我一直在寻找一种解决方案，当选择货到付款选项时，在付款选项区域的结帐页面上显示一个自定义输入字段。选择后，它会显示一个字段，客户在其中输入一个值，并将数据发送到管理订单详细信息页面。这就是我想到的。我在结帐/付款方式中插入了此代码。php

<?php if ( $gateway->has_fields() || /* $gateway->get_description() && */ $gateway->id != "cod" ) : ?>
<?php endif; ?>
<?php if ( $gateway->id == "cod" ) : ?>
<div class="payment_box payment_method_<?php echo $gateway->id; ?>" <?php if ( ! $gateway->chosen ) : ?>style="display:none;"<?php endif; ?>>
<input type="text" name=\'cod_custom_field\' placeholder="Enter Your Margin" >
</div>
<?php endif; ?>     

这是结账页面上的样子Checkout COD custom box

这里是驻留在函数中的代码。php

/** 
 * Update the order meta with field value
 */
add_action( \'woocommerce_checkout_update_order_meta\', \'my_custom_checkout_field_update_order_meta\' );

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( ! empty( $_POST[\'cod_custom_field\'] ) ) {
        update_post_meta( $order_id, \'COD Custom Field\', sanitize_text_field( $_POST[\'cod_custom_field\'] ) );
    }
}


/** Field Entry Karne ke liye
 * Display field value on the order edit page
 */
add_action( \'woocommerce_admin_order_data_after_shipping_address\', \'my_custom_checkout_field_display_admin_order_meta\', 10, 1 );

function my_custom_checkout_field_display_admin_order_meta($order){
    echo \'<p><h2><strong><h2>\'.__(\'Reseller Margin\').\':</h2></strong> \' . get_post_meta( $order->id,\'COD Custom Field\', true ) . \'</h2></p>\';
}

以下是签出页面上的图像当我输入一个值时，它在管理订单详细信息中显示如下内容：Admin Order Details

现在，我希望在前端的订单详细信息页面上也显示相同的值。PLz tell me how do I do it? 在这里，我希望输入值显示在“保证金或奖金”标签上Order details page on My account (customers)

<?php
add_action( \'woocommerce_after_checkout_billing_form\', \'display_extra_fields_after_billing_address\' , 10, 1 );
function display_extra_fields_after_billing_address () {
    _e( "Delivery Date: ", "add_extra_fields");
    ?>
    <br>
    <input type="text" name="add_delivery_date" class="add_delivery_date" placeholder="Delivery Date">
  <?php 
}

add_action( \'woocommerce_order_details_after_order_table\',
            \'namespace\\custom_field_display_cust_order_meta\', 10, 1 );

function custom_field_display_cust_order_meta( $order ) {
  echo \'[whatever]\';
  /* translators: whatever */
  echo \'<p>\' . sprintf( __( \'<strong>Property 1:</strong> %1$s (%2$s)\' ),
                        get_post_meta( $order->get_order_number(),
                                       \'property 1.1\', true ),
                        get_post_meta( $order->get_order_number(),
                                       \'property 1.2\', true ) )
       . \'</p>\';
  echo \'[whatever]\';
}
