使用crud将图像上传到codeigniter错误
[英]Image upload to codeigniter error using crud
问题描述
嘿家伙我得到一个错误未定义的变量见图http://imgur.com/oJMbrYo
我想要做的是上传一个图像，然后将其发送到数据库。 这是我的
档案控制器：
<?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'));
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';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile'))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('profile_view', $error);
}
else
{
$data = array('upload_data' => $this->upload->data(), $this->session->userdata('uid'));
$this->load->view('profile_view', $data);
}
}
`}
这是我的个人资料视图：

请告诉我我的代码有什么问题。 谢谢。
更新模型

class user_model extends CI_Model

另请在do_upload方法中do_upload用户信息：
$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;
像bellow do_upload方法：
$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;
$data['upload_data'] = $this->upload->data();
$data['uid'] = $this->session->userdata('uid')
$this->load->view('profile_view', $data);
所以，现在do_upload()方法是：
public function do_upload() {
$config['upload_path'] = './assets/img';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
$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;
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'));
$data['upload_data'] = $upload_data;
$data['uid'] = $this->session->userdata('uid')
$this->load->view('profile_view', $data);
}
}
