How to upload file in CodeIgniter framework

In this example we are going to show you how to how to upload file in CodeIgniter framework.

Here we using 3 files for upload file in CodeIgniter:
  • Upload.php Path: codeIgniter\application\controllers\Upload.php
  • upload_form Path: codeIgniter\application\views\upload_form.php
Create a folder uploads under your project folder.

Upload.php (Controller)

<?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'] = 1024; 
$config['max_width'] = 1024; 
$config['max_height'] = 1200; 
$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());
echo "File uploaded Successfully!"; } 
} 
} 
?>

upload_form.php (View)

<!DOCTYPE html>
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<h3>Your file was successfully uploaded!</h3>
<ul>
<?php foreach ($upload_data as $item => $value):?>
<li><?php echo $item;?>: <?php echo $value;?></li>
<?php endforeach; ?>
</ul>
<p><?php echo anchor('upload', 'Upload Another File!'); ?></p>
</body>
</html>
Run the program on your browser with URL:
http://localhost/codeIgniter/index.php/codeIgniter/upload
Here codeIgniter is my folder name. Put your folder name instead of codeIgniter.Rest of things are same.
