Simple way to do some Visual Composer Grid cleanup, when you are using Bootstrap within your theme. This removes and cleans up classes.

$JSON = json_encode($OBJECT); |
Even DateTime is nicely encoded :)

Depending from where you want to access the page, post or custom post-type data, it might not always be available that easily.
WordPress provides an option to get your data through the page-slug.
The function is called get_page_by_path.

$page = get_page_by_path( basename ( $_SERVER['REQUEST_URI']),OBJECT, "your-post-type" ); |
As I said before, Learning Management is really taking off and I get many client requests to do some kind of integration or custom solution for them.
What is a LMS?
A Learning Management System (LMS) is a software application for the administration, documentation, tracking, reporting, and delivery of educational courses, training programs, or learning and development programs.
It is used by organizations to manage and deliver their internal training programs and can be used by schools and universities for managing online courses as well. An LMS typically includes features such as creating and delivering content, user management, tracking progress, assessments, reporting, and collaboration tools.
In one of my latest articles I started listing solutions for WordPress, WordPress and the LMS universe.
But those solutions might not always be the best fit for your project. Many of them actually try too hard to be everything. The amount of cross linked functionality is getting insane and increases the point of failure.
In some cases a trimmed down solid solution might be the better way to go. SaaS (Software as a Service), part of the cloud trend, is providing more and more options, this includes the LMS arena.
A SaaS solution refers to software that is delivered to users over the internet, typically on a subscription basis. Instead of installing and running the software locally on individual computers or servers, users access it through a web browser or a thin client. The service provider manages the infrastructure, maintenance, and upgrades of the software, allowing users to benefit from the latest features and improvements without having to manage the underlying technology themselves.
Stop worrying about the software and concentrate on your content again. The SaaS provider takes care of functionality, support, updates and delivery.
This is nothing new, solutions like TalentLMS or Litmos LMS offer this for some time now.
TalentLMS is a cloud-based Learning Management System (LMS) designed for small to mid-sized businesses and organizations. It offers features such as creating and delivering online courses, tracking progress and performance, reporting, and integrations with other tools like Google Drive, Dropbox, and Zapier. TalentLMS also includes mobile learning capabilities, allowing users to access courses on their smartphones or tablets. The platform is easy to use and offers a range of customization options for branding and layout. It also includes features for creating and managing certificates and badges for learners upon completion of courses.
Litmos is a cloud-based Learning Management System (LMS) designed for businesses and organizations of all sizes. It offers features such as creating and delivering online courses, tracking progress and performance, reporting, and integrations with other tools like Salesforce, Marketo, and Google Drive. Litmos also includes mobile learning capabilities, allowing users to access courses on their smartphones or tablets. The platform is easy to use and offers a range of customization options for branding and layout. It also includes features for creating and managing certificates and badges for learners upon completion of courses. Additionally, Litmos offers features for automating course assignments, tracking compliance with regulatory requirements, and providing personalized learning experiences for individual learners based on their performance and progress.
Modern SaaS solutions provide Public APIs, that allow you to seamlessly integrate them with your current solution. So in case of a LMS, that part of your project could be handled by the SaaS provider, while e-commerce, social and other content areas remain under your full control.
We are looking at a very crowded LMS market, but always nice to have options :)
Now that Parse is phasing out (01/2017), people are looking for alternatives that offer:

In the past 2 years, the e-Learning market has been exploding. Online Learning Management Systems (LMS) have become very popular, to build e-learning platforms.
They not only offer text based content, quizzes, assignment management, course evaluation, social features, but also allow the integration of video, audio and other linked content. Many support SCORM (Sharable Content Object Reference Model), allowing the exchange of learning content and results.
Over the past few years, I have been helping clients to build or transform their e-learning platforms. Sometimes its better to build a customized LMS solution from scratch :), than tweak or customize an offered solution. It all depends on the features you want to see integrated and on the budget available ;)
In this article I want to share current solutions offered for WordPress.
I will divide them into themes and plugins for now. In the future I plan do some feature comparison as well :
These are standalone plugins, that provide LMS functionality and integrate into your WordPress themes. Ease of integration and options differ.
These themes mostly dependent on one of the plugins above or offer only a simple subset of LMS functionality.
Integrated solutions, that are supposed to offer a tight integration of WordPress, theme and its own plugins.
IoT is the current buzz word and I will be doing some more tinkering with current solutions this year. I have done projects with Arduino , Raspberry Pi and looking into relayr / Wunderbar right now.
relayr provides a tech stack with Wunderbar, that easily connects included sensors with the cloud. They provide a wide range of API endpoints to collect data and even integrate hardware solutions like Arduino orRaspberry Pi.
“The WunderBar is built for software developers. It is a powerful rapid prototyping and product development tool that enables developers to immediately start creating products and solutions that utilise the Internet of Things, without any prior hardware knowledge. No soldering or electronic engineering experience is needed. Just choose what sensors you need for your project and start coding.”
Starterkit should arrive next week …
CSS Crush is a standards inspired CSS pre-processor that is written in PHP from scratch.
For a current project I am adding CSS Crush side by side to Sass. Lets see which of them sticks around in the end :) Might be keeping them both, as CSS Crush provides some nice options.
“Hybridauth enables developers to easily build social applications and tools to engage websites visitors and customers on a social level by implementing social sign-in, social sharing, users profiles, friends list, activities stream, status updates and more.
The main goal of Hybridauth is to act as an abstract API between your application and various social apis and identities providers such as Facebook, Twitter and Google.”
Hybridauth 2.x was the best option for nicely aggregated social logins so far, but some of the social “Providers” are outdated or no longer working. Version 3.0 is still in development, but providing a complete rewrite.

For Facebook , Twitter and Google+ I still use my own little wrappers, but if you want more this is the way to go in the future :)
