移除/隱藏 WooCommerce 結帳頁欄位資料

若希望 WooCommerce 結帳頁時，不要出現那麼多欄位要訪客填寫，不仿利用下面的程式碼，將帳單地址 & 運送地址的欄位隱藏起來。 使用方式很簡單，只要在 WordPress 後臺，在外觀 > 佈景主題檔案編輯器 > 下拉選擇 functions.php 檔案 > 點擊選取：

<?php
// Add custom Theme Functions here

在上述文字下方插入以下程式碼即可。

add_filter( 'woocommerce_checkout_fields' , 'custom_remove_woo_checkout_fields' );
 
function custom_remove_woo_checkout_fields( $fields ) {

    // 移除帳單地址欄位
    unset($fields['billing']['billing_first_name']);
    unset($fields['billing']['billing_last_name']);
    unset($fields['billing']['billing_company']);
    unset($fields['billing']['billing_address_1']);
    unset($fields['billing']['billing_address_2']);
    unset($fields['billing']['billing_city']);
    unset($fields['billing']['billing_postcode']);
    unset($fields['billing']['billing_country']);
    unset($fields['billing']['billing_state']);
    unset($fields['billing']['billing_phone']);
    unset($fields['billing']['billing_email']);
   
    // 移除運送地址欄位 
    unset($fields['shipping']['shipping_first_name']);    
    unset($fields['shipping']['shipping_last_name']);  
    unset($fields['shipping']['shipping_company']);
    unset($fields['shipping']['shipping_address_1']);
    unset($fields['shipping']['shipping_address_2']);
    unset($fields['shipping']['shipping_city']);
    unset($fields['shipping']['shipping_postcode']);
    unset($fields['shipping']['shipping_country']);
    unset($fields['shipping']['shipping_state']);
    
    // 移除備註欄
    unset($fields['order']['order_comments']);
    
    return $fields;}
