Kirby Webmentions Plugin

This is my own spin on Bastian Allgeiers Kirby plugin for sending and receiving webmentions with your Kirby site. It might have functionality you don't need, or miss functionality you want, but it does what I need it to do.

Deprecated: I am working on a new plugin, from scratch, which takes work. Feel free to use this one in the mean time, but it's not the most user friendly and it might not always work.


Download the plugin and upload it to your Kirby site under /site/plugins/. Rename the folder to webmentions. The file webmentions.php should then be located at /site/plugins/webmentions/webmentions.php

To enable webmentions in a template, you can use the webmentions() helper:

<?php echo webmentions() ?>

Additionally you have to specify your new webmention endpoint in the header of your site:

<link rel="webmention" href="<?php echo url('webmention') ?>">

Your site is now able to send and receive webmentions.

Added options

The plugin calls the 'webmentions.new' hook when a new webmention is received. I use it to log webmentions to a separate file, to keep track of them. You can even mail yourself. Just be sure not to break the endpoint.

kirby()->hook('webmentions.new', function($mention, $src, $target) {
  // do stuff!
  // $mention is an array
  // $src and $target are strings of urls

The content of $mention comes from indieweb/php-comments.

$mention = array(
  'type' => 'reply',
  'author' => array(
    'name' => 'Aaron Parecki',
    'photo' => 'http://aaronparecki.com/images/aaronpk.png',
    'url' => 'http://aaronparecki.com/'
  'published' => '2014-02-16T18:48:17-0800',
  'name' => 'Example Note',
  'text' => 'this text is displayed as the comment',
  'url' => 'http://aaronparecki.com/post/1'

The original plugin only looks at the 'text' field of a post. You can now add new fields to monitor for urls to mention. Note that the plugin only sends mentions on the first time the page is visited. (You can remove the pings.json-file from the .webmentions-folder in that page's folder and visit the page again to resend webmentions.)

c::set('webmentions.fields', ['text', 'like_of', 'repost_of', 'in_reply_to']);

I didn't like the reverse display order, so now it's an option. false is oldest first, true is newest first.

c::set('webmentions.reverse-order', false);

Other improvements:

  • uses the router to search for pages
  • passes 20 of 21 Endpoint Discovery Tests on Webmention.rocks (not test 13 unfortunately)
  • when receiving webmentions, also checks the source page for (comma separated) urls in the 'syndication' field. So: if a webmention is received and a syndicated copy is mentioned, it still counts as a valid mention.
  • bugfixes (and probably new bugs created! :D feel free to file issues)
