Codeigniter 控制器的构造函数中加载的模型不可被同一控制器的其他函数使用
我的模型:如下所示,非常基本
class User extends CI_Model
{
function __construct()
{
parent::__construct();
}
function getAll()
{
$this->db->order_by("lastName", "asc");
$this->db->order_by("firstName", "asc");
$this->db->order_by("userName", "asc");
$query = $this->db->get('user');
// test for result
if($query->num_rows() > 0)
{
return $query->result();
}
return NULL;
}
}
我的控制器:实际上是我控制器的一部分,每次通过默认路由加载用户/显示功能时,都会显示错误(进一步向下)。控制器构造函数中加载的模型是否可用于同一控制器中的所有其他功能?
class Users extends CI_Controller
{
function __contruct()
{
parent::__construct();
$this->load->model('user');
}
function display()
{
$data['users'] = $this->user->getAll();
$head['pageTitle'] = 'Users Panel';
$this->load->view('security/redirect');
$this->load->view('template/head', $head);
$this->load->view('user/usersPanel', $data);
$this->load->view('template/foot');
}
}
我的错误:在上面的控制器中引用行“$data['users'] = $this->user->getAll()”
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Users::$user
我的环境:
Codeigniter 2.1.0;
Mac Lion;
MAMP 2.0;
My model: as seen below, very basic
class User extends CI_Model
{
function __construct()
{
parent::__construct();
}
function getAll()
{
$this->db->order_by("lastName", "asc");
$this->db->order_by("firstName", "asc");
$this->db->order_by("userName", "asc");
$query = $this->db->get('user');
// test for result
if($query->num_rows() > 0)
{
return $query->result();
}
return NULL;
}
}
My controller: actually part of my controller, every time loading the users/display function by default route, the error (further down) shows up. Should a model loaded in a controller's contructor be available for all other function in the same controller?
class Users extends CI_Controller
{
function __contruct()
{
parent::__construct();
$this->load->model('user');
}
function display()
{
$data['users'] = $this->user->getAll();
$head['pageTitle'] = 'Users Panel';
$this->load->view('security/redirect');
$this->load->view('template/head', $head);
$this->load->view('user/usersPanel', $data);
$this->load->view('template/foot');
}
}
My error: refering to the line, "$data['users'] = $this->user->getAll()", in above controller

难道不应该这样:
像这样:
用构造替换构造。
Shouldn't this:
be like this:
replace contruct with construct.
难道不应该是这样
:
抱歉
还有模型名称:
$this->load->model('user_model');
类名 User_model 扩展了 CI_Model
我所有的 CI 项目都是这样设置的。

Shouldn't this:
be this:
sorry
also the model name:
$this->load->model('user_model');
and class name User_model extends CI_Model
All of my CI projects are set up this way.
