我有一个名为send_form_email.php的文件，我正试图让它向我发送一封带有trues/falses或某种表示选中了哪些复选框的电子邮件。我认为我试图扩展我在互联网上发现的东西的方式有问题——现在它可以发送表格，但没有任何关于检查了哪些项目的信息。
这些是我的网络表单上的复选框：
$farmscale = $_POST['farmscale']; // not required
$nutrients = $_POST['nutrients']; // not required
$smallscale = $_POST['smallscale']; // not required
$plantdesign = $_POST['plantdesign']; // not required
$industrialscale = $_POST['industrialscale']; // not required
$engineering = $_POST['engineering']; // not required
$stgs = $_POST['stgs']; // not required
$compsupply = $_POST['compsupply']; // not required
但这是主文件，我只是不知道如何在它发送的电子邮件中得到一个真实/虚假的值。请温柔。。。对这个东西还是有点陌生。

我通过插入一个隐藏的新输入来解决这个问题：
<input type="hidden" name="farmscale" value="n" />
<input type="checkbox" name="farmscale" value="y" />
您可以对每个复选框或单选按钮执行此操作。
为了调试的目的，如果您发送一个带有名为"checkme"的HTML复选框的表单，您可以使用var_dump（$_POST）查看是否有"checkme"项，然后可以使用isset（）函数对其进行测试。
form.html
<html>
<head>
<title>Test form</title>
</head>
<body>
<form method="post" action="see-it.php">
<input type="checkbox" name="checkme" value="test"> Check it or not... <br>
<button type="submit">Send</button>
</form>
</body>
</html>
参见-it.php
<?php
if(isset($_POST['checkme'])) {
echo "CHECKED!!!1!1 :D";
} else {
echo "Not checked... :(";
}
?>
