Question

我想在我的网站上显示用户的更新个人资料页面。数据库上的更新实际上正在工作，但我希望我的userprofile页面在单击提交按钮后显示更新的数据。我将在这里添加什么D：

Answer 1

重定向应为

redirect('MemberLoginController/members');
redirect('Controller/Method');

如果未添加方法，则默认情况下会调用index()方法

Answer 2

您应该将form_validation对象与您的代码结合使用。

public function update($id)
{
    if ( (int)$id < 1)//$id is not an integer
    {
        redirect('memberlogincontroller/home', 'refresh');
    }
    else
    {
        $this->load->library('form_validation');//it's good to autoload it

        $this->form_validation->set_rules('memberfname', 'First Name', 'trim|required');
        $this->form_validation->set_rules('memberlname', 'Last Name', 'trim|required');
        $this->form_validation->set_rules('email', 'Email', 'trim|required');

        if ($this->validation_form->run() === FALSE)
        {
            $this->load->view('userprofile');
        }
        else
        {
            $data = array(
                'memberfname' => $this->input->post('memberfname'),
                'memberlname' => $this->input->post('memberlname'),
                'email' => $this->input->post('email'),
            );

            $this->db->update('member',$data,array('id'=> $id));
            redirect('memberlogincontroller/getMember/' . $id, 'refresh');
        }

    }
}

在模型中，您没有传递特定成员的ID。它应该是这样的

public function getMember($id)
{
    $this->db->where('id', $id);
    $query = $this->db->get('member');

    if ($query->num_rows() !== 1)
    {
        return FALSE;
    }
    return $query->row();//since you need just single member data
}

此外，在控制器方法代码中，您必须将$id传递给model：

public function getMember($id)
{
    if (int($id) < 1)
    {
        redirect('memberlogincontroller/home', 'refresh');//no valid uri segment
    }
    else
    {
        $this->load->model('MemberLoginModel');
        $memberinfo['memberinfo'] = $this->MemberLoginModel->getMember($id);

        if ( ! $memberinfo['memberinfo'])//returned FALSE from model
        {
            redirect('memberlogincontroller/home', 'refresh');//no $id in DB
        }
        else
        {
            $this->load->view('member/userprofile',$memberinfo);
        }
    }
}

另外，您应该注意命名约定。你不应该关闭文件与关闭php标签。我的建议是仔细阅读docs，因为你可以避免许多烦人的错误。
