS, but can easily be adapted to other setups using the MyCred Points System.
Now go ahead and use $_SESSION freely in your plugin. Here a nice additional class to encrypt session data.
HyperDB is a plugin for spreading your websites load across several servers and databases. Its currently used in production on WordPress.com.
Just started experimenting with it :)

Since version 5.6+ PHP is verifying peer certificates and host names by default when using SSL/TLS. This is causing problems on some servers / websites, where the config has not been setup correctly. If you can not fix the setup yourself, make sure to talk to your server host to fix that issue.
For PHPMailer (Github) there is a workaround:
This should only be a workaround until your configuration has been fixed. You are suppressing certificate verification and compromising your security!
As WordPress is using PHPMailer as its main email library, this can be tweaked by using the phpmailer_init hook:
Add this to your themes functions.php.
And here is how phpmailer->smtpOptions should be used, on a properly configured server:

Twital is a small addon for the Twig template engine, it adds shortcuts and makes Twig’s syntax more suitable for HTML based (XML, HTML5, XHTML, SGML) templates.
Should be also no problem to integrate it with Timber, currently looking into that ;)

“Powerful database abstraction layer with many features for database schema introspection, schema management and PDO abstraction.”
The following will get you started, these offer the Doctrine\Common and Doctrine\DBAL namespaces.
In the end your structure should look something like that:
includes/ includes/doctrine includes/doctrine/lib includes/doctrine/lib/Doctrine includes/doctrine/lib/Doctrine/Common includes/doctrine/lib/Doctrine/DBAL
The following will add a class loader, so that all the other classes will be autoloaded.
This will setup your first connection to a MySQL database.
This will do a simple first query
DBAL gives us some nice options to prepare queries.
By using the bindValue the placeholder “?” is replaced. You can also use named parameters :)
More about this in the official documentation.
That was not too difficult ;)
TWIG allows you to use regular expressions within its templates, this makes it possible to easily check if a post is sticky in Timber for WordPress.

This is the template that is called within the loop on the index.twig to show each post.
The post.class holds the full set of classes assigned to a post, which includes the class “sticky”. We do the match magic and you can use that to style your sticky posts differently ;)
“Timber helps you create fully-customized WordPress themes faster with more sustainable code. With Timber, you write your HTML using the Twig Template Engine separate from your PHP files.
This cleans-up your theme code so, for example, your php file can focus on being the data/logic, while your twig file can focus 100% on the HTML and display.”
