Hochladen von Bild in db mit Codeigniter 3.0.1

Question

Ich habe viele Formulare/Antwort gelesen hatte mir nicht sehr geholfen CI 3.0 +. Versuch, den Bildpfad in die MySQL-Datenbank hochzuladen. Es scheint, als ob meine Update-Abfrage nicht funktioniert (die Image-Spalte hat vor dem Ausführen der Abfrage nichts). Hier ist mein Controller, die das Upload-Dingen Bei der Verarbeitung:

i genommen habe es von CI Dokumentation upload.php

<?php 

class Upload extends CI_Controller { 

    public function __construct() 
    { 
      parent::__construct(); 
      // $this->load->helper(array('form', 'url')); 
      $this->load->library('upload'); 
    } 

    public function index() 
    { 
      $this->load->view('layouts/header'); 
      $this->load->view('home_page', array('error' => ' ')); 
      $this->load->view('layouts/footer'); 
    } 

    public function do_upload() 
    { 

      $config['upload_path']   = './uploads/'; #$this->config->item('base_url'). 
      $config['allowed_types']  = 'gif|jpg|png|jpeg'; 
      // $config['max_size']    = 100; 
      // $config['max_width']   = 1024; 
      // $config['max_height']   = 768; 

      // $this->load->library('upload', $config); 

      $this->upload->initialize($config); 

      if (! $this->upload->do_upload('userfile')) 
      { 
        $error = array('error' => $this->upload->display_errors('<p>','</p>')); 

        $this->load->view('layouts/header'); 
        $this->load->view('home_page', $error); 
        $this->load->view('layouts/footer'); 
      } 

      else 
      { 

        $this->load->model('model_edit'); 
        $id = $this->session->userdata('id'); 
        $data = array('upload_data' => $this->upload->data()); 
        $image['img'] = $this->upload->data('file_name'); 


        $this->model_edit->update_dp($id, $data); 

        #base_url().'upload/'. 

        $this->load->view('layouts/header'); 
        // echo $id; 
        $this->load->view('home_page', $image); 
        $this->load->view('layouts/footer'); 
      } 
    } 
    } 
    ?> 

dies ist meine Modellklasse model_edit.php

<?php 

class Model_edit extends CI_Model 
{ 

public function __construct() 
{ 
    parent::__construct(); 
} 
public function update_dp($id, $data) { 

    $image_path = $this->upload->data('file_path'); 
    $sql = "UPDATE users SET images = '{$image_path}' WHERE id = '{$id}' LIMIT 1"; 
    $result = $this->db->query($sql); 
    $row = $this->db->affected_rows(); 

    if ($row) { 
     return $image_path; 
    } 
    else 
    return FALSE;  
} 
} 
?> 

Dieses ist die Ansicht, die ich verwende home_page.php

<?php 
$session_data = $this->session->userdata('logged_in'); 
$check = $this->session->userdata('remember_me'); 

?> 
<div class="container"> 
<div class="row"> 
    <?php include('navbar.php'); ?> 
</div> 
<div class="row"> 
    <div class="col-xs-10"> 
     <?php 

      if ($check) 
      {?> 
      <div class="row"> 
       <div class="col-xs-4 col-xs-3"> 
       <?php if (isset($upload_data)) 
       { 
       echo "Successfully Uploaded DP"; 
       echo $img; 
       ?> 
       <img src="<?php echo $img; ?>"/> 
       <?php 
       }?>    
       <?php if(isset($error))echo $error; echo form_open_multipart('upload/do_upload');?> 

       <input type="file" name="userfile"/> 
       <br /> 
       <input type="submit" name="submit" value="upload" /> 

       </form> 
       <hr> 
       </div> 
       <div class="col-xs-6 col-xs-5"> 

       </div> 
      </div> 
      <div class="row"> 
       <div class="col-xs-4 col-xs-3"> 
       <label class="text-center"> User Information </label><a href="edit"><span class="glyphicon glyphicon-pencil pull-right"></span></a> 
       <br><br> 
       <label>Email: </label> 
       <br> 
       <?php echo $session_data['email'];?> 
       <br><br> 
       <label>Display Name: </label> 
       <br> 
       <?php echo $session_data['name'];?> 
       <br><br> 
       <label>Username: </label> 
       <br> 
       <?php echo $session_data['username'];?> 
       <br><br> 
       <a href="logout">Logout</a> 
       </div> 
      </div> 

      <?php 

      } 
      else 
      { 
       // session_set_cookie_params(0); 
       include('browser_triger.php'); 
       $session_data['username']; 
       $session_data['name']; 
       $session_data['email']; 
      } 
     ?> 
    </div> 
</div>

Sie benötigen Bildpfad in der Steuerung zu erhalten und nur Bildnamen übergeben Datei

$image_path = $this->upload->data('file_name'); 
$this->model_edit->update_dp($id, $file_name);// pass image name 

In Models

function update_dp($id, $file_name) { 
    $this->db->set("images", $file_name); 
    $this->db->where("id", $id); 
    $this->db->update("users"); 
    $row = $this->db->affected_rows(); 

    if ($row) { 
     return $image_path; 
    } else{ 
     return FALSE; 
    } 
} 

In Controller zu modellieren
