How to queue the logics in controller - laravel

Question

I have used two logic in my controller in my laravel project
public function multiStore()
{
$user = User::create([
'name'=>$request->name,
'email'=>$request->email,
'password'=>Hash::make($request->name),
]);
$post = MyPost::create([
'name'=>$request->post_name,
'body'=>$request->post_body,
]);
return redirect()->to('/admin/home);
}
Is it possible to make like if user is created successfully only then the post will be created so that I can use post created by user relationship
I have tried something like if condition but it is not working

Answer 1

You can try the code bellow , I assume you have a user_id field in posts table since you mentio9ned a relation ship. This is not the best way but i try to keep things simple, so I just edited the code.
Note : make sure you listed all the table fields in protected $fillable in your model before using Create()
public function multiStore()
{
$user = User::create([
'name'=>$request->name,
'email'=>$request->email,
'password'=>Hash::make($request->name),
]);
if($user){
$post = MyPost::create([
'user_id' => $user->id
'name'=>$request->post_name,
'body'=>$request->post_body,
]);
}
return redirect()->to('/admin/home);
}

Enclose your query in database transaction
https://laravel.com/docs/5.8/database#database-transactions
Either you can:
DB::transaction(function() {
Model::create();
AnotherModel::create();
});
Or you can use the following to find and catch error...
DB::beginTransaction();
// Your queries here...
// Model::create();
// AnotherModel::create();
DB::commit();
