Which option rows are affected

PolyFields manages autoload on three categories of option rows. Understanding which rows are affected helps you interpret database state after import or migration.

PolyFields stores always saved with autoload = off when field values are written (save, import, migration). The ACF options page autoload setting is not applied to per-language stores. This avoids loading every language’s field rows into alloptions on every request.

Import legacy unsuffixed source ids from each ACF options page (for example options_headline, _options_headline, and sub-keys for repeaters or groups). Autoload is disabled while the plugin is active.

Migration legacy language-suffixed ids from ACF Options for Polylang (for example options_fr_FR_headline). Autoload is disabled while the plugin is active.

See Legacy options autoload for the overview and Autoload snapshot and revert for when autoload changes are applied automatically.
