Multiple images uploaded with Laravel

I have trying to make multiple images function with Laravel but I have received


'Invalid argument supplied for foreach()'


This is the function in the controller

public function uploadSubmit() {

$files = Input::file('image');
$file_count = count($files);
$gallery = 0;

foreach($files as $file) {

$gallery = new Gallery;
$rules = array('file' => 'required');
$validator = Validator::make(array('file'=> $file), $rules);

if($validator->passes()){

$filename = str_random(20);
$file->move(public_path() . '/uploads', $filename . '.' . $file->getClientOriginalExtension());
$imagePath = '/uploads/' . $filename . '.' . $file->getClientOriginalExtension();

$image = Image::make(public_path() . $imagePath);

$image->save();
$gallery ++;
$gallery->image = $imagePath;
$gallery->save();
}
}
if($gallery == $file_count){
return Redirect::to('/admin/upload')->with('message', 'image added.');
}
else
{
return Redirect::to('/admin/upload')->withInput()->withErrors($validator);
}

}


When I
var_dump($files);
it returns
NULL
.

The form is

{{ Form::open() }}
{{ Form::file('image[]', array('multiple'=>true)) }}
<hr />
<button type="submit" class="btn btn-primary">upload</button>
{{ Form::close() }}


My route:

Route::get ('/admin/upload', ['uses' => 'AdminController@upload', 'before' => 'admin']);
Route::post('/admin/upload', ['uses' => 'AdminController@uploadSubmit', 'before' => 'csrf|admin']);

Answer

make File true when you create your form

{!! Form::open(array('route' => 'image.upload', 'method' => 'POST', 'files' => true)) !!}

{!! Form::open(array('route' => 'image.upload', 'method' => 'POST',   'files' => true)) !!}
    {{ Form::file('image[]', array('multiple'=>true)) }}
        <hr />
        <button type="submit" class="btn btn-primary">upload</button>           
{{ Form::close() }}

Your Function

public function uploadSubmit() {
    $files = Input::file('image');
    $file_count = count($files);
    foreach($files as $file) {
        $gallery = new Gallery;    
        $rules = array('file' => 'required');
        $validator = Validator::make(array('file'=> $file), $rules);
        if($validator->passes()){
            $filename = str_random(20). '.' . $file->getClientOriginalExtension();
            $file->move('uploads', $filename );
        $gallery->image = $filename;
        $gallery->save();
        }
   }
}
