Important note #

  • When adding either a new tax scheme, category or reason, only key/value pairs with keys that don’t conflict with existing defaults will be allowed. This means that if a provided key already exists, it will be ignored.


Example: Add tax scheme #

add_filter( 'wpo_wcpdf_ubl_tax_schemes', 'wpo_wcpdf_add_tax_scheme', 10, 1 );
function wpo_wcpdf_add_tax_scheme( $tax_schemes ) {
	$tax_schemes['EV1']  = __( 'Tax EV1', 'woocommerce-pdf-invoices-packing-slips' );
	return $tax_schemes;
}

Example: Add tax category #

add_filter( 'wpo_wcpdf_ubl_tax_categories', 'wpo_wcpdf_add_tax_category', 10, 1 );
function wpo_wcpdf_add_tax_category( $tax_categories ) {
	$tax_categories['AB'] = __( 'AB tax category', 'woocommerce-pdf-invoices-packing-slips' );
	return $tax_categories;
}

Example: Add tax reason #

add_filter( 'wpo_wcpdf_ubl_tax_reasons', 'wpo_wcpdf_add_tax_reason', 10, 1 );
