You can use values from other Plugin Republic plugins in your Product Add-Ons Ultimate field formulas. This guide lists the parameters available for Bulk Variations and Bookings for WooCommerce.
Add a parameter to a calculation field’s ‘Formula’ box in the same way as any other field placeholder. The plugin replaces it with the matching value when the customer makes their selections.
Which parameters work with Bulk Variations?
If you’re using the grid layout in Bulk Variations, you can get the total number of variations the customer has selected with this parameter:
{total_variations}For example, {total_variations} * 5 adds a charge of 5 for each variation selected.
Which parameters work with Bookings for WooCommerce?
There are three parameters for Bookings for WooCommerce:
{calculated_booking_cost}: returns the total cost of the selected booking.{num_units_int}: returns the number of units selected, such as days or weeks.{num_bookings}: returns the quantity selected.
For example, {calculated_booking_cost} * 0.1 returns 10% of the booking cost, which you could use for an insurance add-on. Or {num_units_int} * 15 charges 15 for each day of a hire, such as a daily equipment fee.
