and php code:

$message = null; // message user      $locale = input::get('lang');      // item     $data = array(         'category' => input::get('category'),         'price' => input::get('price'),         'description' => input::get('description'),         'images' => json_decode(input::get('images')),         'time' => input::get('time'),         'type' => (input::get('type') == null) ? 0 : input::get('type'),     );       $validator = validator::make($data, array(         'description' => 'required',         'price' => 'required',         'category' => 'required',         'images' => 'required|max:10',         'time' => 'required',         'type' => 'required',     ));      if($validator->fails()) {                    return response::json(['success' => false, 'message' => $validator->errors()->first()]);     } 

it gets part validator fails. if dosnt fail, , data actualy sent server saves , good.

if helps can give link webpage can checked out.

edit------------- seems pictures cannot sent. individualy , others. , pictures can sent individualy not other. , pictures can sent individualy , other pictures can sent. really weird.

so true answer @barmar said. looked @ size of files i'm sending , seemed alright, didn't think didn't send images files data-url. , means file size didn't matter. , had increase actual post size.
