Accessing errors in a controller from a redirect Laravel

Question

As you may expect, when validation fails, I created a redirect.

return Redirect::to('search')->withErrors($v->messages())

I can access it in the view with out a problem, but I would like to do something different. I have an ErrorPartial.blade.php, which I would like to be passed to my search view.

return View::make('search.searchForm')
        ->with('title', 'Search Page')
        ->with('components', Subject::select('Component')->distinct()->get())
        ->with('measurementRow',$measurementRow)
        ->with('races', Race::parseRaceTable())
        ->with('errorPartial', View::make('errorPartial')
                ->with('errors',$v->messages())
                ->render())
        ;

The Problem is I don't have access to $v in this controller function. Can I access the errors that are going to be passed to the view some how? I've tried this:

return Redirect::to('search')->withErrors($v->messages())
            ->with('v', $v);

But I get this error.

Serialization of 'Closure' is not allowed

I could just create the Partial view in my search view but I was wondering if their was a way to do it this way. If anyone knows which would be more efficient or GPP then I wouldn't mind knowing that as well.

Thanks

Laravel stores the errors in the Session.

And all the functions available in blade are coming from ViewErrorBag class.

use Illuminate\Support\ViewErrorBag;
...
$errors = session()->get('errors', app(ViewErrorBag::class));

This approach is preferred because it returns empty error bag if there is no errors in the session. It means that you can call $errors->any() on this object without expecting to have an error saying

Call to a member function any() on null

You can always find an implementation in source code following this advice

The $errors variable is bound to the view by the Illuminate\View\Middleware\ShareErrorsFromSession middleware, which is provided by the web middleware group. When this middleware is applied an $errors variable will always be available in your views, allowing you to conveniently assume the $errors variable is always defined and can be safely used.

Answering the question to close it as an open question.

Laravel stores the errors in the Session, which can be access like so:

$errors = Session::get('errors');
