return view('admin.product.create',compact('categories'));
}
public function store(Request $request)
{
$formInput = $request->except('image');
$image = $request->image;
if($image){
$imageName = $image->getClientOriginalName();
$image->move('images', $imageName);
$formInput['image']=$imageName;
}
Product::create($formInput);
return redirect()->route('admin.index');
}
any help will be appreciated

Answer 1

should be:
action="{{route('product.store')}}"
The route product.create expects GET header for showing a register form

Answer 2

i forget to add name to the form now after adding name i get alle field except image

Answer 3

I tried all above answers and still had this problem. So I found out that my model was requiring the "fillable" property:
protected $fillable = ['name', 'status', 'etc','etc2'];
This solved the issue and now I can post/put/delete.
Also, in my routes file instead of using one route to each action, I simply use, for example:
Route::resource('user', 'v1\UserController');
