这是我的个人资料控制器：
<?php
class Profile extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper(array('url', 'html', 'form'));
$this->load->library(array('session', 'form_validation'));
$this->load->database();
$this->load->model('user_model');
}
function index()
{
$details = $this->user_model->get_user_by_id($this->session->userdata('uid'));
$data['uname'] = $details[0]->firstname . " " . $details[0]->lastname;
$data['uemail'] = $details[0]->email;
$this->load->view('profile_view', $data);
}
function delete()
{
$this->user_model->delete_row($this->session->userdata('uid'));
redirect('Site/index');
}
function update()
{
$this->user_model->update($this->input->post("name"), $this->session->userdata('uid'));
$this->user_model->update($this->input->post("email"), $this->session->userdata('uid'));
$this->user_model->add_image($this->input->post('userfile'), $this->session->userdata('uid'));
redirect('profile/index');
}
public function index1()
{
$this->load->view('profile_view', array('error' => ' '));
}
public function do_upload()
{
$config['upload_path'] = './assets/img';
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
$details = $this->user_model->get_user_by_id($this->session->userdata('uid'));

if (!$this->upload->do_upload('userfile')) {
$data['error'] = $this->upload->display_errors();
$this->load->view('profile_view', $data);
} else {
$upload_data = $this->upload->data();
$images_name = $upload_data['file_name'];
//update user photo intro database
$this->user_model->add_image($images_name, $this->session->userdata('uid'), $upload_data['file_name']);
$data['upload_data'] = $upload_data;
$data['uid'] = $this->session->userdata('uid');
$this->load->view('profile_view', $data);
}
}
}
这是我的用户模型：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class user_model extends CI_Model
{
function __construct()
{
parent::__construct();
}
function get_user($email, $password)
{
$this->db->where('email', $email);
$this->db->where('password', $password);
$query = $this->db->get('user');
/* Select * from users where email = $_Post['email'] and password = $_post['password'] */
return $query->result();
}
// get user
function get_user_by_id($id)
{
$this->db->where('id', $id);
//select id from users where id = $_Post['id']
$query = $this->db->get('user');
return $query->result();
}
// insert
function insert_user($data)
{
return $this->db->insert('user', $data);
}
//delete row
function delete_row($id)
{
$this->db->where('id', $id);
$this->db->delete('user');
}
function update($uemail, $id)
{
$this->db->where('id', $id);
$this->db->set('email', $uemail);
$this->db->update('user');
}
function add_image($uimage, $id){
$this->db->where('id', $id);
$this->db->set('image', $uimage);
$this->db->update('user');
}
}
?>

答案 0 :(得分：1)
它告诉你$upload_data['file_name']不存在。
我认为这是因为你没有上传任何内容，那么当你这样做时 - 它存在并且一切都很好。
所以，你可以换掉
<img alt="Your uploaded image" src="<?=base_url(). 'assets/img/' . $upload_data['file_name'];;?>">
有：
<?php if(isset( $upload_data['file_name'] )){ ?>
<img alt="Your uploaded image" src="<?=base_url(). 'assets/img/' . $upload_data['file_name'];?>">
<?php } ?>
在尝试应用之前检查是否已设置。

发现问题应该在配置文件控制器中修复它：）
function index()
{
if (!isset($details[0])){
$details = $this->user_model->get_user_by_id($this->session->userdata('uid'));
$data['uname'] = $details[0]->firstname . " " . $details[0]->lastname;
$data['uemail'] = $details[0]->email;
$this->load->view('profile_view', $data);}
