laravel Form Request = if button was clicked

Question

I need to know which button was clicked inside a request form on laravel since i have Save and Update buttons.

App\Http\Requests\RegistrationRequest.php

public function rules()
{
    $myrule = [ 'name' => 'required', 'age' => 'required' ];

    if (isset($_POST['save']))
    {
        $myrule['application_form'] = 'required';
    }
    elseif (isset($_POST['update']))
    {
        $myrule['application_form'] = 'required_without:is_application_form';
    }

    return $myrule;
}

i need to know if the button that was click is Save or Update because I'm requiring for the application_form file field to be required if the Save button is clicked but I only require the application_form field if the is_application_form hidden field is empty.

the setup above is working for name and age field but ignores the codes inside the IF conditions.

In html

<button type="submit" name = "submit" value = "Save"></button>
<button type="submit" name = "submit" value = "Update"></button>

In code

if($request->submit == "Save")
{
......
}
else if($request->submit == "Update")
{
.....
}
