Codeigniter：以html格式显示数据库字段，然后编辑的表单字段在php脚本中不可见

问题描述：

I'm having little problem, I'll try to describe what is it about: at first page I got only form input field (username expected), then on submit I'm proceed to second page where I got form with fields that I've read from database and put them inside input value="xxx". When i retype some of that fields, and submit on next script form parameters are empty($field) == true. Fields are not empty and when I submit they are marked as empty variables.

Here's my code hope it will help:

My second page view (CODE)
My controller's method to take parameters from second page view (CODE)

Here's screenshots maybe it can be helpful:

Thanks in advance

我没有什么问题，我会尝试描述它是什么：在第一页我只得到了表单输入字段（用户名预期），然后提交我进入第二页，我得到表单，其中包含我从数据库中读取的字段，并将它们放在输入value =“xxx” code>中。当我重新键入其中一些字段，并在下一个脚本表单上提交参数时，为空（$ field）== true code>。字段不为空，当我提交时，它们被标记为空变量。 p>

这是我的代码希望它有所帮助： p>

I'm honestly sorry, I've just realized that in mixing that php and html, I've forgot to add name attribute in html tags.

You should pass a data array to the db. Something like this

    public function submitEditChanges($id){
    $data = array(
                'name' => $this->input->post('name'),
                'surname' => $this->input->post('surname'),
                'city' => $this->input->post('city'),
                'email' => $this->input->post('email'),
                'username' => $this->input->post('username'),
                'password' => sha1($this->input->post('password')),
                'passconf' => sha1($this->input->post('passconf'))
            );
            $this->db->where('id', $id);
            $this->db->update('users',$data);
    }
