Quick example – skip offloading files larger than 5MB:
add_filter('advmo_should_offload_attachment', function($should_offload, $attachment_id) {
$file = get_attached_file($attachment_id);
if ($file && filesize($file) > 5 * 1024 * 1024) {
return false;
}
return $should_offload;
}, 10, 2);
Configuration
For security, cloud provider credentials are stored in your wp-config.php file rather than the database.
Note: Domain and endpoint URLs will automatically be prefixed with https:// if you don’t include it, but we recommend always including the full URL for clarity.

Using the S3 PHP SDK
The Advanced Media Offloader utilizes the AWS SDK for PHP to interact with S3-compatible cloud storage. This powerful SDK provides an easy-to-use API for managing your cloud storage operations, including file uploads, downloads, and more. The SDK is maintained by Amazon Web Services, ensuring high compatibility and performance with S3 services.
