Add thumbnails view in App Desk

It is actually quite simple. You need to define two special keys in data_mapping:

• thumbnail: thumbnail item path ;
• thumbnailAlternate : default path when no item thumbnail path is defined.

In the file config/common/item.config.php:

<?php

return array(
    'data_mapping' => array(
        'thumbnail' => array(
            'value' => function ($item) {
                foreach ($item->medias as $media) {
                    return $media->get_public_path_resized(64, 64);
                }
                return false;
            },
        ),
        'thumbnailAlternate' => array(
            'value' => function ($item) {
                return 'static/apps/mon_appli/icons/64.png';
            }
        ),
    ),
);

You need then to enable the thumbnails view in the App Desk configuration my_app::config/controller/admin/appdesk.config.php :

 <?php

 return array(
     'model' => '',
     'query' => array(),
     'inspectors' => array(),
     'i18n' => array(),
     'thumbnails' => true,
 );

If you want to show the thumbnails view by default:

 <?php

 return array(
     'model' => '',
     'query' => array(),
     'inspectors' => array(),
     'i18n' => array(),
     'thumbnails' => true,
     'appdesk' => array(
         'appdesk' => array(
             'defaultView' => 'thumbnails',
         ),
     ),
 );
