How to add and update in one api in laravel - php

Question

I am trying to add and update using the same API, currently, I can add but I am not clear about how to update using the same API.
I am adding folders against id and my body response looks like this:
{
"id": "2",
"folder_detail": [1,3,4]
}
I can add folders with id 1,3 and 4 against id 2 but next time when I hit the same API with folder[1,3,5] it should update folders details not should add again, I can do that by making separate API but I want to do that in one API.
My Controller code:
try {
$folder = Doctor::where('id', $request->get('id'))->first();
$folder->doctor()->attach($request->get('folder_detail', []));
DB::commit();
return response([
'status' => true,
'message' => 'Folder detail added',
], 200);
} catch (\Exception $ex) {
DB::rollback();
return response([
'status' => false,
'message' => __('messages.validation_errors'),
'errors' => $ex->getMessage(),
], 500);
}
}
public function doctor()
{
return $this->belongsToMany('App\Folder', 'folder_details');
}
Your help will be highly appreciated?

Answer 1

Okay so after our back and forth in the comments I think you are looking for something like this:
$folders = $request->get('folder_detail', []);
foreach($folders as $folder) {
$record = Folder::firstOrNew(['id', $folder]);
$record->doctor_id = $request->id;
// You can add your own records here, or use the 'fill' function
}
So, this way, you loop through all your folders. Check if the folder with the specific ID already exists, if it does not, it creates a new one. The doctor is linked through the doctor_id on your record.

Answer 2

Find record if exist then update otherwise create
$post = $request->all();
$doctor = Doctor::find($post['id']);
if($doctor){
$doctor->update([
//your data for update doctor model
]);
//remove old folders which is related with this doctor
Folder::where('doctor_id', $doctor->id)->delete();
//add current data of folder
if(!empty($post['folder_detail'])){
foreach($post['folder_detail'] as $folder){
Folder::create([
'doctor_id' => $doctor->id,
'folder_detail' => $folder
]);
}
}
//return your response here
} else {
$doctor = Doctor::create([
//data for create doctore
]);
//add current data of folder
if(!empty($post['folder_detail'])){
foreach($post['folder_detail'] as $folder){
Folder::create([
'doctor_id' => $doctor->id,
'folder_detail' => $folder
]);
}
}
//return your response here
}
