php - Laravel 5.2 Eloquent multiple select preg_replace(): Parameter mismatch, pattern is string while replacement is an array -

i've seen multiple different answers question, none of keep use of form model binding. seems form submitting tags array, should string. ideas?

controller:

/**  * save new news  *  * @param request $request  * @return mixed  */ public function store(newsrequest $request) {     // create news object , save form data     $news = news::create($request->all());  // rename image file , move public/images $image = $request->file('image'); $path = "/images/"; $ext = $image->getclientoriginalextension(); $name = str_random(12) . $ext; $image->move(public_path() . $path, $name); $news->image = $path . $name;  // save new image path news object $news->save();  //associate sandbox, if not $news->sandboxes()->sync($request->input('sandboxes'));  //populate news_tag pivot table chosen tags $news->tags()->sync($request->input('tags'));    return redirect()->action('fp\newscontroller@index'); } 

here's trace:
