Again another Google AMP article, this time dealing with Syntax Highlighting. If you have a code centric website, this is important.
In one of my last articles I talked about a Generic Syntax Highlighter. This time I want to show you, how to add Syntax Highlighting with GeSHi to a custom template in AMP-WP.
Please read up on documentation, as I am not diving into every detail.
The AMP (Accelerated Mobile Pages Project) plugin for WordPress is still pretty young and under heavy development.
There are little things that can help to fix current validation problems. I have a couple of fresh AMP pages, that are already indexed by Google.
The currently registered Microformats template (schema.org-NewsArticle) requires an image.
The AMP-WP documentation explains how to add a featured image to your pages (documentation).
I extended that a bit, to link a default attachment image, I uploaded before. This needs to be added to your themes functions.php.
Next we adjust the Microformats definition. This needs to be added to your themes functions.php.
Read the AMP-WP documentation first :) This forces AMP-WP to override the core template with your own. Use the default template as a reference.
Normally the core sanitizer should take care of that. I am sure a filter will be added in the future. For now, this is a quick workaround. You can use a RegExp or DOMDocument to alter the amp-content in your custom template and filter things that break validation.
I am using phpQuery for now, as it allows me to add quick fixes. DOMNode or QueryPath works nicely as well :) Will be looking at the core sanitizer and options later this week. All of this is currently added to the custom template.
Finally output the fixed content as HTML.
The above examples need to be tweaked to your specific content requirements.
The custom template “post_amp_content” before:
The custom template “post_amp_content” after:
From the AMP specification :”Note, that AMP document may also be linked to directly…”
This is being added to the custom template as well.
You can find a simple pure PHP highlighter here. Not perfect, but a start. Don not forget to include the CSS :)
I will extend on this as new validation errors or tweaks come up. The core sanitizer of AMP-WP still needs some work and should allow us to do some of the above directly, when the content is parsed / converted for AMP.

Time to get AMP ready
Google’s AMP is here to save us from slow mobile content delivery, by enforcing strict standards and limiting what is allowed within AMP pages. The pages only allow a subset of tags and introduce their own tags for fast prefetching of content (images, videos … AMP Specs)
“The Accelerated Mobile Pages (“AMP”) Project is an open source initiative that came out of discussions between publishers and technology companies about the need to improve the entire mobile content ecosystem for everyone – publishers, consumer platforms, creators, and users.
Today, the expectation is that content should load super fast and be easy to explore. The reality is that content can take several seconds to load, or, because the user abandons the slow page, never fully loads at all. Accelerated Mobile Pages are web pages designed to load instantaneously – they are a step towards a better mobile web for all.”
AMP pages are cached within the AMP Cache, providing even faster delivery of your content. The core libs validate your implementation and highlight any problems by pushing errors to the console.
The documentation lists all components currently supported within a page and experimental components in development as well.
I have already added AMP support to our blog posts:
Google’s Webmaster Tools also integrates a new section for AMP, to see how they perform.
AMP is not supposed to replace your webpage, but offer a faster access point to presented content. It will not solve all use cases, but offer better performance for your simple reading pleasure for now. Its a start and lets see how it evolves ;)
Simple way to do some Visual Composer Grid cleanup, when you are using Bootstrap within your theme. This removes and cleans up classes.

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.
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.
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. 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.
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.
One solution I am currently looking at is Intuo, which is a fresh startup out of Gent / Belgium. They provide a solid set of features and a clean API to handle single signons and content access. That would allow a seamless integration into WordPress for example :)
We are looking at a very crowded LMS market, but always nice to have options :)
CodePress Admin Columns allows you to manage and organize columns, for posts, users, comments and media lists in the WordPress admin panel.
This little tweak allows you to add sorting to your columns. Add and adjust depending on the columns you have setup.
Anyone using WPLMS 1.9x should wait and not update to 2.0x yet.
Not all bugs are fixed and I see many users having problems, just by reading the support forums and the comments over on Envato.
I have a vanilla test environment of WPLMS 1.9x on my testserver and i had no problems until 2.0 came along.
The last customtypes plugin update today killed the setup completely. Many of the old child themes break or have parts broken. Fresh sample data is not working either. Sadly some of my customers already did an update themselves …. perfect ! Will be a long weekend.
I am doing a complete reset of my test environment and waiting for the next update :)
Rant: This theme / plugin is getting too bloated in many areas. Two many unknown variables, due to the huge amount of dependencies …
