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

I am a full-stack developer. My expertise include:
I love programming, design and know my way around server architecture as well. I would never feel complete, with one of these missing.
I have a broad range of interests, that’s why I constantly dive into new technologies and expand my knowledge where ever required. Technologies are evolving fast and I enjoy using the latest.
Apart from that, I am a peace loving guy who tries to have people around him that think the same. I truly believe in the principle: “If you help someone, someone will help you, when you need it."
