Question

笨
我正在使用下拉菜单我的问题是我没有从数据库中获取值

这是我的代码

表格字段：

id，name，category_online

模型代码 - 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();
}
}
?>

这是我的Controller -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);
}
}

这是我的view-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();
?>

这就是输出看起来像

您需要从模型文件中返回 $ data ，例如

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;
 }
