Saya tidak bisa meng update data ke database

Langsung ke topik pembahasan.... saya ingin membuat UPDATE status dari web <a href=' wobbly-panel.com '> wobbly-panel.com </a> ke web saya 4propanel.com, disini saya menggunakan APIKEY dari WOBBLY - PANEL untuk mengoper ke web saya... ini contoh APIKEYnya <a href=' https://wobbly-panel.com/api_status.txt '> https://wobbly-panel.com/api_status.txt </a> dan contoh kodingan saya di bawah ini

<?php
require_once("include/config.php");
$i=0;
$tampil = mysql_query("SELECT * FROM order_history WHERE provider = 'WP'");

while($data = mysql_fetch_array($tampil))
 {
 $i++;
$saldo = $data['price'];
$no = $data['order_id'];
$buyer= $data['buyer'];

//CEK ORDERAN
if($key = "dLtL0bO6KuF7gT2Gr6Zb"){ // your api key
$order_id = "$no"; // your order id
$postdata = "key=$key&action=status&order_id=$order_id";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://wobbly-panel.com/api.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$chresult = curl_exec($ch);
curl_close($ch);
$json_result = json_decode($chresult, true);


if($status == 'Pending'){
      $scmd = 'Pending';
      $update = "update order_history set status = '$scmd' where order_id = '$no'";
                $exe = mysql_query($update);
   } else if($status == 'Completed'){
      $scmd = 'Completed';
      $update = "update order_history set status = '$scmd' where order_id = '$no'";
                $exe = mysql_query($update);
   } else if($status == 'Partial'){
      $scmd = 'Partial';
      $update = "update order_history set status = '$scmd' where order_id = '$no'";
                $exe = mysql_query($update);
   } else if($status == 'Canceled'){
            $scmd = 'Canceled';
      $update = "update order_history set status = '$scmd' where order_id = '$no'";
      $exe = mysql_query($update);
      if($data['status'] == 'Canceled'){
            $scmd = 'Refunded';
      $simpan = mysql_query("UPDATE user SET balance=balance+$saldo WHERE username = '$buyer'");
      $simpan = mysql_query("UPDATE order_history SET status = '$scmd' WHERE order_id = '$no'");
      } else {
            $scmd = 'Error';
      $simpan = mysql_query("UPDATE order_history SET status = '$scmd' WHERE order_id = '$no'");
      }
   } else if($status == 'Processing'){
      $scmd = 'Processing';
      $update = "update order_history set status = '$scmd' where order_id = '$no'";
                $exe = mysql_query($update);

   } else {
      echo '-';
   }

if ($json_result['error'] == TRUE) {
	echo "GAGAL MENGECEK ORDERAN, PESAN : ".$json_result['error'];
	echo "<br>";
} else {
	echo "STATUS ORDER : ".$json_result['status'];
		echo "<br>";
}

}
