Question

看起来正在访问send.php并发送空白电子邮件。需要这样做send.php不发送电子邮件，除非在表单上使用提交按钮。我被告知'isset $ _post'会帮助我，只是不清楚如何执行它。

这是send.php代码：

    <?php

$recipient  =   'test@test.com';

$email      =   $_REQUEST['Email'];

$subject    =   'Contact Form Submission';

$content    =   "The following has been submitted on your website \n\n";

$redirect   =   'thankyoupage.html';

$user = $_REQUEST['Email'];
$usersubject = "Subject";
$userheaders = "From: test@test.com\n";
$usermessage = "Blah blah blah";
mail($to,$subject,$message,$headers);
mail($user,$usersubject,$usermessage,$userheaders);

foreach($_POST as $k=>$v)
    {
        $content .= "$k: $v\n\n";
    }

mail_it(stripslashes($content), $subject, $email, $recipient);

if (isset($_POST['redirect']))
    {
        header("Location:".$_POST['redirect']);
    }
        else
    {
        header("Location: $redirect");
    }

function mail_it($content, $subject, $email, $recipient)
    {

        $headers .= "From: ".$email."\n";
        $headers .= "Reply-To: ".$email."\n";

        if ($bcc) $headers .= "Bcc: ".$bcc."\n"; 

        $headers .= "X-Priority: 0\n";
        $headers .= "X-Mailer: bjm Formmail \n";
        $message = $content."\n\n";

        if( !mail($recipient, $subject, $message, $headers))
        {
            echo "Sorry - an error occured trying to send the mail";
        }

    }

?>

Answer 1

您需要在标题行的末尾使用\r\n。但是如果你只有一个标题，你根本就不需要它。

Answer 2

您需要确保只有在发布请求时才会执行代码。您可以通过将所有内容包装在：

中来实现

if ($_SERVER['REQUEST_METHOD'] === 'POST')
{
   ...
}

Answer 3

如果您想发送邮件，只有当有人点击提交按钮时，只需使用此

即可

if (isset($_POST['submit'])){
   send_mail();      //and define send mail somewhere else 
}

Answer 4

您必须检查请求方法是否为POST。如果是这样，您应该发送电子邮件：

<?php

$recipient  =   'test@test.com';

$email      =   $_REQUEST['Email'];

$subject    =   'Contact Form Submission';

$content    =   "The following has been submitted on your website \n\n";

$redirect   =   'thankyoupage.html';

$user = $_REQUEST['Email'];
$usersubject = "Subject";
$userheaders = "From: test@test.com\n";
$usermessage = "Blah blah blah";


foreach($_POST as $k=>$v)
    {
        $content .= "$k: $v\n\n";
    }

if($_SERVER["REQUEST_METHOD"] == "POST") {
     mail_it(stripslashes($content), $subject, $email, $recipient);
}

if (isset($_POST['redirect']))
    {
        header("Location:".$_POST['redirect']);
    }
        else
    {
        header("Location: $redirect");
    }

function mail_it($content, $subject, $email, $recipient)
    {

        $headers .= "From: ".$email."\n";
        $headers .= "Reply-To: ".$email."\n";

        if ($bcc) $headers .= "Bcc: ".$bcc."\n"; 

        $headers .= "X-Priority: 0\n";
        $headers .= "X-Mailer: bjm Formmail \n";
        $message = $content."\n\n";

        if( !mail($recipient, $subject, $message, $headers))
        {
            echo "Sorry - an error occured trying to send the mail";
        }

    }

?>

将此添加到您的php脚本：

if ($Name == '')
{
    die("<p align='center'><font face='Arial' size='6' color='#FF0000'>Please use our<a href=''> contact form</a> to send a message to us</font></p>");
}

之后添加：

$Name = Trim(stripslashes($_POST['Name'])); 
$Email = Trim(stripslashes($_POST['Email`enter code here`'])); 
$Tel = Trim(stripslashes($_POST['Tel'])); 
$Message = Trim(stripslashes($_POST['Message']));

如果您收到空白电子邮件，则表示某人正在浏览器中运行action="contact.php"脚本，如www.yousite.com/contactsend.php

上面的代码将阻止它
