<input id="msg" name="coment" type="text" placeholder="Comments..." style="height:50px;"/>
<input class="submit" type="submit" value="" onclick="return validateForm()"/>
</form>

process.php：

$name = $_POST["name"];
$email = $_POST["email"];
$address = $_POST["address"];
$zipcode = $_POST["zipcode"];
$state   = isset($_POST["state"]);
$coment = $_POST["coment"];

/* This takes the information and lines it up the way you want it to be sent in the email. */

$subject = ' Contact From '.$name; // Subject for the email
        $body = "Name: $name <br />";
        $body .= "Email: $email <br />";
        $body .= "Address: $address <br />";
        $body .= "State: $state <br />";
        $body .= "Zipcode: $zipcode <br />";
        $body .= "Msg: $coment <br />";
        $headers = 'Content-type: text/html; charset=iso-8859-1'  . "<br />";
        $sucess = mail($site_owners_email, $subject, $body, $headers);
$url = '../thank-you.html';
echo '<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">';
?>

我得到的所有其他值都很好，但状态始终是邮件中的值1为什么是这个？就像一个布尔值？感谢

Answer 1

$state   = isset($_POST["state"]);

将返回一个布尔值。这就是你获得1的原因。

你应该这样做：

 $state   = $_POST["state"];

Answer 2

这是因为你有

$state = isset($_POST["state"]);

将其更改为

$state = $_POST["state"];

第一个是返回一个布尔值，因为它会检查该变量是否已设置。

Answer 3

在状态中你放置了isset（$ _ POST [＆＃34; state＆＃34;]）这是一个布尔值你看到的1意味着真实你必须写：

$state   = $_POST["state"];

选择选项的值
