Question

我想使用CodeIgniter创建分页但我收到以下错误

Fatal error: Call to a member function query() on a non-object in /home/eheuristic10/php/courtgenie/application/models/kicker_model.php on line 338

我的模特是

function ticketCount() {
    $query = $this->db->query("SELECT count(*) as c FROM  ci_ticket_details where userid='" . 2 . "' and activity_status = '0' LIMIT 1");
    $rows = $query->row_array();
    return $rows['c'];
}

我的分页类是

function attorney_request(){
    $this->load->library('pagination');
    $data['ticketCount'] = $this->kicker_model->ticketCount();
    $config = array();
    $config["base_url"] = 'http://localhost/courtgenie/index.php/kicker/attorney_request';
    $config["total_rows"] = $this->kicker_model->ticketCount();
    $config["per_page"] = 2;
    $config["uri_segment"] = 3;

    $this->pagination->initialize($config);
    $data["activeClient"] = $this->kicker_model->activeTicketsView($config["per_page"], $page);
    $data['pagination'] = $this->pagination->create_links();
    $this->load->view('attorney_request',$data);

    }
    else{
        redirect('home', 'refresh');
    }

}

如果我不使用分页类，那么我的分页将正常工作

Answer 1

您的SQL无效：

$this->db->query("SELECT count(*) as c FROM  ci_ticket_details where userid='" . 2 . "' and activity_status = '0' LIMIT 1");

您的用户ID不能是' . 2 . '。

您还在使用 CI ，但为什么不使用 ACTIVE RECORD 来调用这样一个简单的SQL调用？节省时间使用AR ...

同时...
您的if语句的缩进格式很差，而且它已被破坏，有一个孤独的else而您的attorney_request()过早终止。

在模型中尝试这个

function ticketCount() {
    $this->db->select('count(*) as c');
    $this->db->from('ci_ticket_details');
    $this->db->where('userid', 2);
    $this->db->where('activity_status', 0);
    $this->db->limit(1,0);
    $query = $this->db->get()->row();
    return $query->c;

}

分页在CodeIgniter中不起作用
