Add filter hook to change or override weight
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
applyfilters( 'epomscalculatedoptionweightshipstation', wcgetweight( $product->getweight(), 'oz' ), $product, $item, 'oz' )
