I am currently building a custom slides / template builder for a project, with a lot of moving parts and dynamic logic.
As there are repeating patterns within the slides, each pattern and its logic needs to be neatly separated. As the slides can be reordered and dropzones can be changed, I need to make sure logic doesn’t break and IDs get updated.
Before reassembling all templates, I am making sure that IDs match the slide and dropzone using a preg_replace_callback
One of the patterns is a simple tab setup, each has its unique ID defined like vl-tab_U1_S1_D1.
The function below passes the found matches through to the anonymous callback function in preg_replace_callback and offers outside data to the function using use($foo). The $dropzone object holds the current unit, slide and dropzone of the pattern, which can be used to replace the current ID with the correct one.

$dropzone->region_content = preg_replace_callback('/vl-tab_[^"]++/',function($hit) use($dropzone){ $oldID = explode("_",$hit[0]); $newID = array( "vl-tab", "U".$oldID[1], "S".$dropzone->slide, "D".$dropzone->dropzone ); return implode("_", $newID); },$dropzone->region_content); |
Really nice combo to make magic happen 😉

Some options to get those translatable strings out of your templates. I will be adding new things, as I discover them 🙂

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 🙂

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.

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 😉

<ul t:if="users"> <li t:for="user in users"> {{ user.name }} </li> </ul> // shorter than : {% if users %} <ul> {% for user in users %} <li> {{ user.name }} </li> {% endfor %} </ul> {% endif %} |

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.
|
1 2 |
{% if findme matches '/^[\\d\\.]+$/' %} {% endif %} |
This is the template that is called within the loop on the index.twig to show each post.
|
1 2 3 4 5 6 |
{% extends "tease.twig" %} {% block content %} <div class="{% if post.class matches '/sticky/' %}col-md-12{% else %}col-md-6{% endif %}"> <!--Your content --> </div> {% endblock %} |
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.”
Twig is a modern template engine for PHP
