開發時遇到的一個很奇怪的需求，但想想這需求也很合情合理，在 Woocommerce 的會員後台中，其實有這個欄位編輯，是在收件地址資料那邊設定的，既然處理了就順便筆記分享下來
很可能以後都是標配（？）
首先要進到你的佈景主題中，找到 functions.php 記得備份一下，接著新增以下程式碼
//會員資料編輯新增手機
add_action( 'woocommerce_edit_account_form', 'add_billing_mobile_phone_to_edit_account_form' );
function add_billing_mobile_phone_to_edit_account_form() {
$user = wp_get_current_user();
?>
<p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
<label for="billing_mobile_phone"><?php _e( '手機號碼驗證（再輸入一次）', 'woocommerce' ); ?> <span class="required">*</span></label>
<input type="text" class="woocommerce-Input woocommerce-Input--phone input-text" name="billing_mobile_phone" id="billing_mobile_phone" value="<?php echo esc_attr( $user->billing_mobile_phone ); ?>" />
</p>
<?php
}
// 檢查驗證電話欄位
add_action( 'woocommerce_save_account_details_errors','billing_mobile_phone_field_validation', 20, 1 );
function billing_mobile_phone_field_validation( $args ){
if ( isset($_POST['billing_mobile_phone']) && empty($_POST['billing_mobile_phone']) )
$args->add( 'error', __( '手機號碼有所不同，請檢查下方確認再次填寫', 'woocommerce' ),'');
}
// 儲存電話號碼欄位進會員資料
add_action( 'woocommerce_save_account_details', 'my_account_saving_billing_mobile_phone', 20, 1 );
function my_account_saving_billing_mobile_phone( $user_id ) {
if( isset($_POST['billing_mobile_phone']) && ! empty($_POST['billing_mobile_phone']) )
update_user_meta( $user_id, 'billing_mobile_phone', sanitize_text_field($_POST['billing_mobile_phone']) );
}上面完成之後，請進到 Woocommerce 外掛資料夾內，找到 templates/myaccount/form-edit-account.php 先COPY一個備份，再打開編輯
<p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
<label for="billing_mobile_phone"><?php _e( '手機號碼', 'woocommerce' ); ?> <span class="required">*</span></label>
<input type="text" class="woocommerce-Input woocommerce-Input--phone input-text" name="billing_mobile_phone" id="billing_mobile_phone" value="<?php echo esc_attr( $user->billing_mobile_phone ); ?>" />
</p>找到你要的位置，把這個欄位 HTML 安插進去
他插入位置自己去判斷，我是插入在 Email 後面，會像以下這樣：
<?php
/**
* Edit account form
*
* This template can be overridden by copying it to yourtheme/woocommerce/myaccount/form-edit-account.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 WooCommerceTemplates
* @version 3.5.0
