PHP Mailer is not sending 'field input' - php

Question

Sorry folks, but I think I have a little problem (easy to solve) but I am not getting the solution by myself. Could you help me out?
The problem I am facing is this:
- the PHP script (handled by PHP mailer) is sending an e-mail, but not the information people fill in at the form.
Here is the php script I use:
<?php
$to = "user#domain.com";
$subject = "Request";
$message = "<h1>Request</h1>";
$message .= "<strong>street</strong>: $_POST['street']";
$message .= "<strong>store</strong>: $_POST['store']";
$headers = "From: request#domain.com";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html\r\n";
$sent = mail($to, $subject, $message, $headers);
if( $sent = mail($to, $subject, $message, $headers) ){ echo "SENT"; } else { echo "There
was a problem"; }
?>
Thanks in advance!

<?php
$to = "user#domain.com";
$subject = "Request";
$message = "<h1>Request</h1>";
$message .= "<strong>street</strong>:".$_POST['street'];
$message .= "<strong>store</strong>:".$_POST['store'];
$headers = "From: request#domain.com";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html\r\n";
$sent = mail($to, $subject, $message, $headers);
if( $sent = mail($to, $subject, $message, $headers) ){ echo "SENT"; } else { echo "There
was a problem"; }
?>

There were a few problems with your code.
Your headers $headers .= "MIME-Version: 1.0\r\n"; were malformed and were adding 1.0 etc. to the From: therefore resulting in 1.0 <request#domain.commime-version>
Also, your mail() function was being executed twice, therefore sending 2 emails at the same time.
I fixed your headers including your mail() by removing $sent = mail($to, $subject, $message, $headers); and modifying the if condition.
Assuming this is what you are using for an HTML form which I used to test it with:
<form method="POST" action="mail_handler.php">
<p>
<label>Street:<br>
<input name="street" type="text">
</label>
</p>
<p>
<label>Store:<br>
<input name="store" type="text">
</label>
</p>
<input name="submit" type="submit" value="Submit" />
</form>
mail_handler.php
<?php
$to = "user#domain.com";
$subject = "Request";
$message = "<h1>Request</h1>";
$message .= "<strong>street</strong>:".$_POST['street'];
$message .= "<br>";
$message .= "<strong>store</strong>:".$_POST['store'];
$headers = "MIME-Version: 1.0\n";
$headers .= "Content-Type: text/html; charset=iso-8859-1\n";
$headers .= "From: user#domain.com" . "\r\n" .
"Reply-To: user#domain.com" . "\r\n" .
'X-Mailer: PHP/' . phpversion();
if(mail($to, $subject, $message, $headers) ){
echo "SENT"; } else { echo "There was a problem"; }
?>
