为什么我在表单发送后返回php文件不起作用？

Question

    <?php
// Check for empty fields
if(empty($_POST['name'])      ||
   empty($_POST['phone'])     ||
   empty($_POST['email'])     ||
   !filter_var($_POST['email'],FILTER_VALIDATE_EMAIL))
   {
   echo "No arguments Provided!";
   return false;
   }

$name = strip_tags(htmlspecialchars($_POST['name']));
$phone = strip_tags(htmlspecialchars($_POST['phone']));
$email_address = strip_tags(htmlspecialchars($_POST['email']));

// Create the email and send the message
$to = '[e-mail]'; // Add your email address inbetween the '' replacing [e-mail] - This is where the form will send a message to.
$email_subject = "Website Contact Form:  $name";
$email_body = "You have received a new message from your website contact form.

"."Here are the details:

Name: $name

Email: $email_address

Phone: $phone
";
$headers = "From: [e-mail]
"; // This is the email address the generated message will be from. We recommend using something like [e-mail].
$headers .= "Reply-To: $email_address";   
mail($to,$email_subject,$email_body,$headers);
return readfile(polychor_file.pdf);         
?>

I have a response and all work correct with status 200, so why did I cannot take my file back? I need to show pdf file after the form sent.

Answer 1

You need to change the Header:

header("Content-type: application/pdf");
header("Content-Disposition: inline; filename=filename.pdf");
@readfile('path\to\filename.pdf');
