Using a different storage location for some attachments by using a hook

[bandtank]

In my environment, most files are stored in AWS S3. However, I want exported files from report lists to be stored locally. Using the following code, the user can choose a different storage location for certain types of attachments.

File: custom/Espo/Custom/Hooks/Attachment/AttachmentHook.php

<?php

namespace Espo\Custom\Hooks\Attachment;

use Espo\Core\Exceptions\Error;
use Espo\Core\Utils\Config;
use Espo\ORM\Entity;

use DateTime;

class AttachmentHook
{
  public function __construct(
    private Config $config
  ) { }

  public function beforeSave(Entity $entity, array $options): void {
    if($entity->get("relatedType") == "Report") {
      $entity->set("storage", $this->config->get("StorageForReportAttachments", "EspoUploadDir"));
    }
  }
}​

The attachment entity has a few fields you can use to make decisions about where to store files. For my use case, I want all files related to reports to be stored locally instead of in AWS S3. To add flexibility, a new configuration parameter called StorageForReportAttachments is exposed, which can be set in data/config.php if desired.
