Creating default object from empty value in Laravel 6.2

Question

I want to Update this data in database.

error :

ErrorException
Creating default object from empty value

i get error in this line :

$user->name = $request->name;

My Controller code is :

public function update(Request $request, $id)
{
    $this->validate($request, [
        'name' => 'required|max:255',
        'mobile' => 'required|numeric|regex:/(0)[0-9]/|not_regex:/[a-z]/|digits:11',
        'national_code' => 'required|numeric|regex:/(0)[0-9]/|not_regex:/[a-z]/|digits:10',
        'avatar' => 'required|mimes:jpg,jpeg,png',
    ]);

    $id = (int)$id;
    $user = User::findOrFail($id);
    $user->name = $request->name;
    $user->mobile = $request->mobile;
    $user->national_code = $request->national_code;
    $user->province = $request->province;
    $user->city = $request->city;
    $user->address = $request->address;
    $user->postcode = $request->postcode;
    $user->active = $request->active;
    $user->avatar = $request->avatar;


    if(! is_null($request->password)) {
        $request->validate([
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);

        $user->password = $request->password;
    }

    $user->active = $request->active ? 1 : 0;

    if ($request->role_id) {
        $user->syncRoles($request->role_id);
    }
    $user->save();

    $notification = array(
        'message' => 'Success !',
        'alert-type' => 'success'
    );

    return redirect(route('management.users.index'))->with($notification);
}

Route :

Route::resource('users', 'UserController');

Thank you

I don't think Route has anything to do with this error !! But i added. — MNamazi

first update your function header to this public function update(Request $request, User $user) and you could use it directly without useing findorfail — Joseph

Try this:

$user = User::find($id)

or this:

$user = User::where('id', $id)->first();

And check if in your User Model:

protected $fillable = [
    'name','mobile', 'national_code', 'city', 'province', 'address', 
     'postcode', 'active', 'avatar',
];

laravel.com/docs/5.7/eloquent in documentation you can show why not work, findOrFail is for Exception capture
