-this code model 

    public function getidloaisp($loaispname){          //return loaisp::where('loaisp_name','=',$loaispname)->get();         return db::table('loaisp')->where('loaisp_name',$loaispname)->first();     }

-this error

errorexception (e_unknown) trying property of non-object open: e:\xampp\htdocs\www\daunhot\app\controllers\admincontroller.php

        $loaispname = input::get('loaispname');          $loaisp = new loaisp;           $datas = $loaisp->getidloaisp($loaispname);          $idloaisp = $datas->id; // error          $item = new sanpham;

when see error there 2 error: got nothing query(db::table('loaisp')->where('loaisp_name',$loaispname)->first();), or got array, if using ->get() instead of ->first() error. try use foreach on query result, or try use dd() function on result can see if empty or not. if empty porblem.
