HTML/PHP 联系表 - 电话号码未接通

Question

预先感谢您的帮助。

在 HTML/CSS/JS 网站上，我正在使主题提供的联系表单工作正常，但我似乎无法让电话号码字段工作。我已经尝试过不使用 sanitize、更改 id，似乎没有任何效果。

HTML：

 <section class="contact-page">
            <div class="container">
                <div class="section-title text-center">
                    <div class="section-title__icon">
                        <img src="assets/images/icon/section-title-icon.png" alt="">
                    </div>
                    <span class="section-title__tagline">Contact with us now</span>
                    <h2 class="section-title__title">Feel free to write gardon <br> anytime</h2>
                </div>
                <div class="contact-page__form-box">

如果有人能指出我正确的方向，那就太好了。

提前致谢。

已尝试更改 HTML 和 PHP 文件中的 ID 和名称。还尝试删除 sanitize，并尝试将访问者电话添加到名称框中，由于某种原因，PHP 文件无法从 HTML 文档中获取它。

无论我如何获得它，电子邮件都会很好地提取其他数据，而电话号码仍然是空的。

在代码部分：

if(isset($_POST['visitor_phone'])) {
    $concerned_department = filter_var($_POST['visitor_phone'], FILTER_SANITIZE_NUMBER_INT);
    $email_body .= "<div><label><b>Phone Number:</b></label>&nbsp;<span>".$visitor_phone."</span></div>";
}

Ypou 将电话号码信息分配给“$concerned_department”，但随后打印出“$visitor_phone”。

顺便说一句，出于多种原因，您绝对不想将电话号码清理为整数。它可能以零开头，有时人们会输入空格，在某些国家/地区他们会输入标点符号......
