php表单邮件(post）仍然不起作用

我正在尝试完成一个简单的表单发送，但尽管现在看起来是发送电子邮件，但没有发送任何内容。。

$name = $_POST['name']; //Sender's name
$email = $_POST['email']; //Sender's email
$message_text = $_POST['message']; //Sender's message
$phone = $_POST['phone']; //Sender's phone no
$methodOfContact = $_POST['methodOfContact']; //Sender's methodOfContact
$group1 = $_POST['group1']; //Sender's an existing customer
$other = $_POST['other']; //filler
$AppointmentType = $_POST['AppointmentType']; //Sender's AppointmentType
$WhenSuits = $_POST['WhenSuits']; //Sender's WhenSuits
$message = $_POST['message']; //Sender's message

//Declare which field naems we're already using.
$currently_active = array(  'name',
                            'email',
                            'message',
                            'phone',
                            'methodOfContact',
                            'group1',
                            'AppointmentType',
                            'WhenSuits'
                            );

//Add fields added through theme options page to Email
$custom = '';
foreach ($currently_active as $key => $currently_active) {
    if($currently_active['value']) {
        $custom.= $currently_active['name'] . ": " . $currently_active['value'] ."<br /> 'n";
    }
}

谢谢大家的帮助，我真的很感激！！！！！！！！！！！！！！！！！！
