Hooks and Filters

This page lists the hooks the addon provides for developers, plus the key hooks it consumes. The addon registers no REST routes, no shortcodes, no blocks, no custom post types, and no WP-CLI commands. It exposes one AJAX action.

Filters the addon fires

Profile tab labels and slugs

Filter	Args	Purpose
`reign_wcfm_favourite_product_tab_name`	`$name`	Rename the Favourite profile tab.
`reign_wcfm_favourite_product_tab_slug`	`$slug`	Change the Favourite tab URL slug.
`reign_wcfm_vendor_store_tab_name`	`$name`	Rename the Store profile tab.
`reign_wcfm_vendor_store_tab_slug`	`$slug`	Change the Store tab URL slug.

Favourite icon and product lists

Filter	Args	Purpose
`reign_wcfm_favourite_product_icon`	`$html`	Filter the full heart-icon markup before output.
`reign_wcfm_fav_product_bp_tab_posts_per_page`	`$posts_per_page`	Products per page on the Favourite and Store profile tabs.
`reign_dokan_fav_product_bp_tab_posts_per_page`	`$posts_per_page`	Legacy alias of the above, kept for back-compatibility. Prefer the `reign_wcfm_` name.

Activity action text

Filter	Args	Purpose
`reign_wcfm_format_activity_action_product_create`	`$action`, `$activity`	Filter the “added a new product” action string. Also applied at creation time with one argument.
`reign_wcfm_format_activity_action_product_review`	`$action`, `$activity`	Filter the “wrote a review” action string.
`reirn_wcfm_format_activity_action_product_create`	`$action`	Legacy misspelled alias applied at product-creation time only. Kept for back-compatibility. Use the correctly spelled filter above.

Admin and store

Filter	Args	Purpose
`wbtm_reign_wcfm_vertical_tabs`	`$tabs`	Add or change the vertical sub-tabs (General, Single Store) inside the WCFM Marketplace settings tab.
`wcfm_store_wrapper_class`	`$classes`	The addon adds the current layout class (`layout_one` / `layout_two`) to the WCFM store wrapper. It is also applied by the Layout 2 template.

Actions the addon fires

Action	Purpose
`render_theme_options_for_wcfm_general`	Renders the General sub-tab controls. Consumed by the addon itself.
`render_theme_options_for_wcfm_single_store`	Renders the Single Store sub-tab controls. Consumed by the addon itself.

AJAX action

Action	Access	Purpose
`product_mark_favuorite`	Logged-in users	Toggles a product in the current user’s favourites. Validated by the `reign-wcfm-nonce` nonce and confirmed to be a real `product` post before storing.

Note the deliberate spelling favuorite. It is a fixed contract between the JavaScript and the PHP handler. Do not rename one side without the other.
