How can I get more than a variable from a $_POST?

Question

In the purchase button of PayPal, there is an input hidden called custom. I can add on him a variable to get it after.

The thing is, I want to get 2 variables.

Actually, I have in the value of the input this: <php? echo $customform ?> <php? echo $customform ?>

And on listener.php (this receive the post data from paypal) i have got PHPmailer working with the custom variable.

like this: $mail->Body = $_POST['custom'];

So, Paypal only gives one custom field and i want to send something like this:

$customform $loginid

and then work with both variables. How can i do it guys? thank you so much.

You can serialize the variable's value into JSON and pass the data, once you get back the json from PayPal just unserialize it.

// get the user from database
$loggedInUser = 1;

$data = json_encode(array (
  'customForm' => $_POST['key'],
  'loginId' => $loggedInUser,
));

// {"customForm": "data1", "loginId": "1"}

and whey you get back the result just decode it back to an array.

$result = json_decode ($_POST['custom'], true);

I hope that helps.
