如果条件似乎不适用于在线托管，则内部嵌套的MySQL Query？

Question

如果从条件发送嵌套的MySQL查询时，我将重定向到同一页面，但该查询似乎无法正常工作。

这是我的嵌套查询。

在这里，我正在接收来自表单的字符串输入，并希望将其发送到数据库。但是此查询不适用于cpanel托管。虽然这适用于本地XAMPP堆栈。

if (isset($_POST['submit_pending'])) {

  $pendingParticulars = $_POST['gr_particulars'];
  $pendingUnit        = $_POST['gr_unit'];
  $pendingRate        = $_POST['gr_rate'];
  $pendingReceived    = $_POST['gr_updateReceived'];
  $poNumber           = $_POST['gr_number'];
  $pendingAmount      = $pendingRate * $pendingReceived;

  $requiredUnit       =  $pendingUnit - $pendingReceived;
  $excess             =  $pendingReceived - $pendingUnit;
  $excess             =  max(0, $excess);
  $requiredUnit       =  max(0, $requiredUnit);
  $pendingShortage    =  $pendingUnit - $pendingReceived;
  if ($requiredUnit   == 0) {

    $submitGoodsQuery = "INSERT INTO goods_received (po_number, particulars, unit, actual_received, shortage, accepted, rejected, pending, rate, amount, status) VALUES ('$poNumber', '$pendingParticulars', '$pendingUnit', '$pendingReceived', '$requiredUnit', '$pendingReceived', 0, '$requiredUnit', '$pendingRate', '$pendingAmount', 'Received')";

    $submitGoodsResult = mysqli_query($connection, $submitGoodsQuery);

    if ($submitGoodsResult) {

      $updateGoodsPO = mysqli_query($connection, "DELETE FROM pending_goods WHERE po_number = '$poNumber' ");

      header("Refresh:0");

    } 

  } elseif ($requiredUnit > 0) {

    $submitGoodsQuery = "INSERT INTO goods_received (po_number, particulars, unit, actual_received, shortage, excess, accepted, rejected, pending, rate, amount, status) VALUES ('$poNumber', '$pendingParticulars', '$pendingUnit', '$pendingReceived', '$pendingShortage', 0, '$pendingReceived', 0, '$requiredUnit', '$pendingRate', '$pendingAmount', 'Received')";

    $submitGoodsResult = mysqli_query($connection, $submitGoodsQuery);

    if ($submitGoodsResult) {

      $newPoNumberQue   = mysqli_query($connection, "SELECT pending_number FROM pending_goods WHERE po_number =  '$poNumber' AND po_particulars = '$pendingParticulars' ORDER BY serial_number DESC ");

      $pendingCount     = mysqli_num_rows($newPoNumberQue);

      $updateGoodsPO = mysqli_query($connection, "DELETE FROM pending_goods WHERE po_number = '$poNumber' ");

      $insertNewVals = mysqli_query($connection, "INSERT INTO pending_goods (po_number, po_particulars, po_quantity, po_RateWithGst, goods_status) VALUES ('$poNumber', '$pendingParticulars', '$pendingShortage', '$pendingRate', 'Partially') ");


      header("Refresh:0");

    }
  }
 } // End submit pending
} // End get pending
