从模型到控制器并返回到模型的数据

<?php //controller
function notif()
{
    $condition = $this->business_model->get_condition();
    $this->data['query'] = $this->business_model->data_pagination_admin($condition);
        $this->load->view('student_result',$this->data);
}
?>

<?php //model
function get_condition()
{

  $this->db->select('condition');
  $this->db->from('staff');
  $query = $this->db->get(); 
  return $query->result_array();
}

function data_pagination_admin($condition)//notif function
{
    //...........
    $this->db->where('flag','n');
    //$user_id = $this->session->userdata('condition');
    $this->db->where($condition,$user);//notice parameter condition
    $this->db->order_by('next_date','asc');
    $query = $this->db->get('student',10,0);
    return $query->result_array();
}

 /*im getting error :"Unknown column '0' in 'where clause'

SELECT * FROM (`student`) JOIN `status_table` ON `student`.`stud_id` = 
   `status_table`.`stud_id` WHERE `status_table`.`next_date` > '2013-06-09 23:59:59'
 AND     `flag` = 'n' AND **`0` = Array ORDER** BY `next_date` asc LIMIT 10"*/


?>

1.im geting value from model to controller and passing it to controller to another function but getting error.

1.从模型到控制器的最小值,并将其传递给控制器到另一个函数但是出错。

2.controller->get_condition->controller->data_pagination_admin()

3.the get condition function will return just a string thats all

3. get条件函数将返回一个全部字符串

get_conditioncurrently returns an array; try the code below:

get_conditioncurrently返回一个数组;试试下面的代码:

function get_condition()
{
$user = $this->session->userdata('user_id');
$this->db->select('condition');
$this->db->from('staff');
$this->db->where('user_id',$user );
$query = $this->db->get(); 
$result = $query->row_array();
return $result['condition'];
}

Edit: looks like your $user var in that where clause is also an array.

编辑:看起来像$ user var,其中where子句也是一个数组。
