php - 为什么我的链接没有通过 php 电子邮件功能显示出来？

Question

我正在尝试发送通知电子邮件(工作正常)但是添加了 html header 以尝试发送链接等...由于某种原因根本没有显示任何内容，只是应该是所需链接的空白区域成为。这是我的代码:

if(isset($_POST['commentBlogSubmit']) && $auth) {

    $query = "SELECT `Email` FROM `Users` WHERE `id` = '" . $prof->id . "'";
    $request = mysql_query($query,$connection) or die(mysql_error());
    $result = mysql_fetch_array($request); 

    $Email = $result['Email'];


    $to = $Email;
    $subject = "Someone sent you left you a comment";
    $message = "You have a new blog comment  <br />".
               " <a href='http:www.blah.org/indexNew.php'></a>";
    $from = "info@blah.org";
    $headers  = 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
    $headers .= "From: $from";
    mail($to, $subject, $message, $headers);

}

可能是因为链接标签内没有文字？
