    if($query){
    foreach ($query->result() as $row);
    }

Answer 1

Clearly you The model is not written properly and to corrent this simple do this

1.) I put a default value on $t

2.) I put the query >> loop on the inside function

wandad

so it can be executed once called from controller

function wandad() {
    $query = $this->db->query("SELECT * FROM `rand` WHERE `used` = 0 LIMIT 0, 1");
    $t = "";
    if($query){

       foreach ($query->result() as $row){
          $t = "EXAMPLE/{$row->code}".'<br>';
       }
     }

    return $t;
    }
