Run calculate_shipping() on usermeta value update

  • I am working on a custom WooCommerce buildout for a client. It uses a custom shipping method plugin that calculates shipping costs based on API return values. Additionally, every customer has a piece of usermeta called freight_inclusive. If they have this enabled, shipping costs should zero out, but the cost of each item will slightly increase. This setting is toggle-able in the user admin panels.

    Toggling this changes the prices of each product correctly, BUT the shipping costs are not zeroed out until something in the cart is changed. That is, the shipping plugin is correctly responding to the usermeta value, but it doesn’t seem to run calculate_shipping() until the cart changes somehow (even hitting the ‘Update Cart’ button doesn’t work if nothing in the cart has changed). Instead, I want to trigger cart total recalculation whenever the usermeta value is updated, as below:

    add_action( 'edit_user_profile_update', 'save_freight_inclusive_toggle_field' );
function save_freight_inclusive_toggle_field( $user_id ) {

	if ( !current_user_can( 'edit_user', $user_id ) )
		return false;

	update_user_meta( absint( $user_id ), 'freight_inclusive', wp_kses_post( $_POST['freight_inclusive'] ) );

        //something like: WC()->cart->calculate_totals();
        //or: WC_Shipping_Method->calculate_costs();
}

    If I run the commented-out line, I get a 500 error. What is the proper way to instruct WooComm to re-calculate cart totals – or more specifically, to re-run the calculate_shipping() function from my custom shipping plugin – in this case?

    I’m not sure I see the use case for this. Wouldn’t a customer already have the ‘freight_inclusive’ usermeta when they are going through the checkout? Do you plan to manually add this value when customer’s are checking at?

    If a customer is checking out on your site with their computer, and you save the usermeta value to their account on your computer – it isn’t going to be easy to target their specific cart instance and update it.

    If there is something the user does that gets ‘freight_inclusive’ added to their account programmatically, then use that action to also re-run the cart calculations.
