笨下拉值未顯示

Question

笨
我使用的下拉和 我的問題是，我不是從數據庫

這裏所獲得的價值是我的代碼

表字段：

ID，姓名，category_online

型號代碼 - category_model.php

<?PHP 
    class category_model extends CI_Model{ 
     public function __construct() { 
    parent::__construct(); 
    } 
public function get_all_online_select() { 
     $this->db->select('id, name'); //change this to the two main values you want to use 
     $this->db->from('category'); 
     $this->db->where('category_online', 1); 
     $query = $this->db->get(); 
     foreach($query->result_array() as $row){ 
      $data[$row['id']]=$row['name']; 
     } 
     return $query->result_array(); 
} 
} 
?> 

這裏是我的控制器-Welcome.php

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 
class Welcome extends CI_Controller { 
    public function __construct() { 
    parent::__construct(); 
    } 
function add_content() { 
     $data = array(); 
     $this->load->helper('form'); 
     $this->load->model('category_model'); 
     $data['select_options'] = $this->category_model->get_all_online_select(); 
     $this->load->view('add_content', $data); 
} 
} 

這是我的看法，add_content.php

<?php 
    echo form_open('save_content'); 
    echo form_fieldset(); 
    echo form_dropdown('categories', $select_options); 
    echo form_submit('category_submit', 'Submit'); 
    echo form_fieldset_close(); 
    echo form_close(); 
?> 

這是個什麼出來把看起來像

你需要從模型文件返回$數據像

public function get_all_online_select() { 
    $this->db->select('id, name'); //change this to the two main values you want to use 
    $this->db->from('category'); 
    $this->db->where('category_online', 1); 
    $query = $this->db->get(); 
    $data = array(); 
    $my_data = $query->result_array(); 
    foreach($my_data as $row){ 
     $data[$row['id']]=$row['name']; 
    } 
    return $data; 
}
