WCEmailPostsCleanup::was_never_customized │ private static │ WC 1.0

Decide whether a stored email post was never customized by a merchant.

True when any of the following independent signals holds:

  • the content matches the canonical core render recomputed right now;
  • the content still matches the sync source hash stamped at creation or backfill time (untouched even though core moved on — deleting is equivalent to what the auto-applier would do, just cheaper);
  • no valid source hash exists (email not covered by the sync registry) and the GMT creation/modification timestamps show no edit ever happened.

The stored _wc_email_template_status meta is deliberately not trusted on its own — it can be stale (sweeps only run after upgrades) or absent.

Method of the class: WCEmailPostsCleanup{}

No Hooks.

Returns

bool. True when the post can safely fall back to the file template.

$result = WCEmailPostsCleanup::was_never_customized( $post, $email ): bool;
$post(WP_Post) (required)
