未定义变量：form_data (Laravel 5.7)

Question

Controller store method:

public function store(Request $request){
   $request->validate([
      'name' => 'required',
      'email' => 'required|email',
      'number' => 'required|unique:crud|numeric',
      'message' => 'required',
   ]);

   Crud::create($form_data);

   return redirect('crud')->with('success', 'Data Added successfully');
}

Exception:

Undefined variable: form_data

Answer 1

You're using the $form_data variable, but you never defined it in your function. Maybe you wanted to put the form data inside a variable, and then use it to store some data? If that's the case, do something like this:

$form_data = $request->input(); //Get form data from $request
Crud::create($form_data); 

Answer 2

Try. you are using form_data variable but it does not define anywhere

so just put this all code in your controller

public function store(Request $request)
{
    $form_data = $request->all();

    $request->validate([
      'name' => 'required',
      'email' => 'required|email',
      'number' => 'required|unique:crud|numeric',
      'message' =>'required',
    ]);

    Crud::create($form_data); 

    return redirect('crud')->with('success','Data Added Successfully.');
}
