Use https://github.com/trendyminds/craft-amplify/ for compatibility with PHP 7.3.
Matt Adams's Amplify plugin ported to Craft 3 (<v2.0) and Craft 4 (>= v2.0), improved to support responsive images and iframes.
- Install with Composer via:
composer require balazscsaba2006/amplify - Navigate to
Settings -> Pluginsand click the "Install" button
The plugin uses a Twig filter to run through the AMP filter settings. To add this to your template, you will need to apply the filter like so:
{{ entry.body|amplify|raw }}
By default, this plugin will find and replace image, video, and audio tags with their Google AMP counterparts. The plugin also strips non AMP approved tags from the copy and adds layout="responsive" to amp images to enable responsive image layouts.
