How to merge exists data with new data? - php

Question

Method 1 : Here I wrote the code for insert booking seat data into the database
Problem : When I book new seat it will creating new row so I'm getting duplicate rows so I tried method 2
Method 1 code :
$booking = new Bookings();
$booking->users_id = 4;
$booking->schedules_id = $schedules_id;
$booking->buses_id = $buses_id;
$booking->routes_id = $routes_id;
$booking->seat = implode(',', $seat);
$booking->price = $request->price;
$booking->profile = 'pending';
Method 2 : Here checking schedules_id equal to exists schedules_id then update seat and other data's
Problem : Insert new data updating old data
Method 2 code :
$booking = Bookings::updateOrCreate(
['schedules_id' => $schedules_id], // match the row based on this array
[ // update this columns
'buses_id' => $buses_id,
'routes_id' => $routes_id,
'seat' => json_encode($seat),
'price' => $request->price,
'profile' => 'pending',
]
);
// I don't know this is logically correct or wrong
My idea : Here I'm retrieving old data and storing into one variable then merging old data and new data into one column
Problem : Getting error.
My idea code :
$extSeat = DB::table('bookings')->select('seat')->get();
$booking = Bookings::updateOrCreate(
['schedules_id' => $schedules_id],
[ // update this columns
'buses_id' => $buses_id,
'routes_id' => $routes_id,
'seat' => implode(",", array_merge($seat,$extSeat)),
'price' => $request->price,
'profile' => 'pending',
]);
what i actually need ? : i need merge exists data with new data without updating.
Old data look like A1,B1
when insert new data like C1
i need data like this A1,B1,C1
I hope I explain clear enough. Any help is appreciated, thank you.

Answer 1

I don't know this is a correct logic or not but works for me, any other suggestions are welcome.
$extSeat = DB::table('bookings')->select('seat')->first();
$extSeat = explode(",", $extSeat->seat);
$booking = Bookings::updateOrCreate(
['schedules_id' => $schedules_id],
[ // update this columns
'buses_id' => $buses_id,
'routes_id' => $routes_id,
'seat' => implode(",", array_merge($seat,$extSeat )),
'price' => $request->price,
'profile' => 'pending',
]);
