问题描述

嘿家伙得到错误未定义的变量见图片 http://imgur.com/oJMbrYo p>

我想做的是上传一个图像，然后将其发送到数据库的url。
这里是我的

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 - > session-> userdata（'uid'））; 
 $ data ['uname'] = $ details [0]  - > firstname。 。 $ details [0]  - > lastname; 
 $ data ['uemail'] = $ details [0]  - >电子邮件; 
 $ 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）;

解决方案

> 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]  - >电子邮件; 
  

像下面 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]  - >电子邮件; 
 $ data ['upload_data'] = $ this-> upload-> data（）; 
 $ data ['uid'] = $ this-> session-> userdata（'uid'）
 
 $ this-> load-& $ data）; 
  

因此，现在 do_upload（） ：

  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]  - >电子邮件; 
 
 if（！$ this-> upload-> do_upload（'userfile'））
 {
 $ data ['error'] = $ this->上传 - > display_errors（）; 
 $ this-> load-> view（'profile_view'，$ data）; 
} 
 else 
 {
 $ upload_data = $ this-> upload-> data（）; 
 $ images_name = $ upload_data ['file_name']; 
 //更新用户照片介绍数据库
 $ 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）; 
} 
}

Please let me know whats wrong with my code. Thanks.

Update Model

<?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 update($uemail,  $id) {


            $this->db->where('id', $id);
            $this->db->set('email', $uemail);
            $this->db->update('user');

    }

        $this->db->set('image', $uimage);
        $this->db->update('user');
    }
}


?>

解决方案

Also put bellow user information in do_upload method :

$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;

Like bellow do_upload method :

$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);

So, now do_upload() method is :

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);
    }
}
