控制器

 <?php
        if (!defined('BASEPATH'))
            exit('No direct script access allowed');
        class Upload_Controller extends CI_Controller
        {
            public function __construct()
            {
                parent::__construct();
            }
            public function index(){
                $this->load->view('file_view', array(
                    'error' => ' '
                ));
            }
            public function file_view()
            {
                $this->load->view('file_view', array(
                    'error' => ' '
                ));
            }
            public function do_upload()
            {
                $config = array(
                    'upload_path' => "./uploads/",
                    'allowed_types' => "gif|jpg|png|jpeg|pdf",
                    'overwrite' => TRUE,
                    'max_size' => "2048000", // Can be set to particular file size , here it is 2 MB(2048 Kb)
                    'max_height' => "768",
                    'max_width' => "1024"
                );
                $this->load->library('upload', $config);
                if ($this->upload->do_upload()) {
                    $data = array(
                        'upload_data' => $this->upload->data()
                    );
                    $this->load->view('upload_success', $data);
                } else {
                    $error = array(
                        'error' => $this->upload->display_errors()
                    );
                    $this->load->view('file_view', $error);
                }
            }
        }
        ?>

File_view

<?php echo $error;?>
<!-- Error Message will show up here -->
<?php echo form_open_multipart( 'upload_controller/do_upload');?>
<?php echo "<input type='file' name='userfile' size='20' />"; ?>
<?php echo "<input type='submit' name='submit' value='upload' /> ";?>
<?php echo "</form>"?>

upload_success

<h3>Your file was successfully uploaded!</h3>
    <!-- Uploaded file specification will show up here -->
    <ul>
        <?php foreach ($upload_data as $item => $value):?>
            <li>
                <?php echo $item;?>:
                    <?php echo $value;?>

            </li>
            <?php endforeach; ?>
    </ul>
    <p>
        <?php echo anchor('upload_controller/file_view', 'Upload Another File!'); ?>
    </p>

Answer 3

只需执行此操作即可查看文件

<h3>Your file was successfully uploaded!</h3>
<img src="<?php echo upload_data['full_path']; ?>">
<?php echo anchor('upload_controller/file_view', 'Upload Another File!'); ?>

希望这对你有帮助。
