WP_Customize_Manager::post_value( WP_Customize_Setting $setting, mixed $default = null )

Returns the sanitized value for a given setting from the current customized state.


The name "post_value" is a carry-over from when the customized state was exclusively sourced from $_POST['customized']. Nevertheless, the value returned will come from the current changeset post and from the incoming post data.
