我尝试解决标题，但是我真的很想知道解决方案，哦，有错误的代码在这里：

<?php
class Schedules extends CI_Controller {


function display($query_id = 0, $sort_by = 'event_name', $sort_order = 'asc', $offset = 0) {

    $limit = 20;
    $data['fields'] = array(
        'event_id' => 'ID',
        'event_name' => 'Title',
        'schedule' => 'Schedule',
        'date_expired' => 'Expired',
        'clientname' => 'Clientname',
        'cost' => 'Cost'
    );
    $this->input->load_query($query_id);

    $query_array = array(
        'event_name' => $this->input->get('event_name'),
        'date_expired' => $this->input->get('date_expired'),
        'length_comparison' => $this->input->get('length_comparison'),
        'date_expired' => $this->input->get('date_expired'),
    );
    $data['query_id'] = $query_id;

    $this->load->model('Schedule_model');

    $results = $this->Schedule_model->search($querry_array, $limit, $offset,     $sort_by, $sort_order); // this is line number 27 …
