如何在 WooCommerce 注册页面添加确认密码字段？

我正在尝试添加代码

<?php
// Add the code below to your theme's functions.php file to add a confirm password field on the register form under My Accounts.
add_filter('woocommerce_registration_errors', 'registration_errors_validation', 10,3);
function registration_errors_validation($reg_errors, $sanitized_user_login, $user_email) {
    global $woocommerce;
    extract( $_POST );
    if ( strcmp( $password, $password2 ) !== 0 ) {
        return new WP_Error( 'registration-error', __( 'Passwords do not match.', 'woocommerce' ) );
    }
    return $reg_errors;
}
add_action( 'woocommerce_register_form', 'wc_register_form_password_repeat' );
function wc_register_form_password_repeat() {
    ?>
    <p class="form-row form-row-wide">
        <label for="reg_password2"><?php _e( 'Password Repeat', 'woocommerce' ); ?> <span class="required">*</span></label>
        <input type="password" class="input-text" name="password2" id="reg_password2" value="<?php if ( ! empty( $_POST['password2'] ) ) echo esc_attr( $_POST['password2'] ); ?>" />
    </p>
    <?php
}
?>

在 function.php 上但不起作用...任何关于如何在 woocommerce/my account/from-login.php 上添加密码确认字段的内容

作为后续约翰的回答 https://stackoverflow.com/a/39079966/7311767:

挂钩到woocommerce_checkout_init不再适用于 Woocommerce 3.x，因为他们引入了一个神奇的吸气剂，只会返回原始的$checkout->checkout_fields['account']场，无account2。我不知道这是一个功能还是一个错误。

对于 Woocommerce 3.x，正确的方法是使用过滤器。验证保持不变。

// Add a second password field to the checkout page in WC 3.x.
add_filter( 'woocommerce_checkout_fields', 'wc_add_confirm_password_checkout', 10, 1 );
function wc_add_confirm_password_checkout( $checkout_fields ) {
    if ( get_option( 'woocommerce_registration_generate_password' ) == 'no' ) {
        $checkout_fields['account']['account_password2'] = array(
                'type'              => 'password',
                'label'             => __( 'Confirm password', 'woocommerce' ),
                'required'          => true,
                'placeholder'       => _x( 'Confirm Password', 'placeholder', 'woocommerce' )
        );
    }

    return $checkout_fields;
}

// Check the password and confirm password fields match before allow checkout to proceed.
add_action( 'woocommerce_after_checkout_validation', 'wc_check_confirm_password_matches_checkout', 10, 2 );
function wc_check_confirm_password_matches_checkout( $posted ) {
    $checkout = WC()->checkout;
    if ( ! is_user_logged_in() && ( $checkout->must_create_account || ! empty( $posted['createaccount'] ) ) ) {
        if ( strcmp( $posted['account_password'], $posted['account_password2'] ) !== 0 ) {
            wc_add_notice( __( 'Passwords do not match.', 'woocommerce' ), 'error' );
        }
    }
}
