    public function storeskills($skills,$id) {     $skills = "16,13";     $id = "150";     if(!empty($skills)){         $userskillsobj = orm::factory('userskill');     $userskills = explode(',',$skills);     foreach($userskills $skill)     {            //   $userskillsobj = orm::factory('userskill'); if statement here,                                                   //records getting added fine.         $userskillsobj->user_id = $id;         $userskillsobj->skills_id = $skill;         $ids = $userskillsobj->save();       }     }  } 

move line creates object within foreach loop. having outside means you're referencing same object, therefore final (second) loop saves on first one, making 13.

example:

foreach($userskills $skill) {        $userskillsobj = orm::factory('userskill');     $userskillsobj->user_id = $id;     $userskillsobj->skills_id = $skill;     $ids = $userskillsobj->save(); }
