In a perfect world all current browsers would allow the usage of WebRTC natively, but that is as always not the case ;)


„WebRTC (Web Real-Time Communication) is an API definition drafted by the World Wide Web Consortium (W3C) that supports browser-to-browser applications for voice calling, video chat, and P2P file sharing without the need of either internal or external plugins.“ – Wikipedia

I am working on a new website for a customer and we are using the WPLMS (WordPress Learning Management System) as a foundation. The packaged theme is based on Bootstrap.

The theme provides its own page-builder, but we prefer to use Visual Composer, as we built some custom VC-Addons to ease future page updates for our customer and custom content integration. Visual Composer provides some nice full-width addons, which are not working with the current theme layout. I decided to use a custom page template to allow Visual Composer to take over, where needed :) WordPress, WPLMS, Visual Composer and full width content weiterlesen


The Contact Form 7 for WordPress is a nice simple plugin to build contact forms fast. But when it comes to making it completely multilingual it lacks a bit.

I am currently creating a website with 13 different languages, that would mean to create the same contact form 13 times, not really practical :)

I am translating the form labels on the fly with some javascript magic, but for the messages I had to go a bit deeper.

  1. Open wp-content/plugins/contact-form-7/classes.php
  2. Go to line 800 function message
  3. Change this

    to this

    See how I wrapped the gettext function for the return, that does all the magic.
  4. Next we have to make sure that the messages are being found by localization helpers like Codestyling Localization
  5. In your theme functions.php add a translation for each of the Contact 7 Form messages
  6. The first message in the Contact 7 Form admin says: Your message was sent successfully. Thanks.

  7. Do not change these messages in the Contact 7 Form admin anymore or the setup will break. These updates will have to be repeated with each plugin update, unless the author does something similar.
  8. Happy translating.



WPML for WordPress is a powerful plugin to build a multi-language setup. But it still comes short in some areas, especially when it comes to a custom integration into plugins or when using custom post-types.

Normally this function should return the id of the linked translated content, but has not worked for me in some cases (especially when AJAX is involved).

A simple SELECT helps to get that id yourself :)



Bootstrap can not be added directly to the admin of a plugin, but you can wrap your plugin in a container and compile the Bootstrap CSS to use it as a wrapper.

I do my compiling using SimpLess

In the past you could do this using SimpLess directly (my-own-bootstrap.less).

This fails with the latest version of Bootstrap. But you can just paste the Bootstrap CSS into the LESS file and compile it that way.

Run it through SimpLess and after that the new CSS can be enqueued in WordPress ! This also works nicely with themes from Bootswatch.



NGFB Open Graph+ Pro is currently the best plugin around, when it comes to well integrated OpenGraph integration into WordPress.

„NGFB Open Graph+ adds Open Graph, Pinterest Rich Pins, Twitter Cards, and Search Engine Optimization HTML tags to the head section of webpages.“
