Codeigniter 房间预订表格验证

Question

我正在尝试使用form_validation 制作用于预订房间的表单，以在用户将数据输入表单时验证房间是否已被预订。我将输出显示到表格中。这是我的验证：

function add_room()
{
    $this->form_validation->set_rules('start', 'Start Date', 'required|is_unique[calendar.start]');
    $this->form_validation->set_rules('start_t', 'Start Time', 'required|is_unique[calendar.start_t]');
    $this->form_validation->set_rules('end_t', 'End Time', 'required|is_unique[calendar.end_t]');
    $this->form_validation->set_rules('room', 'Room', 'required|is_unique[calendar.room]');
    $this->form_validation->set_rules('title', 'Title', 'required|trim|xss_clean');
    $this->form_validation->set_rules('user', 'NRP', 'required|trim|xss_clean');
    $this->form_validation->set_rules('nama', 'Name', 'required|trim|xss_clean');
    $this->form_validation->set_rules('ext', 'EXT', 'required|trim|xss_clean');
    $this->form_validation->set_rules('topic', 'Topic', 'required|trim|xss_clean');
    $this->form_validation->set_rules('attend', 'Attendees', 'required|trim|xss_clean');

    if ($this->form_validation->run() == FALSE) {
        $this->form_validation->run('start_t');
    }
    elseif ($this->form_validation->run('start_t') == TRUE) {
        $this->form_validation->run('end_t');
    }
    elseif ($this->form_validation->run('end_t') == TRUE) {
        $this->form_validation->run('start');
    }
    elseif ($this->form_validation->run('start') == TRUE) {
        $this->form_validation->run('room');
    }
    elseif ($this->form_validation->run('room') == TRUE) {
        $this->form_validation->run();
    }
    elseif ($this->form_validation->run() == TRUE) {
        $this->calendar->add_room();
    } else {
        validation_errors();
        $this->conf->msg('danger');
    }
    redirect('calendar/meeting');


}

我知道我的代码很糟糕，但我仍然不确定如何制作 if 结构。我想要验证检查Start Time、End Time 和Start Date 处的Room 是否已被预订。如果它已被预订，则验证将是错误的并显示error message。我不太擅长CI。事实上，我是这个编程方面的新手。那么，我怎样才能在CI 预订合适的房间呢？感谢您的帮助。

将要验证的错误放入数组中

$config = 数组（ array('field' => 'bk_r_type_id', 'label' => 'bk_r_type_id Name', 'rules' => 'trim|required|max_length[100]') );

    $this->form_validation->set_rules($config);
