Answer 1

for ($i = 0; $i < $count; $i++) {
  $this->data["schedule_count"] = $count;
  $this->data["user_travels"][$i] = $this->travel_order_model->get_travel_schedule($this->data["user_dates"][$i]->id);
}
$this->load->view('your_view_file', $data);

您的查看文件，您可以通过这种方式打印数据，

foreach($user_travels as $travelData){
    print_r($travelData);
}

Answer 2

for ($i = 0; $i < $count; $i++) {
  $this->data["schedule_count"] = $count;
  // pass Id 
  $this->data["user_travels"][$i] = $this->travel_order_model->get_travel_schedule($this->data["user_dates"][$i]->getId());
}
