我是PHP的新手，我真的不知道我做错了什么，或者即使我做了什么是正确的，但它似乎有效，但只有下拉菜单不能完全正常工作。
$ SelectThree和$ SelectFour仅显示最后一个选择...例如，如果您选择DropDown选项A和B ...只有B将显示在电子邮件中...即：
Name: name
Number: number
Date: 10/06/2014
Select: DropdownA
Select2: DropdownA
Select3: Drop Down Option B
Select4: Drop Down Option B
Radio: female
Checkbox: OptionB
Switch: On
Email: example@example.com
Message: message
PHP：
<?php
session_start();
if ($_SERVER['REQUEST_METHOD'] == 'POST'){
ob_start();
if(isset(
$_REQUEST['name'],
$_REQUEST['email'],
$_REQUEST['message'],
$_REQUEST['number'],
$_REQUEST['date'],
$_REQUEST['select'],
$_REQUEST['selectTwo'],
$_REQUEST['selectThree'],
$_REQUEST['selectFour'],
$_REQUEST['radio'],
$_REQUEST['checkbox'],
$_REQUEST['switch'],
$_REQUEST['token'] )){
if($_SESSION['token'] != $_POST['token']){ $response = "0";
} else {
$_SESSION['token'] = "";
$name = $_REQUEST['name'];
$email = $_REQUEST['email'];
$message = $_REQUEST['message'];
$number = $_REQUEST['number'];
$date = $_REQUEST['date'];
$select = $_REQUEST['select'];
$selectTwo = $_REQUEST['selectTwo'];
$selectThree = $_REQUEST['selectThree'];
$selectFour = $_REQUEST['selectFour'];
$radio = $_REQUEST['radio'];
$checkbox = $_REQUEST['checkbox'];
$switch = $_REQUEST['switch'];
switch (true){
case !filter_var($email, FILTER_VALIDATE_EMAIL):
$response = "<p style='color:red'>Invalid Email Address!</p>";
break;

$message = "Name: $name <br/>

Select3: $selectThree <br/>
Select4: $selectFour <br/>
Radio: $radio <br/>

Message: $message";
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=utf-8' . "\r\n";
$headers .= 'From: '."support@loaidesign.co.uk" . "\r\n";
$headers .= 'Reply-To: '.$email . "\r\n";

}
break;
}
echo $response;
}
} else {
echo "Error";
}
ob_flush();
die();
}

答案 0 :(得分：3)
要使其有效，您应该在HTML中指定name="selectFour"而不是name="selectFour[]"
编辑：PHP方面，您可以利用$ _REQUEST [＆＃39; selectFour＆＃39;]作为数组。
编辑：也许，您可以使用内爆函数http://php.net/manual/en/function.implode.php
