Question

我在autoload配置中已自动加载库site_model，这是我得到的错误：

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Site::$Site_model

Filename: controllers/site.php

Line Number: 16

Fatal error: Call to a member function add_record() on a non-object in /Applications/XAMPP/xamppfiles/htdocs/BLOCK/application/controllers/site.php on line 16

控制器：

<?php
class Site extends CI_Controller {

function index(){

    $this->load->view('option_view');
}

function create(){

    $data = array(
        'subject' => $this->input->post('subject'),
        'body' => $this->input->post('body')
    );

    $this->Site_model->add_record($data);
    $this->index();

}

}


?>

模型：

<?php

class Site_model extends CI_Model {

function get_records()

{
    $query = $this->db->get('items');
    return $query->result();
}

function add_record()
{
    $this->db->insert('items', $data);
    $return;
}

function update_record()
{
    $this->db->where('id', 1);
    $this->db->update('items', $data);

}

function delete_record()
{
    $this->db->where('id', $this->url->segment(3));
    $this->db->delete('items');

}

}





?>

和视图：

<title>option_view</title>
<style type="text/css" media="screen">

</style>
</head>

<body>
<h2>Create</h2>
<?php echo form_open('site/create'); ?>

<p>
    </label for="subject">Subject</label>
    <input type="text" name="subject" id="subject">
</p>

<p>
    </label for="body">Body</label>
    <input type="text" name="body" id="body">
</p>
<p>
<input type="submit" value="Submit">    
</p>
<?php echo form_close();?>
 </body>
 </html>

你们觉得怎么样？

非常感谢

Answer 1

$this->load->model('Site_model'); # <- add this
$this->Site_model->add_record($data);

Answer 2

你的代码很好......但是你忘记了简单的事情。你忘记在控制器中给出以下内容“__Construct（）”

$this->load->model('your modelname');

就是这样。每个人都很好。

Answer 3

添加构造函数。然后它将有助于调用模型。

<?php
class some_controller extends CI_Controller{

    public function __construct()
    {
        parent::__construct();
        $this->load->model('site_model');

    }
    function index()
    {
        $this->load->view('your_view');
    }
    function create()
    {
        $data = array(
            'test1' => $this->input->post('test1'),
            'test2' => $this->input->post('test2')
            );
        $this->site_model->add($data);
        $this->index();
    }

}

Answer 4

在 config-autoload.php 上添加“Site_model”，如下所示：

$autoload['model'] = array('Site_model');

消息：未定义属性：Site :: $ Site_model - CodeIgniter
