I'm trying to calculate 30% of the total shipping cost of a purchase on woocomerce in a fixed table, but I'm not getting it via the table because the fee percent doesn't work.

is there any code that does this in php?

Try this as a plugin.

he added but added as a new field with the 30% and not in the shipping field
