I wanna update options cart, I have many options inside, but I just want only one option to change, and I cannot do it

Here’s my code

Cart::add([
'id' => 1, 
'name' => 'Keyboard', 
'qty' => 30, 
'price' => 399, 
'options' => [
'item_code' => 'KEY01', 
'dimension' => '30cm x 60cm', ...etc]
]);

and then I want to change options

Here’s my code

Cart::update(
$rowId, [
'qty' => 60, 
'price' => 299, 
'options' => [
'item_code' => 'KEY02']
]);

and then the result options only item_code, and others are disappear I want the others options still there, how to handle this?

Sorry for bad English

Answer

Please try by following code.

$item = Cart::get($rowId);
$option = $item->option->merge(['item_code' => 'KEY02']);

Cart::update(
    $rowId, [
    'qty' => 60, 
    'price' => 299, 
    'options' => $option
]);
