CodeIgniter - Mengupload File

Dengan menggunakan kelas Mengupload File, kita dapat mengupload file dan kita juga dapat membatasi jenis dan ukuran file yang akan diupload. Ikuti langkah-langkah yang ditunjukkan pada contoh yang diberikan untuk memahami proses pengunggahan file di CodeIgniter.

Contoh

Salin kode berikut dan simpan di application/view/Upload_form.php.

<html>
 
   <head> 
      <title>Upload Form</title> 
   </head>
	
   <body> 
      <?php echo $error;?> 
      <?php echo form_open_multipart('upload/do_upload');?> 
		
      <form action = "" method = "">
         <input type = "file" name = "userfile" size = "20" /> 
         <br /><br /> 
         <input type = "submit" value = "upload" /> 
      </form> 
		
   </body>
	
</html>

Salin kode yang diberikan di bawah ini dan simpan di application/view/Upload_success.php

<html>
 
   <head> 
      <title>Upload Form</title> 
   </head>
	
   <body>  
      <h3>Your file was successfully uploaded!</h3>  
		
      <ul> 
         <?phpforeach ($upload_data as $item => $value):?> 
         <li><?php echo $item;?>: <?php echo $value;?></li> 
         <?phpendforeach; ?>
      </ul>  
		
      <p><?php echo anchor('upload', 'Upload Another File!'); ?></p>  
   </body>
	
</html>

Salin kode yang diberikan di bawah ini dan simpan di application/controllers/Upload.php. Buat "uploadsFolder di root CodeIgniter, yaitu di direktori induk folder aplikasi.

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