Question

默认的WooCommerce Order Details模板的明细只显示产品名称、购买数量和总价，如果你想显示更详细的信息，或者修改显示格式，让数据更清晰，那就需要修改订单详情的模板。注意，这个修改也会影响结账后显示的“Order Received”页面。

目标

我们的目标是把图一变为图二。本文用到了文章WooCommerce Class WC_Order中提到的方法。

图一：默认的order details模板图二：修改后的order details模板

修改WooCommerce Order Details模板的方法

我们用覆盖WooCommerce模板的方法来定制，将order-details.php和order-details-item.php两个文件拷贝到主题/woocommerce/order目录下，目录不存在手动创建一下。

参考了后台界面的代码：woocommerce/includes/admin/meta-boxes/views/html-order-item.php

修改order-details.php

这个文件我们主要修改明细表单的表头，找到表头部分：

<thead>
	<tr>
		<th><?php esc_html_e( 'Product', 'woocommerce' ); ?></th>
		<th><?php esc_html_e( 'Total', 'woocommerce' ); ?></th>
	</tr>
</thead>

替换为如下代码，增加了Quantity、Cost、Tax字段。

<thead>
	<tr>
		<th><?php esc_html_e( 'Product', 'woocommerce' ); ?></th>
		<th><?php esc_html_e( 'Quantity', 'woocommerce' ); ?></th>
		<th><?php esc_html_e( 'Cost', 'woocommerce' ); ?></th>
		<th><?php esc_html_e( 'Total', 'woocommerce' ); ?></th>
		<?php
		$order_taxes = $order->get_taxes();
		if ( ! empty( $order_taxes ) ) :
			foreach ( $order_taxes as $tax_id => $tax_item ) :
				$tax_class      = wc_get_tax_class_by_tax_id( $tax_item['rate_id'] );
				$tax_class_name = isset( $classes_options[ $tax_class ] ) ? $classes_options[ $tax_class ] : __( 'Tax', 'woocommerce' );
				$column_label   = ! empty( $tax_item['label'] ) ? $tax_item['label'] : __( 'Tax', 'woocommerce' );
				/* translators: %1$s: tax item name %2$s: tax class name  */
				$column_tip = sprintf( esc_html__( '%1$s (%2$s)', 'woocommerce' ), $tax_item['name'], $tax_class_name );
				?>
				<th>
					<?php echo esc_attr( $column_label ); ?>
				</th>
				<?php
			endforeach;
		endif;
		?>
	</tr>
</thead>

修改order-details-item.php

这个文件要大改一下，代码如下。

<?php
/**
 * Order Item Details
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/order/order-details-item.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce\Templates
 * @version 5.2.0

修改成功后，就能看到图二的样子了。除了增加了额外字段，还略微修改了退款的显示方式，让退款更明显。
