1.im 从模型获取值到控制器并将其传递给控制器​​到另一个函数，但出现错误。

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

3.get 条件函数将只返回一个字符串，仅此而已

get_condition当前返回一个数组；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'];
}

编辑：看起来你在 where 子句中的 $user var 也是一个数组。

您可以使用var_dump()来查看某些变量和结果的值是什么。您不应该使用$query->row()它，因为它只会返回 1 行。我建议你应该像这样迭代数组：

foreach($query->result() as $result)
    {
    $this->data['query'].=$result
    }
