function hook_subscriptions_digest_alter in Subscriptions 7

Same name and namespace in other branches
  1. 6 docs/docs.php \hook_subscriptions_digest_alter()
  2. 2.0.x subscriptions.api.php \hook_subscriptions_digest_alter()

This alter hook is called immediately before sending of a digest.

You get the digest bodies as well as the prepared mailvars just before they are merged into a digest, and you can do with them whatever you like. At the very extreme, you can remove digest items or even set $digest_data to NULL to suppress sending this digest.
