Question

我在CodeIgniter中有通知系统，当我从Notification类中提取结果时，我创建了一个视图页面，所以我需要帮助，因为我没有任何结果。

这是我的观点 nombre.php：

<?php
if (!isset($_SESSION['id'])) exit;
include ("notif_model.php");

$notification = new notif_model();

$notifications = $notification->getcountNotif();
echo $notifications;


?>

这是我的班级 notif_model.php：

class notif_model extends CI_Model
{

    var $type;//reservation request, comment, message
    var $to_user;
    var $from_user;
    var $reference;//comm id, message id
    var $timestamp;
    var $newcount;

    function __construct()
    {
        parent::__construct();
        $this->load->library('session');
    }

    function insertNotification($notification)
    {
        $this->db->insert('notification',$notification);
        return $this->db->insert_id();
    }

    function countNotif()
    {
        $this->db->select('*');
        $this->db->where('to_user',$this->session->userdata('id'));
        $this->db->where('seen',0);
        $query = $this->db->get('notification');
        $res = $query->num_rows();
        return $res;
    }

}
?>

Answer 1

function countNotif()
{
    $this->db->select('*');
    $this->db->where('to_user',$this->session->userdata('id'));
    $this->db->where('seen',0);
    $query = $this->db->get('notification');
    $res = $query->num_rows();

    echo $this->db->last_query(); exit; // will print the query string

    return $res;
}

运行并检查查询....
