Mohon bantuan model dan view pengembangan swarakalibata

Assalamualaikum Warahmatullahi Wabarakatuh...
 
Model  masih sama seperti swarakalibata sebelumnya, :
 
    function coba($id){
        return $this->db->query("SELECT * FROM modul,users_modul,users 
			WHERE users.id_session=users_modul.id_session
			AND modul.id_modul=users_modul.id_modul
			AND modul.publish='Y' AND modul.status='user' AND modul.aktif='Y' AND modul.id_menu='$id'");
    }
 
Permasalahan pada View menu dan modul dinamis user dengan perintah seperti ini :
 
}else{
				$aksesmodul = $this->model_app->modul_akses();
				foreach ($aksesmodul->result_array() as $x){
				echo "<li class='treeview'>
					<a href='".base_url()."#'><i class='$x[iconn]'></i><span>$x[nama_menu]</span>
					<span class='pull-right-container'><i class='fa fa-angle-left pull-right'></i></span></a>
 
					<ul class='treeview-menu'>";
						$mainuser = $this->model_app->coba($x[id_menu]);
						foreach ($mainuser->result_array() as $muser) {
							echo "<li><a href='".base_url()."mis/$muser[link]'><i class='fa fa-circle-o'></i> $muser[nama_modul]</a></li>";
						}
					echo "</ul>
				</li>";
				}	
			}
