How do I access to a variable inside a function

Question

I mean,I have

public class MyClass{

   public $variable="myValue";

   protected $rules = [
        'variable' = 'required';
    ]

public function render()
{

    return view('livewire.my-view');

}

public function submit()
{
      $db = DB::connection ('myConnection')

     $this->validate();
     $db = DB::select('INSERT INTO my_table (variable) VALUES (:variable)', ['variable'=>$variable]);

}

But when I execute the script (i have a form and a submit button)

It returns

Error, variable "variable" undefined

Hello @aakash,

I guess jQuery  based on the MIME type of the response, so that you can potentially accept JSON or some other format.So try look for that datatype first

I have try that out using this would give I get this error "Has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource." .any idea about this?

---

To solve this error just add the following script in the beginning of your PHP page which handles the request:

<?php header('Access-Control-Allow-Origin: *'); ?>

Thanks it worked to resolve this error but how can I remove 

Error, variable "variable" undefined??

---

I think you've to use $this->variable

Ahh...great it worked....tysm
