FedEx Shipping Method for WooCommerce

As per our client’s requirement, we needed a way to modify the weight of the product when shipping request is processed. We needed a way to add or override the product weight with a custom field value from WooCommerce Extra Product Options. To achieve this we have added a custom filter hook in Shipping plugin where it’s retrieving the Product weight.

The following filter is added to the plugin

apply_filters( ‘epoms_calculated_option_weight_for_shipping’, wc_get_weight( $values[‘data’]->get_weight(), ‘lbs’ ), $values, ‘lbs’ )
