If you want the currently authorized user, just use app()->user(). Also, you can simplify a lot of your logic and make it much easier to read.
如果您想要当前授权的用户，只需使用app()->user(). 此外，您可以简化很多逻辑并使其更易于阅读。
auth()
->user()
->create($request->only([
'name',
'email',
'password'
]))
->clinic()
->create($request->only([
'clinic_name',
'telephone',
'address_1',
'address_2',
'city',
'postcode'
]));
return redirect('/home');

public function store(Request $request)
{
$user = App\User::create([
'name' => $request->name,
'email' => $request->email,
'password' => $request->password
]);
$clinic = App\Clinic::create([
'clinic_name' => $request->clinic_name,
'telephone' => $request->telephone,
'address_1' => $request->address_1,
'address_2' => $request->address_2,
'city' => $request->city,
'postcode' => $request->postcode
])
$user->clinics()->attach($clinic->id);
return redirect('/home');
}

Change your controller to this:
将您的控制器更改为：
public function store(Request $request)
{
App\User::create([
'name' => $request->name,
'email' => $request->email,
'password' => $request->password
]);
App\Clinic::create([
'clinic_name' => $request->clinic_name,
'telephone' => $request->telephone,
'address_1' => $request->address_1,
'address_2' => $request->address_2,
'city' => $request->city,
'postcode' => $request->postcode
]);
return redirect('/home');
}

I think problems with $fillable property, make sure to check it.
我认为 $fillable 属性有问题，请务必检查它。
