Question

我的代码运行良好，但我得到此错误消息：未定义的属性：stdClass :: $日期，我不知道这个错误来自哪里，只要我看到我的代码是正确的。问题出在我的foreach代码中这是我的控制器

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
session_start();

class News_and_events extends CI_Controller {
  public function __construct(){
      parent::__construct();
      $this->load->library('form_validation');
      $this->load->model('admin_model', 'am');
  }

  public function index(){
    if($this->session->userdata('logged_in')){
      $this->data['title'] = 'News and Events | Spring Rain Global Consultancy Inc Admin Panel';
      $this->data['logout'] = 'Logout';

      $session_data = $this->session->userdata('logged_in');
      $this->data['id'] = $session_data['id'];
      $this->data['username'] = $session_data['username'];

      $this->data['allData'] = $this->am->getAllData();


      $this->load->view('pages/admin_header', $this->data);
      $this->load->view('content/news_and_events', $this->data);
      $this->load->view('pages/admin_footer');
    }else{
      redirect('login', 'refresh');
    }
  }
}

我的模特

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

Class Admin_model extends CI_Model{
    public function saveData($array){
      $this->db->insert('news_and_updates', $array);
    }

    public function getAllData(){
      return $this->db->select(
                          'news_and_updates.Event',
                          'news_and_updates.Description',
                          'news_and_updates.Date'
                        )
                  ->from('news_and_updates')
                  ->order_by("Date", "desc")
                  ->get()->result_object();
    }
}
?>

      $('#datepicker').datepicker({
        minDate: new Date(currentYear, currentMonth, currentDate),
        dateFormat: "yy-mm-dd"
      });

</script>

在我的foreach代码中错误是这一个$ allDatas-＆gt; Date;它说消息：未定义的属性：stdClass :: $ Date 那是我的表日期中的字段名称有人可以帮我搞清楚吗？任何帮助深表感谢！谢谢！找不到错误

Answer 1

在模型或控制器中 - 执行getAllData方法后：

echo the result of $this->db->last_query()

在数据库中手动执行返回的查询，然后修复查询

Answer 2

评论开始时，问题是日期不是从查询中生成的，这意味着该级别出现了错误，而不是输出本身。

确保查询正确，在您直接从控制器加载视图之前将其转储以查看它获得的内容，如果它没有获得日期，则您的问题可能在其他地方，可能在查询本身中。

消息：未定义属性：stdClass :: $ Date using codeigniter
