下訂單前驗證WooCommerce電話號碼

Question

我正在嘗試以921234456格式轉換客戶的電話號碼。

這是我放入functions.php中的代碼

// Format phone number in this format: 923131234567
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
    global $woocommerce;

  /**
     *Format phone number in this format: 923131234567
     * If no country code is provided, by default 92 (Pakistan) country code is added.
     * @param $phone
     * @return string
     */
    $phone = $_POST['billing_phone']

    function formatPhoneNumber($phone]) {
        $phone = trim($phone);
        $phone = str_replace([' ','-','_'],'',$phone);
        if(empty($phone)) {
            return NULL;
        }

        $phone = ltrim(ltrim($phone, '0'),'+');
        if(strlen($phone) <= 11) {
            $phone = '92' . ltrim($phone,0);
        }

        return $phone;
    }
}

使用此代碼，我認為它將正常工作。 謝謝

function formatPhoneNumber($phone) {
    $phone = trim($phone);
    $phone = str_replace([' ','-','_'],'',$phone);
    if(empty($phone)) {
        return NULL;
    }

    $phone = ltrim(ltrim($phone, '0'),'+');
    if(strlen($phone) < 11) {
        $phone = '92' . ltrim($phone);
    }

    return $phone;
}
}
