$tabs[‘shipping’] = array(
‘title’ => __( ‘הוראות כביסה’, ‘child-theme’ ),
‘priority’ => 10,
‘callback’ => ‘my_shipping_tab_callback’
);
return $tabs;
}

function my_shipping_tab_callback() {
// The new tab content
echo do_shortcode(‘[html_block id="6483"]‘);
}

add_filter( ‘woocommerce_product_tabs’, ‘reordered_tabs’, 98 );
