Validate jpg file - Laravel 5

Question

I’m trying to use the Validator to validate the upload file type but not sure if the syntax is correct

    $data=Input::all();

    $file  = $data["picture_url"]; 
    $rules = array('picture_url' => 'required|max:10000|mimes:jpg');

    $validator = Validator::make($file, $rules);

    if ($validator->fails()) {
        echo "Arquivo inválido";
    }else{

    }

because the following mistake is making

Errorexception in Factory.php line 91: Argument 1 passed to Illuminate Validation Factory::make() must be of the type array, Object Given, called in C: Users ssilva Documents wispot-manager vendor Laravel framework src Illuminate Support Facades Facade.php on line 219 and defined

Does anyone know how to solve?

Answer 1

Here’s the problem. In Laravel, when you take an index of an input referring to an upload file, it returns an object from Symfony called Symfony\Component\HttpFoundation\File\UploadedFile\FilesBag (when you have more than one upload file) or Symfony\Component\HttpFoundation\File\UploadedFile.

In that case, you must pass the array containing the following pair ['nome_do_indice_do_input' => 'valor_do_indice'].

So instead of doing this:

$data = Input::all();

 $file  = $data["picture_url"];

Do so:

  $file  = Input::only('picture_url')

  Validator::make($file, $rules);

Thus, it will only pick up the index picture_url and return a array containing key and field value. Thus, the validation should work as expected.

You can also optionally keep your current code by changing only the line referring to the Validator::make, thus:

 Validator::make(['picture_url' => $file], $rules);

Answer 2

The $file passed as argument in Validator has to be an array to compare with $Rules, because the way you are using the variables you are not getting the file. you can do it this way;

$data = Input::all();
$rules = array('picture_url' => 'required|max:10000|mimes:jpg');
$validator = Validator::make($data, $rules);
