请帮助我，我无法访问我的代码，它总是显示错误：
遇到未捕获的异常

这是代码：

INGallery.php更改此行
public function edit($id_gallery){
...
$this->Gallery_model->edit($data);
...
}
自
public function edit($id_gallery){
...
$this->Gallery_model->edit($id_gallery, $data);
...
}
这是因为该方法(在Gallery_model中(定义为：
public function edit($id_gallery, $data){ ... }
这需要库 ID 和数据。您只向它发送了数据...
选项 2
似乎ID是数据的一部分的另一种选择是删除Gallery_model中的第一个参数。所以它看起来像这样：
// Edit
public function edit($data){
$this->db->where('id_gallery', $data['id_gallery']);
$this->db->update('gallery', $data['id_gallery']); //see below
}
该错误有点令人困惑，但它可能来自在"图库"控制器中调用此方法的位置。
最后
最后一件事是这可能是错误的：
$this->db->update('gallery', $data['id_gallery']);
我不怎么使用 CI，但似乎如果您正在进行更新，您将需要更多的数据，而不仅仅是画廊的 ID。 这完全有可能应该是：
$this->db->update('gallery', $data);
但正如我所说，这些天我不太使用CI，所以我不能肯定地说。 但这似乎更有意义：
// Edit
public function edit($id_gallery, $data){
$this->db->where('id_gallery', $id_gallery);
$this->db->update('gallery', $data);
}
//and call it this way $this->Gallery_model->edit($id_gallery, $data);
无论如何，希望它有所帮助
干杯！
