Laravel 5.4 current id insert eloquent - php

Question

When register at Laravel using eloquent, my PK field at table users is userid [auto increment] I want to insert the current id at the same time when I run the User::create(); to different field (create_by [int]) so the create_by field will be filled with the same value as the primary key field userid, like this code:
User::Create([
'user_email' => $data['user_email'],
'user_password' => bcrypt($data['user_password']),
'first_name' => 'John',
'last_name' => 'Doe',
'department_id' => 1,
'user_level' => 1,
'create_date' => Carbon::now('Asia/Jakarta'),
'create_by' => // value same as userid the PK
])
How to get the current id to be used in different field?
I actually try some trick to get the id like this:
User::insertGetId([
'user_email' => $data['user_email'],
'user_password' => bcrypt($data['user_password']),
'first_name' => 'John',
'last_name' => 'Doe',
'department_id' => 1,
'user_level' => 1,
'create_date' => Carbon::now('Asia/Jakarta')
])
It was good to return the inserted id, but my expectation is I want to save the current id to the create_by field at the same time user_id was inserted, not after the data was saved.

Answer 1

You can try
$user = User::create([...]);
$user->create_by = $user->id;
$user->update();
Update
You can get the last user in the database. But be aware this is not 100% safe.
$lastUser = User::orderBy('id', 'desc')->first();
$user = User::create([
...
'create_by' => $lastUser->id + 1
]);

Might be its not a good way but it will work fine Try it
I am assuming db fields please review query as desired. Its a hint to work
1st need to get max id of user as
$users = User::whereRaw('id = (select max(`userid`) from users)')->first();
$create_by= $users->id+1;
//dd($create_by);
//die;
If you remove commented code it will give you next id now pass this variable as
'create_by' => $create_by,

Answer 3

You can do it by:
$user_save_obj = User::Create([
'user_email' => $data['user_email'],
'user_password' => bcrypt($data['user_password']),
'first_name' => 'John',
'last_name' => 'Doe',
'department_id' => 1,
'user_level' => 1,
'create_date' => Carbon::now('Asia/Jakarta')
])
$last_inserted_id = $user_save_obj->id;
$user_update_obj = User::find($last_inserted_id);
$user_update_obj->created_by = $last_inserted_id;
$user_update_obj->save();
