我在php中有这个联系人表单，它具有以下功能：姓名（必需）、电子邮件（必需），电话（不必需）和消息（必需）。
原始代码：
<?php

因此，我想做一些更改，并添加更多的功能，如：姓名（必填）、电子邮件（必需）、电话（必需），地址（必需）和消息（不必需）。
然后我修改了这样的代码：

我想做的是添加一些限制，比如：必须填写姓名，如果没有，则会出现一些信息，上面写着"请写下您的姓名"；电子邮件也是如此（两者都在原始联系人表单和修改后的代码中工作）。我在手机上尝试了同样的方法（手机必须只包含数字，如果没有，就会出现一些消息，说"请写一个有效的数字"，但当我测试并写"98231176a"时，消息不会出现；地址也会出现同样的错误，显然所有信息都没有发送到管理电子邮件，因为手机无效。我对php知之甚少，如果有人能帮我的话。感谢
替换：
&& preg_match("/^[0-9]{3}-[0-9]{3}-[0-9]{3}$/", $_POST["phone"])
带有：
&& is_numeric($_POST['phone']);
以及：
|| !preg_match("/^[0-9]{3}-[0-9]{3}-[0-9]{3}$/", $_POST["phone"])
带有：
|| !is_numeric($_POST['phone']);
你也可以在functions.php中创建一个函数，并将电话号码传递给函数，然后得到true或false，以查看其有效电话号码是否如下：
function validatePhone($string) {
$numbersOnly = ereg_replace("[^0-9]", "", $string);
$numberOfDigits = strlen($numbersOnly);
if ($numberOfDigits == 7 or $numberOfDigits == 10) {
return true;
} else {
return false;
}
}
这样使用：
validatePhone($_POST['phone'])
它将解决电话号码的问题，并使其成为重要的数字，不包含任何字母
