PHP联系表格空白电子邮件

Question

Looks like send.php is being accessed and sending blank emails. Need to make it so send.php doesn't send email, unless the submit button is used on a form. I was told 'isset $_post' would help me, just not clear on how to execute it.

Here's send.php code:

    <?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

add this to your php script:

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>");
}

add it just after:

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

if you are getting blank emails it means someone is running the action="contact.php" script from the browser like www.yousite.com/contactsend.php

this code above will stop it

Answer 2

You need to use \\r\\n at the end of header lines. But if you only have one header you don't need it at all.

Answer 3

You need to make sure the code is only executed when there is a post request. You can do that by wrapping everything in:

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

Answer 4

If you want to send mail, only when someone hits submit button, simply use this

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

Answer 5

You have to check wether the request method was POST. If so, you should send the email:

<?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";
        }

    }

?>

This makes it all happen:

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