                        }

update dont work…
Where is my mistake?
Need help!

>Solution :

Since you’re already assigning array value to the $arFields, you don’t need to initialize it as empty array. Change your code to this (remove [] from $$arFields)

$arFields = array(
    'lotid' => $lotid,
    'lot' => $lot,
    'type' => $type,
    'status' => $status,
    'price' => $price,
    'pricesq' => $pricesq,
    'area' => $area,
    'floor' => $floor,
    'height' => $height
);

Result:

array:9 [
  "lotid" => 1
  "lot" => 1
  "type" => 1
  "status" => 1
  "price" => 1
  "pricesq" => 1
  "area" => 1
  "floor" => 1
  "height" => 1
]

The way you wrote it, your array has one element, which has a value of array:

array:1 [
  0 => array:9 [
    "lotid" => 1
    "lot" => 1
    "type" => 1
    "status" => 1
    "price" => 1
    "pricesq" => 1
    "area" => 1
    "floor" => 1
    "height" => 1
  ]
]

And $flatBuilder->update($arFields) is using that element (0 in this case), to find the relevant column.
