    }
  ]
];

More control over the uploaded file

In the action state, you get access to the uploaded file. The file is a (toolkit: media) object, with tons of features to check for the size, dimensions, mime types and even exif data if that is of any use.

<?php

// site/roles/editor.php
return [
  'name'        => 'Editor',
  'default'     => false,
  'permissions' => [
    '*'                    => true,
    'panel.avatar.upload' => function() {

      if($this->state() === 'ui') {
        // always show the upload button
        return true;
      }     

      // but check if the uploaded file is square
      if($this->target()->upload()->isSquare() === false) {
        return 'The source image really should be square!';
      } 

      return true;

    }
  ]
];
