Laravel: withInput - htmlentities() expects parameter 1 to be string, array given

Question

i'm suffering problems with the "withInput" on laravel. I'm trying make return when have errors on validation of controller with the inputs written before of submit, using follow lines:

$validator = Validator::make(Input::all(), [
    "rsocial" => "required",
    "cidade_id" => "required",
    "status_id" => "required",
]);

if ($validator->fails())
    return redirect()->route("clientesCadastrar")->withErrors($validator)->withInput();

But I'm having problems with the result, with the following error:

ErrorException in helpers.php line 531: htmlentities() expects parameter 1 to be string, array given

What I do?

Answer 1

The back() function generates a redirect response to the user's previous location.

Back-Helper Function - Laravel Docs

This may help:

if ($validator->fails()) {
    return back()
        ->withInput()
        ->withErrors($validator);
}

Answer 2

This usually happens because of an array getting using as a string, in a blade template. Can you post the complete stack trace?
