CodeIgniter params没有传递给库？

Ok I'm trying to pass parameteres to the constructor of my library I created to extend the CI_Form_validation class. Anyway, here is what I'm passing from my model:

好吧,我正在尝试将参数传递给我创建的库的构造函数,以扩展CI_Form_validation类。无论如何,这是我从模型中传递的内容:

$this->load->library('MY_Form_validation', array('config' => '', 'post' => $this->input->post()));

Then here is the MY_Form_validation library:

然后是MY_Form_validation库:

private $post;

    public function __construct($params) {
        parent::__construct($params['config']);
        $this->post = $params['post'];
    }

But it's saying I'm not passing anything in. Here are the error messages:

但是它说我没有传递任何内容。以下是错误消息:

Message: Missing argument 1 for MY_Form_validation::__construct(), called in H:\WD SmartWare.swstor\HALEY-HP\Source\DStable\stable\core\Loader.php on line 1099 and defined
Message: Undefined variable: params

EDIT On request, the whole class:

编辑根据要求,全班:

class MY_Form_validation extends CI_Form_validation {
    private $post;

    public function __construct($params) {
        parent::__construct($params['config']);
        $this->post = $params['post'];
    }
}

You need to just pass an empty array instead of an empty string as the first parameter to your constructor, which is sent to the parent:

您需要传递一个空数组而不是空字符串作为构造函数的第一个参数,该参数将发送给父级:

$this->load->library('MY_Form_validation', array('config' => array(), 'post' => $this->input->post()));

The CI Form Validation library actually initializes the config argument as such, this is the constructor from system/libraries/Form_validation.php:

CI表单验证库实际上初始化了config参数,这是来自system / libraries / Form_validation.php的构造函数:

public function __construct($rules = array())
