Mailer wont work correctly

Question

I'm trying to use this mailer and have it redirect to a success/fail page depending on the fields a user enters. It works and sends the mail and also redirects to a success page when all the fields are entered, but when nothing is entered it just goes to a blank page but still sends the mail?

How could I make this work as intended? Ideally I would like it to just direct to the same page and show a success or error message within the page but I don't know how to do it.

My code for my mailer is below:

<?php
$name = $_POST['name'];
$company = $_POST['company'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$website = $_POST['website'];
$features = $_POST['features'];
$budget = $_POST['budget'];
$timeline = $_POST['timeline'];
$content = $_POST['content'];
$additional = $_POST['additional'];

$to = "[email protected]";
$subject = "Project Req: $company";
$body = "Name: $name \n\n Company Name: $company \n\n Email: $email \n\n Phone Number: $phone \n\n Website: $website \n\n Features: $features \n\n Budget: $budget \n\n Timeline: $timeline \n\n Content: $content \n\n Additional Info: $additional";
$from = $email;

if(!empty($_POST['name']) || !empty($_POST['email']) || !empty($_POST['phone']) || !empty($_POST['features']) || !empty($_POST['budget']) || !empty($_POST['timeline']) || !empty($_POST['content'])){ 

if (mail($to, $subject, $body, $headers)) {
    header("Location: success.php");
} else {
    header("Location: error.php");}
}
?>

Answer 1

You don;'t appear to have $headers set. That may be the issue, set it up so that it sends it with $headers

Answer 2

In your if statement where you check that you received everything through POST , you should use the "and" comparator && and not the "or" comparator ||. In your case, the condition will be true if only one of the POST variable is not empty - unless this is what you want?

You should also check the content of the POST variables before assigning their value to your variables at the top. You could do something like suggested by Tibbers.
