ACF Revisions

Bridge hooks that save ACF Flexible Content field values and reference keys into WordPress post revisions, enabling recovery after accidental data loss.

The Problem

ACF Flexible Content fields store data using dynamic post meta keys:

WordPress core revisions (even 6.4+) cannot track these dynamic keys. When ACF field groups are accidentally corrupted or meta keys are deleted during maintenance, all flexible content data becomes unrecoverable — even though the values still exist in the database.

The Solution

This plugin hooks into WordPress's revision system to copy ACF Flexible Content meta keys to/from revision posts:

• On revision creation (_wp_put_post_revision) — copies all sections_% and _sections_% meta
• On revision restore (wp_restore_post_revision) — restores all meta and clears ACF cache
• On field group import (acf/import_field_group) — snapshots the current state for recovery

Features

• Automatic — No configuration needed. Works on every save and revision restore.
• Integrity Check — Detect orphaned meta keys and missing reference keys via WP-CLI or admin UI.
• Import Safety — Automatic snapshots before acf/import_field_group() modifications.
• Clean — Only affects sections_% and _sections_% meta keys. No custom tables.

Requirements

• WordPress 6.4+
• ACF Pro 6.0+
• PHP 7.4+
