For some digital product websites, we need to put 1 time the digital products in the cart or checkout. In this case, we can use the code below for implementing this funcitionality.
add_filter( 'woocommerce_product_tabs', 'woo_reorder_tabs', 98 );
function woo_reorder_tabs( $tabs ) {
$tabs['reviews']['priority'] = 5; // Reviews first
$tabs['description']['priority'] = 10; // Description second
$tabs['additional_information']['priority'] = 15; // Additional information third
return $tabs;
}
