Your problem is that you’re working with an Array in PHP.

echo $visitRecord->getReferallist(); // Returns array of referrals.

When you cast the array to a string by echo’ing it (because echo outputs strings) then you get the text “Array”.

In order to send this over the wire(from javascript via AJAX ($.post)) you will need to convert your referral list into a string. One method is serialization. You can convert your array into a “stringable format” using the serialize() function. http://www.php.net/serialize.

When this is received from PHP in the AJAX request you can convert your “stringable formatted” array back into a pure array using the unserialize() function. http://www.php.net/unserialize.

Your code should change from

$visitRecord->getReferallist();

to

serialize($visitRecord->getReferallist());

Then when it’s received you should change your code from

$referrals = $_POST[‘referalList’]; // Stringable version of the array

to

$referrals = unserialize($_POST[‘referalList’]); // Pure PHP array
