Thanks for your response. I tested out the functionality you suggested and Elgg is still returning a ElggObject instead of a ElggFile.... :/

This throws an error:

Argument 1 passed to elgg_get_download_url() must be an instance of ElggFile, instance of ElggObject given

code:

Yeah, I also had that issue.

Here's the thing, if you are dealing with files, as far as I know, you cannot use another subtype because elgg will not recognized as a file.

If you see at my code, in the elgg_get_entities() I am filtering my files with an specific category. So in my action, I keep the file subtype, but I add a category:

$file = new ElggFile();

$file->title = $file->getFilename();

$file->subtype = "file";

$file->category = "featured";

Then when I want to get the files I need, I just add the category:

elgg_get_entities(array( 'type' => 'object', 'subtype' => 'file', 'category' => 'featured')

You can view how I do my action here:

@gwcoleman Extend ElggFile using your own Class.

Example:

namespace MyPlugin;

use ElggFile;

class MotionData extends ElggFile {

    const SUBTYPE = 'motion_data';

    public function initializeAttributes() {
      parent::initializeAttributes();
      $this->attributes['subtype'] = self::SUBTYPE;
    }


   public function getDisplayName() {
      $name = parent::getDisplayName();
      
      if (!$name) {
        $name = elgg_echo('untitled');
     }

     return $name;
   }

}

Have a look at the data_Views plugin. It provides the xml output for the webservices https://github.com/Elgg/data_views

Thanks Jerome! I am going to check it out.

Now I got it to work. What I did was adding mod/my_plugin/views/xml/page/default.php file in addition to my existing code. Below is the code I copied from data_views plugin and put it in default.php file.

header('Content-Type: text/xml');

echo "<?xml version='1.0' encoding='UTF-8' ?>\n";

echo $vars['body'];

Thanks again Jerome!

You don't add the "code" for the composer install method to any file. The code you are referring to are the comands you enter at the command line to download/update the Elgg installation. See http://learn.elgg.org/en/stable/intro/install.html#overview and http://learn.elgg.org/en/stable/admin/composer.html for more info.

If in doubt, install Elgg with the traditional zip archive method.
