I was trying to activate the custom stylesheet I defined for one of my Piklist add-ons. My plugin is in plugins/mcw-piklist-custom. Under that I have an add-ons directory. The only activated add-on is mcw-post-custom.

I looked at the way Piklist Demos does it and found the following function:

  add_filter('piklist_assets', 'piklist_demo_assets');
  function piklist_demo_assets($assets)
  {
    array_push($assets['styles'], array(
      'handle' => 'piklist-demos'
      ,'src' => piklist::$addons['piklist']['url'] . '/add-ons/piklist-demos/parts/css/piklist-demo.css'
      ,'media' => 'screen, projection'
      ,'enqueue' => true
      ,'admin' => true
    ));

    return $assets;
  }

I found it curious the way it’s using the piklist::$addons array to pick up the URL. Looked at that array, and here’s what I saw:

Array
(
    [piklist] => Array
        (
            [path] => /Users/donna/Sites/marys/wp-content/plugins/piklist
            [url] => http://marys.dev/wp-content/plugins/piklist
        )

    [theme] => Array
        (
            [path] => /Users/donna/Sites/marys/wp-content/themes/marysriver/piklist
            [url] => http://marys.dev/wp-content/themes/marysriver/piklist
        )

    [mcw-piklist-custom] => Array
        (
            [path] => /Users/donna/Sites/marys/wp-content/plugins/mcw-piklist-custom
            [url] => http://marys.dev/wp-content/plugins/mcw-piklist-custom
        )

    [wp-helpers] => Array
        (
            [path] => /Users/donna/Sites/marys/wp-content/plugins/wp-helpers
            [url] => http://marys.dev/wp-content/plugins/wp-helpers
        )

    [piklist-demos] => Array
        (
            [path] => /Users/donna/Sites/marys/wp-content/plugins/piklist/add-ons/piklist-demos
            [url] => http://marys.dev/wp-content/plugins/add-ons
        )

    [mcw-post-custom] => Array
        (
            [path] => /Users/donna/Sites/marys/wp-content/plugins/mcw-piklist-custom/add-ons/mcw-post-custom
            [url] => http://marys.dev/wp-content/plugins/add-ons
        )

)

I have two thoughts:

1. I am uncomfortable accessing a class variable like this; would rather call a function to return a value. (data hiding) E.g., piklist::add_on_data( 'mcw-post-custom', 'url' )

2. I’m curious as to why the add-on URLs do not have the correct path. E.g., for piklist-demos it should be http://marys.dev/wp-content/plugins/piklist/add-ons/piklist-demos.

Thanks,
Donna
