我在codeigniter中遇到了订单问题

Question

For some reason when I do order by Date_Scheduled desc it is still leaving the oldest date first. I am trying to get it so that the newest date shows first and oldest date last. Not sure is I am writing this correctly.

Here is my model it is the get employee function.

<?php

class Employee_model extends CI_Model 
{

    public function insert_employee($data)
    {
    $this->db->insert('employee_list',$data); 
return $this->db->insert_id(); 
    }
    public function get_employee()
    {
        $this->db->select('*');
        $this->db->from('employee_list');
        $this->db->where('status',1);
        $this->db->order_by ("Date_Scheduled", "desc"); 
        $this->db->order_by("Scheduled_Area", "desc");
        $this->db->order_by("Time_Reported", "desc");  




        $query =$this->db->get();
        return $query->result();
    }
    public function delete_employee($id,$data)
    {
        $this->db->where('id',$id);
        $this->db->update('employee_list',$data);
            return print_r($data);


    }
    public function edit_employee($id)
    {
        $this->db->select('*');
        $this->db->from('employee_list');
        $this->db->where('id',$id);
        $this->db->where('status',1);
        $query =$this->db->get();
        return $query->result();

    }
    public function update_employee($data,$id)
    {
        $this->db->where('id',$id);
        $this->db->update('employee_list',$data);
        return print_r($data);

    }
}

Answer 1

This answer solves part of your problem, because you should handle dates with the correct column type date and not varchar.

If the result of your query always returns ORDER BY ASC, you can flip the array.

array_reverse($this->Employee_model->get_employee());
