php邮件表单不发送电子邮件，并导致404错误

Question

我的php邮件表单在本地主机中正常工作（它当然不会发送任何内容，但不会显示错误）。 但是，当我上传它时，单击“提交”按钮会导致404页作为新标签页打开。 当我将其发送为空时，没有错误。 但是如果我将数据放入其中，则会出错。
这是代码：

if (isset($_REQUEST['email']))
    {
        $num = $_REQUEST['num'] ;
        $desc = $_REQUEST['desc'];
        $subject = "einak";
        $nomr = $_REQUEST['nomr'] ;
        $sphr = $_REQUEST['sphr'] ;
        $cylr = $_REQUEST['cylr'] ;
        $angr = $_REQUEST['angr'] ;
        $addr = $_REQUEST['addr'] ;
        $diar = $_REQUEST['diar'] ;
        $noml = $_REQUEST['noml'] ;
        $sphl = $_REQUEST['sphl'] ;
        $cyll = $_REQUEST['cyll'] ;
        $angl = $_REQUEST['angl'] ;
        $addl = $_REQUEST['addl'] ;
        $dial = $_REQUEST['dial'] ;
        $type = $_REQUEST['type'] ; 
        $matter = $_REQUEST['matter'] ;
        $color = $_REQUEST['color'] ;
        $message = $num .  "<br />" . $nomr . "<br/>" . $sphr . "<br/>" . $cylr . "<br/>" . $angr . "<br />" . $addr . "<br />" . $diar . "<br />" . $noml . "<br/>" . $sphl . "<br/>" . $cyll .

"<br />" . $color . "<br />";
        $email = '';
        $headers  = 'MIME-Version: 1.0' . "\r\n";
        $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
        $email= '';
        mail ( "" , $email , $message , $headers ) ;
        echo "ارسال شما موفقیت آمیز بود";
    }
else
    {
      echo "<form method='post'>

Answer 1

动作页面丢失！ 您应该在action属性内提供php页面。

<form action="yourpage.php" method="post">

Answer 2

mail命令的第一个参数是“收件人”地址。 您将其留空。 参见http://nl3.php.net/manual/en/function.mail.php
