我是一个完整的PHP新手，这个文件是我做过的第二个PHP。基本上，我在网上找到了一个联系表单教程，我想确保它在我从测试域中删除之前是安全的，添加正确的电子邮件并使其生效。
正如我发现的那样，第84行中的某些内容并不正确，但我一点都不知道我需要修理它是什么。 任何帮助将不胜感激！
编辑 - 我正在通过Bootstrap构建我的网站，如果这对任何事情都有任何影响。
<?php
if ($_POST["submit"]) {
$InputName = $_POST['InputName'];
$InputEmail = $_POST['InputEmail'];
$InputSubject = $_POST['InputSubject'];
$InputMessage = $_POST['InputMessage'];
$InputReal = intval($_POST['InputReal']);
$from = 'Contact Form';
$to = 'test@email.com';
$subject = $InputSubject;
$body = "From: $InputName\n E-Mail: $InputEmail\n Message:\n $InputMessage";
}
if (!$_POST['InputName']) {
$errName = 'Please enter your name';
}
if (!$_POST['InputEmail'] || !filter_var($_POST['InputEmail'], FILTER_VALIDATE_EMAIL)) {
$errEmail = 'Please enter a valid email address';
}
if (!$_POST['InputSubject']) {
$errSubject = 'Please enter a subject.';
}
if (!$_POST['InputMessage']) {
$errMessage = 'Your message is empty!';
}
if ($InputReal !== 7) {
$errHuman = 'Your anti-spam is incorrect';
}
if (!$errName && !$errEmail && !$errMessage && !$errHuman) {
if (mail ($to, $subject, $body, $from)) {
$result=' <div class="alert alert-success">

} else {
$result=' <div class="alert alert-danger">
<strong>
<span class="glyphicon glyphicon-send"></span> A problem occured. Please try again shortly.
</strong>
</div> ';
}
}
