Reply-To标题没有选择php变量

Question

I am creating a page that sends the response from contact form within mail but reply-to is not working (the variable i am using is having value, but is not added within headers)

here's my code:

<?php

//$uname=$_REQUEST['uname'];
if(isset($_REQUEST['name']))
{
    $name=$_REQUEST['name'];
}

if(isset($_REQUEST['email']))
{
    $email=$_REQUEST['email'];
}   

if(isset($_REQUEST['phone']))
{
    $phone=$_REQUEST['phone'];
}

if(isset($_REQUEST['message']))
{
    $message=$_REQUEST['message'];
}

// TESTING IF VARIABLES HAVE VALUES
echo "$name $email $phone $message";
// RESULT: TRUE TILL HERE


if($name=="" || $email=="" || $phone=="" || $message=="")
{
    header("location:../?inst=invalid");    
}
else
{

    // ---------------- SEND MAIL FORM ----------------

// send e-mail to ...
$to="[e-mail]";

// Your subject
$subject="$name Contacted you via Contact Form";

// From
$headers  = "From: ME <[e-mail]>
";
$headers .= 'Reply-To:' . $email . "
";
$headers .= "Return-Path: [e-mail]
";
$headers .= "X-Mailer: PHP
";
$headers .= 'MIME-Version: 1.0' . "
";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "
"; 

print $message;
// send email
$sentmail = mail($to,$subject,$message,$headers);
//$sentmail = mail($to1,$subject,$message,$header);
}

// if your email succesfully sent
if($sentmail){
echo "Mail Sent.";
}
else {
    header("location:../landing/?status=verification-pending");
    }

?>

Now when i checked headers in my gmail, the value for $email doesn't appear in header information, Also no message is received. All I get is a blank message or may be $message is not printing anything like the same case i am facing with reply-to.

please help me a little with this. Thanks in advance.

Answer 1

Actually there was a little mistake with the above code. I mistakenly added = instead of == while comparison.

This line:

if($name=="" || $email="" || $phone="" || $message="")

Should read as:

if($name=="" || $email=="" || $phone=="" || $message=="")

Since = is for equation and not a condition for comparison ==
