如何通过php发送带有多个select的联系人表单

我正在尝试使用Ajax和PHP发送一个PHP联系人表单。在表单中，有一个select，它接受多个选项。我从联系人表单中得到的结果在收到的电子邮件中只打印了1个值

这就是我的代码的样子

HTML

首选卧室类型
一居室
两居室
三居室
四居室

我还通过ajax.serialize（）发送了这个

PHP

通过以下代码更新您的
foreach

foreach ($_POST as $key => $value) {
    if (isset($fields[$key])) {
        switch($key){
            case 'room' :
                $emailText .= "$fields[$key]: ".  @implode(', ', $value)."\n";
                break;
            default : 
                $emailText .= "$fields[$key]: $value\n";
        }        
    }
}

$\u POST['room']
的值是一个数组。如果
$value
是使用的数组，则可以使用获取所有值

非常感谢大家！非常感谢你的帮助！
