Options and Meta Reference

Options (`wp_options`)

Option	Purpose
`wog_settings`	The single array holding every plugin setting
`wog_version`	Installed plugin version
`wog_migration_completed`	Flag set once legacy settings are migrated
`wog_sitemap_last_generated`	Timestamp of the last sitemap generation
`wog_flush_rewrite_rules`	Transient flag that triggers a rewrite flush after activation
`wog_rewrite_rules_flushed_v2`	Guard so the sitemap rewrite rules flush only once

All plugin settings live inside wog_settings. Add new settings to the defaults array and let wog_validated_settings sanitize them rather than creating sibling options.

Product meta

Meta keys the plugin owns:

Meta key	Purpose
`_wog_og_title`	Per-product social title override
`_wog_og_description`	Per-product social description override
`_wog_disable_og`	Set when Open Graph output is disabled for the product

Meta keys the plugin reads but does not own (used to fill gaps when present):

Brand: _brand, plus the taxonomies product_brand, pwb-brand, yith_product_brand, pa_brand
Condition: _condition
GTIN family: _gtin, _upc, _ean, _isbn, _gtin8, _gtin12, _gtin13, _gtin14
MPN: _mpn, _manufacturer_part_number
Manufacturer and model: _manufacturer, _model
Attributes: _color, _size, _material, and the pa_color, pa_size, pa_material product attributes
Image alt text: _wp_attachment_image_alt
Yoast description on the shop page: _yoast_wpseo_metadesc

Scheduled events

Event	Schedule	Purpose
`wog_generate_sitemaps`	Daily	Rebuild all sitemaps in the background
`wog_generate_single_sitemap`	One-off	Rebuild a single sitemap type or page

Both are cleared on deactivation, along with the plugin’s transients.

AJAX actions

Handled through admin-ajax.php:

Action	Access	Purpose
`wog_generate_sitemap`	Admin (`manage_woocommerce`)	Trigger a full sitemap regeneration from the settings page
`wog_test_sitemap`	Admin (`manage_woocommerce`)	Fetch and validate the sitemap index
`wog_track_share`	Public (logged in and logged out)	Report a front-end share event

The admin actions verify the wog_admin_nonce and the manage_woocommerce capability. The share tracking action verifies the wog_share_nonce.

REST API

The plugin does not register any REST API routes.
