Wie die hochgeladene Dateinamen von upload.php Seite Codeigniter

Question

zu bekommen habe ich upload.php Seite wie folgt =>

<?php 

    class Upload extends CI_Controller { 

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

     public function index() { 
     $this->load->view('upload_form', array('error' => ' ')); 
     } 

     public function do_upload() { 
     $config['upload_path'] = './uploads/'; 
     $config['allowed_types'] = 'gif|jpg|png|pgn'; 
     $config['max_size']  = 0; 
     //$config['max_width']  = 1024; 
     //$config['max_height'] = 768; 
      $config['detect_mime'] = TRUE; 
     $this->load->library('upload', $config); 

     if (! $this->upload->do_upload('userfile')) { 
      $error = array('error' => $this->upload->display_errors()); 
      $this->load->view('upload_form', $error); 
     } 

     else { 
      $data = array('upload_data' => $this->upload->data()); 
      $this->load->view('upload_success', $data); 
     } 
     } 
    } 
?> 

und die Hesaplama.php Controller als =>

$upload_data = $this->upload->data(); //(line 51) Should return array of containing all of the data related to the file you uploaded. 
    $file_name = $upload_data['file_name']; 
    $file = fopen("<?php echo site_url('uploads/$file_name'); ?>", "r"); 

    while(! feof($file)) 
     {... 

aber ich Erhalten Sie den folgenden Fehler =>

A PHP Error was encountered 

Severity: Notice 

Message: Undefined property: Hesaplama::$upload

Line Number: 51 

Backtrace:

Wie können wir das beheben und den Dateinamen der neu hochgeladenen Datei abrufen? Ich persönlich denke, dass das Programm die Daten auf einer anderen Seite (Controller) nicht erkennt. Danke ...

Answer 1

Sorry ich kann noch nicht kommentieren, also schreibe ich es hier. Ich denke, die Bibliothek für

$this->upload->data(); 

wurde nicht geladen.

Wenn Sie nur den Dateinamen abrufen möchten, können Sie vielleicht versuchen, Sitzung zu verwenden. in hochladen Controller:

$data = $this->upload->data(); 
$this->session->set_userdata('filename', $data['file_name']); 

in Hesaplama:

$filename = 'uploads/'.$this->session->userdata('filename'); 
$file = fopen("<?php echo site_url('$filename'); ?>", "r"); 

hoffen, dass diese Hilfe.

Answer 2

den Dateinamen und Erweiterung Datei, um es in einem DB zu speichern tis

<?php 

    class Upload extends CI_Controller { 

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

     public function index() { 
     $this->load->view('upload_form', array('error' => ' ')); 
     } 

     public function do_upload() { 
     $config['upload_path']  = './uploads/'; 
     $config['allowed_types'] = 'gif|jpg|png|pgn'; 
     $config['max_size']  = 0; 
     $config['detect_mime'] = TRUE; 

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

     if(! $this->upload->do_upload('userfile')) { 
      $error = array('error' => $this->upload->display_errors()); 
      $this->load->view('upload_form', $error); 
     } 
     else { 
      $upload_data = $this->upload->data(); 

      /* 
      Array 
      (
        [file_name] => mypic.jpg 
        [file_type] => image/jpeg 
        [file_path] => /path/to/your/upload/ 
        [full_path] => /path/to/your/upload/jpg.jpg 
        [raw_name]  => mypic 
        [orig_name] => mypic.jpg 
        [client_name] => mypic.jpg 
        [file_ext]  => .jpg 
        [file_size] => 22.2 
        [is_image]  => 1 
        [image_width] => 800 
        [image_height] => 600 
        [image_type] => jpeg 
        [image_size_str] => width="800" height="200" 
      ) 
      */ 

      $this->model->save_img_info($upload_data['file_name']); 

      $data = array('upload_data' => $upload_data); 
      $this->load->view('upload_success', $data); 
     } 
     } 
    } 
?>
