Podio PHP API, file doesn't upload, no errors

I'm trying to do something with Podio API, I'm a beginner. So my code is:

PodioItem::create($app_id, array('fields' => array(
"title" => ($name . " " . $surname),
"adres-e-mail-2" => $email,
), 
array("file_ids" => $file->id) ));

Item is created without problems, but without a file uploaded. Error log throws only deprecation:

PHP Deprecated: curl_setopt(): The usage of the @filename API for file uploading is deprecated. Please use the CURLFile class instead in /home/avat/public_html/avat/aiesec/test/podio/lib/Podio.php on line 179

File upload script is working, I can save it to my folder. I have Podio file ID working. I don't really know where to look for errors now.

Solution

It's almost always easier to work with objects rather than the static methods. As for uploading a file I've broken the example below out in sections so it's easier to see what's going on:

// Upload file
$file = PodioFile::upload("/Users/andreas/Desktop/irwin.jpg", "irwin.jpg");

// Create a new item object
$item = new PodioItem(array(
  'app' => new PodioApp(8018420),
  'fields' => new PodioItemFieldCollection()
));

// Set a value for the field with the external id 'title'
$item->fields['title'] = new PodioTextItemField();
$item->fields['title']->values = $name . " " . $surname;

// Create a new collection for files and add the $file to this collection
$item->files = new PodioCollection(array($file));

// Save the item to Podio
$item->save();
