Creating new asset types.

[taverin]

I am designing a portfolio that needs to show examples of MP3 files. I feel like I did all the parts, but I nothing is populating the content area.

I added app/asset-types/audio.inc.html which is:

<?php

Class Audio extends Asset {

  static $identifiers = array('mp3');

  function __construct($file_path) {
    # create and store data required for this asset
    parent::__construct($file_path);
    # create and store additional data required for this asset
    $this->set_extended_data($file_path);
  }

}

?>

I then added this to populate any audio files.

{% for audio in child.audio %}

<embed height="50" width="100" src="{{ audio.url }}">

{% endfor %}

Am I missing something here?

Hey @taverin, extending Asset is generally only useful if you need to add specific types of data to certain types of assets. It won't create custom-named collections of files for you.

You shouldn't need to add a special file type for mp3s though. For each type of file attached to a page, stacey will create a special named collection for it. So you can get a list of all mp3s attached to a page through page.mp3, in the same way, all pdfs attached to a page can be accessed though page.pdf, etc. etc.

If you really wanted to add a collection of files in page.audio, then you would need to add some code to create_asset_collections inside app/page-data.inc.php, ie.

  static function create_asset_collections($page) {
    # page.files
    $page->files = Helpers::list_files($page->file_path, '/(?<!thumb|_lge|_sml)\.(?!yml)([\w\d]+?)$/i', false);
    # page.images
    $page->images = Helpers::list_files($page->file_path, '/(?<!thumb|_lge|_sml)\.(gif|jpg|png|jpeg)$/i', false);
    # page.numbered_images
    $page->numbered_images = Helpers::list_files($page->file_path, '/^\d+[^\/]*(?<!thumb|_lge|_sml)\.(gif|jpg|png|jpeg)$/i', false);
    # page.video
    $page->video = Helpers::list_files($page->file_path, '/\.(mov|mp4|m4v)$/i', false);
    # page.audio
    $page->audio = Helpers::list_files($page->file_path, '/\.(mp3)$/i', false);

    # page.swf, page.html, page.doc, page.pdf, page.mp3, etc.
    # create a variable for each file type included within the page's folder (excluding .yml files)
    $assets = self::get_file_types($page->file_path);
    foreach($assets as $asset_type => $asset_files) {
      $page->$asset_type = $asset_files;
    }
  }
