因为这个，我把头撞到墙上
我知道这是一个很长的问题，但这就是我所拥有的:(
我与 CI 合作一年多，但这个错误让我很生气问题是我从模型中获取数据，所以它返回
Unknown column 'albums' in 'where clause'</p><p>SELECT *
FROM (`albums`)
WHERE `id` = '1'
AND `albums` IS NULL
AND `id` = '1'
模型函数为
function get($id = 0 )
{
if($id == 0 )
{
$q = $this->db->get('albums')->result();
return $q;
}
else
{
$this->db->where("id",$id);
$q = $this->db->get('albums');
return $q->row();
}
}
如果我删除了对函数的调用，当我调试 $data 时，我会从 json_encode 收到另一个错误，我会得到以下信息

get上面的代码在另一个控制器中运行良好，如果我从视图中调用，模型的调用不会出现任何错误
我在此之前调用更新，它也不会更新
function update($id,$title,$description,$path)
{
$this->db->where('id',$id);
$this->db->set('title',$title);
$this->db->set('description',$description);
if($path != 'none')
$this->db->set('path',$path);
$q1 = $this->db->where('albums');
return $q1;
}
这是控制器方法
public function update2($action = "show",$id = 0 ,$row = 0 )
{
$data = array();
if($action == "show"):
$data['id'] = $id;
$data['row_number'] = $row;
$this->load->view('albums/edit_album',$data);
else:
$id = $this->input->post('id');
$title = $this->input->post('title');
$description = $this->input->post('description');
$path = $this->session->userdata('image_name_album');
$this->form_validation->set_rules('title', 'Title', 'trim|required|xss_clean');
$this->form_validation->set_rules('description', 'Description', 'trim|required|xss_clean');
if ($this->form_validation->run() == FALSE):
$errors = array();
$errors = $this->form_validation->errors_array();
$data['errors'] = $errors;
$data['response'] = "Errors";
echo json_encode($data);
die();
else:
//update($id,$author,$title,$albums,$short,$lang,$status)
$data['response'] = $this->albums_model->update($id,$title,$description,$path);;
$data['query'] = $this->albums_model->get($id);
print_r($data);
echo json_encode($data);
die();
endif;
endif;
}
