I got this error when I tried to update data users. I have browse to other source but don't found answer from my problem.

ErrorException
Creating default object from empty value
http://localhost:8000/ec-admin/users/updateact/{$users->id}

This is my user controller.

namespace App\Http\Controllers;

use Illuminate\Support\Facades\Auth;
use Illuminate\Http\Request;
use Illuminate\Support\Str;
use App\User;
use File;

public function updateact($id, Request $request)
{
    // Menyiapkan data gambar yg diupload ke variable $file
    $file_name = $request->hidden_image;
    $file = $request->file('file');
    if($file != '')
    {
        // Validasi data
        $this->validate($request,[
            'name'          => 'required|alpha',
            'email'         => 'required|email',
            'level'         => 'required|alpha',
            'password'      => 'required',
            'file'          => 'required|file|image|mimes:jpeg,jpg,png|max:1048'
        ]);

        $file_name = time()."_".$file->getClientOriginalName();

        // Isi dengan nama folder tempat kemana file diupload
        $upload_directory = 'p_users';
        $file->move($upload_directory, $file_name);

        // Hapus file
        $gambar = User::where('id',$id)->first();
        File::delete(public_path('p_users/'.$gambar->file));

     }
    else
    {
        // Validasi data
        $this->validate($request,[
            'name'          => 'required|alpha',
            'email'         => 'required|email',
            'level'         => 'required|alpha',
            'password'      => 'required'
        ]);

    }

    // Update data
    $users = User::find($id);
    $users->name        = $request->name;
    $users->email       = $request->email;
    $users->level       = $request->level;
    $users->password    = $request->password;
    $users->file        = $file_name;
    $users->save();

    return redirect('/ec-admin/users')->with('usrsupdateno', 'Data update Successfully!');
}

    </div>
</form>

This is my route, I hope this help.

Route::get('/ec-admin/users/update/{id}', 'UsersController@update')->name('usrupdate');
Route::put('/ec-admin/users/updateact/{id}', 'UsersController@updateact');

CodePudding user response：

in your form action change {$users->id} to {{$users->id}} it would work

but for best practice you should assign a name to your route then use the route helper

CodePudding user response：

This error is triggered when yourObj is NULL or not yet initialized: That's because your $users = User::find($id); return NULL ,

Your form URL is incorrect and so Eloquent can't find your expected User.

Best practice

Change your **PUT** route to :

Route::put('/ec-admin/users/updateact/{id}', 'UsersController@updateact')->name('act.update');

Then in your <form> change action="/ec-admin/users/updateact/{$users->id}" to

action="{{ route('act.update',$users->id) }}"

Simple solution

Change your form action from action="/ec-admin/users/updateact/{$users->id}" to

action="/ec-admin/users/updateact/{{ $users->id }}"
