Attachment API - save file and link to record

[murray99]

I want to create a new record with an associated attachment which is based on a file in the file system. I've been trying to find how attachments are handled for a standard upload, but I don't understand what is going on.

I want to:
a) Create new record
b) Create a new attachment record and save
c) Copy a pre-existing file to the attachments file repository
d) Set the attachment field value on the record and save

I seem to be able to to all except c). where would I find the correct method for storing a file into the file repository (default upload dir)

Attachments are somewhat difficult to understand. Here is some code I wrote that downloads an image from a url, adds the image to an attachment, and relates the attachment to another object.

  public function getAndRelateMedia($message, $data) {
    $numMedia = (int)($data->NumMedia);
    if($numMedia <= 0) return;

    for($i = 0; $i < min($numMedia, 10); $i++) {
      $typeName = "MediaContentType{$i}";
      $type = $data->$typeName;
      if(!in_array($type, array("image/gif", "image/png", "image/jpg", "image/jpeg"))) {
        continue;
      }

      $urlName = "MediaUrl{$i}";
      $url = $data->$urlName;

      $attachment = $this->em->getNewEntity('Attachment');
      $attachment->set('contents', file_get_contents($url));
      $attachment->set('name', "Media {$i}");
      $attachment->set('type', $type);
      $attachment->set('role', "Inline Attachment");
      $this->em->saveEntity($attachment);

      $this->em->getRDBRepository("MessageC")->getRelation($message, "media")->relate($attachment);
    }
  }​ 

file_get_contents can open files on your system as well, which may be what you need to use for part c.
