Read from S3

Hi!

I’ve been looking around the web and maybe I’m not aware of the right terms to search for, but I’ve been looking for a way to keep the Media Library in its entirety on Amazon S3. The reason is I’m hosting with Heroku/Appfog which doesn’t allow me to store the files on the web server and deletes them on every application restart.

Is this included or not? How do I set it up? I can serve the files from S3 etc, works just great. But they’re all broken in the WordPress admin.

I wrote a small plugin myself to give me the ability to do this, but it’s you know… It’s a hack right now, I’d much rather see it in the plugin! 🙂

Here’s the small plugin which gives me the stuff I need at least:

add_filter( 'wp_get_attachment_image_attributes', 's3_reads_wp_get_attachment_image_attributes' );
function s3_reads_wp_get_attachment_image_attributes($array)
{
  $array['src'] = s3_reads_replace_image_url($array['src']);
  return $array;
}

add_filter( 'wp_get_attachment_url', 's3_reads_wp_get_attachment_url' );
function s3_reads_wp_get_attachment_url($url)
{
  $url = s3_reads_replace_image_url($url);
  return $url;
}

function s3_reads_replace_image_url($url)
{
  $config = w3_instance('W3_Config');
  $bucket = $config->get_string('cdn.s3.bucket');

  $siteurl = get_site_url();

  return str_replace($siteurl, "http://{$bucket}.s3.amazonaws.com", $url);
}
