【问题描述】:
我正在使用 codeigniter latestversion,并且我已经安装了 phpactiverecord 版本 0.0.2,
但是当我用这种方法从数据库中检索数据时
$users = Users::find('all') // return nothing
i did var_dump($users);
output::
array (size=2)
0 =>
object(Users)[39]
public 'errors' => null
private 'attributes' (ActiveRecord\Model) =>
array (size=9)
'id' => null
'username' => null
'email' => null
'password' => null
'active' => int 0
'activation' => null
'ip' => null
'created' => null
'lastaccess' => null
private '__dirty' (ActiveRecord\Model) => null
private '__readonly' (ActiveRecord\Model) => boolean false
private '__relationships' (ActiveRecord\Model) =>
array (size=0)
empty
private '__new_record' (ActiveRecord\Model) => boolean true
1 =>
object(Users)[40]
public 'errors' => null
private 'attributes' (ActiveRecord\Model) =>
array (size=9)
'id' => null
'username' => null
'email' => null
'password' => null
'active' => int 0
'activation' => null
'ip' => null
'created' => null
'lastaccess' => null
private '__dirty' (ActiveRecord\Model) => null
private '__readonly' (ActiveRecord\Model) => boolean false
private '__relationships' (ActiveRecord\Model) =>
array (size=0)
empty
private '__new_record' (ActiveRecord\Model) => boolean true
我正在尝试找出问题所在,请帮忙
///// Model
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Users extends ActiveRecord\Model {
public function __construct() {
parent::__construct();
}
}
/* End of file user.php */
/* Location: ./application/models/user.php */
?>
///// Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class User extends MY_Controller {
public function __construct() {
parent::__construct();
}
public function index()
{
$user = Users::all();
var_dump($user);
foreach ($user as $u) {
echo $u->username.'<br/>';
}
## Rendering the view
$this->template->view($this->temp, array('page'=>'backend/users'), NULL);
}
}
/* End of file users.php */
/* Location: ./application/controllers/users.php */
?>
////// Autoload
$autoload['sparks'] = array('php-activerecord/0.0.2');
【问题讨论】:
-
所以它“什么都不返回”,但是转储变量会得到你所期望的结果吗?那么,您如何确定它什么也不返回呢?
-
数组为空,它应该包含来自数据库的数据.....即使当我回显 $u->username 时,什么也没有出现
-
用户名是
null,所以什么都不会出现。 (这是一个 PHP 的东西。尽可能逃跑。)似乎问题在于你如何保存记录,而不是读取它们。 -
我只是获取数据,我没有保存,
-
我只是不知道为什么它不起作用,我只是决定使用 php-activerecord,我只是在关注文档但没有运气......
