(page_hook) action-hook . WP 1.5.0

Used to call the registered callback for a plugin screen.

This hook uses a dynamic hook name, (page_hook), which refers to a mixture of plugin page information including:

  1. The page type. If the plugin page is registered as a submenu page, such as for
    Settings, the page type would be 'settings'. Otherwise the type is 'toplevel'.
  2. A separator of '_page_'.
  3. The plugin basename minus the file extension.

Together, the three parts form the (page_hook). Citing the example above, the hook name used would be 'settings_page_pluginbasename'.


add_action( '(page_hook)', 'action_function_name_8991' );
function action_function_name_8991(){
	// action...


Since 1.5.0 Introduced.
