Hide original subtotal line from WooComerce admin order totals

Question

These post is related with Add a custom total line to WooCommerce admin order totals

Hello

I'm trying to hide Subtotal, but I can not find the class in CSS like:

.cart-subtotal  { display: none; }
.order-total { display: none;    }
.order_shipping_line_items {display: none;}

It doesnt work.

Now I'm trying to unset with these code, but it doesn't work too:

add_filter( 'woocommerce_get_order_item_totals', 'reordering_order_item_totals', 10, 3 );
function reordering_order_item_totals( $total_rows, $order, $tax_display ){
    $shipping = $total_rows['line_subtotal'];
    $order_total = $total_rows['order_total'];

    unset($total_rows['line_subtotal']);
    unset($total_rows['order_total']);


    return $total_rows;
}

I try to reorder the fields and hide fields in the order of request.

Answer 1

To hide original subtotal line From admin order total lines, use the following:

add_action('admin_head', 'admin_head_shop_order_inline_css' );
function admin_head_shop_order_inline_css() {
    global $pagenow, $typenow;

    // Targeting WooCommerce admin single orders
    if ( in_array( $pagenow, ['post.php', 'post-new.php'] ) && $typenow === 'shop_order' ) :
    ?><style>table.wc-order-totals tr:first-child{display:none;}</style><?php
    endif;
}

Code goes in functions.php file of your child theme (or in a plugin). Tested and works.

Note: As all Admin Order total lines HTML are hard-coded in this file, you can not reorder them.

To hide "Envio" shipping total line too, replace the code with:

add_action('admin_head', 'admin_head_shop_order_inline_css' );
function admin_head_shop_order_inline_css() {
    global $pagenow, $typenow;

    // Targeting WooCommerce admin single orders
    if ( in_array( $pagenow, ['post.php', 'post-new.php'] ) && $typenow === 'shop_order' ) :
    ?><style>
    table.wc-order-totals tr:first-child,
    table.wc-order-totals tr:nth-child(4){display:none;}
    </style><?php
    endif;
}

Code goes in functions.php file of your child theme (or in a plugin). Tested and works.
