Drupal 7 - create node programatically, adding a youtube embed to a field - php

Question

I'm trying to create nodes programatically. Using Media module with the youtube extension, I'd like to populate a field with youtube data. From what I've read so far, it's going to look something like this:
<?php
// $value in this case is the youtube ID.
$file = new stdClass();
$file->uid = 1;
$file->filename = $value;
$file->uri = 'youtube://v/' . $value;
$file->filemime = 'video/youtube';
$file->type = 'video';
$file->status = 1;
$youtube = file_save($file);
node->field_youtube[$node->language]['0']['fid'] = (array) $youtube->fid;
?>
I learned this by looking at the information in the $content variable in the bartik theme. However, this results in a "Bad file extension" error. I also tried putting the whole url in $file->uri and using file_get_mimetype on it, then it didn't throw an error but the video didn't work either. Does anyone know how to do this?

Answer 1

I found the answer. The function file_save only checks if a file id is already in the database. However, the youtube uri field did not allow duplicates. Therefore I stole this function from the file_example module. It checks if a file exists with that uri, if it does it loads the object.
function file_example_get_managed_file($uri) {
$fid = db_query('SELECT fid FROM {file_managed} WHERE uri = :uri', array(':uri' => $uri))->fetchField();
if (!empty($fid)) {
$file_object = file_load($fid);
return $file_object;
}
return FALSE;
}
So in the end I simply put an if statement, like this:
$file_exists = wthm_get_managed_file('youtube://v/' . $value);
if (!$file_exists) {
$file_path = drupal_realpath('youtube://v/' . $value);
$file = new stdClass();
$file->uid = 1;
$file->filename = $value;
$file->uri = 'youtube://v/' . $value;
$file->filemime = file_get_mimetype($file_path);
$file->type = 'video';
$file->status = 1;
$file_exists = file_save($file);
}
$node->field_youtube[$node->language]['0'] = (array) $file_exists;
This solved most problems. I still get a message saying bad file extension, but it works anyway.

I got it working like this. I'm importing embed codes that need to be parsed and some are dupes, and i think this function file_uri_to_object($code, $use_existing = TRUE) allows you to reuse managed urls.
$r->video is an iframe embed code for youtube which gets parsed to the correct uri format
// include the media youtube handler.inc file to use the embed code parsing
$path = drupal_get_path('module','media_youtube').'/includes/MediaInternetYouTubeHandler.inc';
require_once($path);
$code = MediaInternetYouTubeHandler::parse($r->video);
$youtube = file_uri_to_object($code, $use_existing = TRUE);
$youtube->display = 1;
$youtube = file_save($youtube);
$node->field_video[$lang][0] = (array)$youtube;
node_save($node);

A nicer way:
module_load_include('inc', 'media_youtube', 'includes/MediaInternetYouTubeHandler.inc');
$obj = new MediaInternetYouTubeHandler($url);
$file = $obj->getFileObject();
$file->display = 1;
file_save($file);
$product->field_product_video[LANGUAGE_NONE][] = (array) $file;
