Trouble Posting Option Select to IPN Listener

[jakebur01]

This is more of a Paypal question, but I'm using php on the listener and hopefully someone has run into this problem.  I'm having trouble finding the correct POST name to use to get the OPTION SELECT for the item on my listener page.

I tried:

$option = $_POST['os0'];

But, I'm not getting anything using that. I've also tried os0_x, on0, and on0_x.

This is what I'm posting to Paypal:

<input type="hidden" name="on0" value="Term">
<select name="os0">
<option value="1 Year">1 Year</option>
<option value="3 Years">3 Years</option>
<option value="5 Years">5 Years</option>
</select>

Use var_dump() to see what $_POST contains:

echo "<pre>";
var_dump($_POST);
echo "</pre>";

You can find the variable you want from that.

Since I am not the one accessing the page, but Paypal, I've been trying to troubleshoot via mail().  I tried putting var_dump into my message but didn't work.

  $message = "<pre>";
$message .= var_dump($_POST);
$message .= "</pre>";
  $message = wordwrap($message, 70);

  // send email
  mail($to, $subject, $message, $headers);

Ok... I used:

// compose message
  $message = "<pre>";
$message .= print_r($_POST);
$message .= "</pre>";
  $message = wordwrap($message, 70);

  // send email
  mail($to, $subject, $message, $headers);

But, all it returned was the number 1.  "1".

I also tried:

  // compose message
  printArray($_POST);

function printArray($array){
     foreach ($array as $key => $value){
        $message .= "$key => $value<br />";
        if(is_array($value)){ //If $value is an array, print it as well!
            printArray($value);
        }
    }
}
  $message = wordwrap($message, 70);

  // send email
  mail($to, $subject, $message, $headers);

But, it was blank.

I know it is posting the custom field for sure as I have sent different values and received them back via post.
