这是我的查看页面表单HTML代码：

欢迎消息.php

<div class="form-group">
    <input type="file" name="profile_name" > 
</div>

 public function do_upload() {
     $config['upload_path'] = './uploads/';
     $config['allowed_types'] = 'doc|xml|docx|PDF|DOC|XML|DOCX|xls|xlsx';
     $config['max_size'] = 100;
     $config['max_width'] = 1024;
     $config['max_height'] = 768;

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

     if (!$this - > Welcome - > do_upload('profile_name')) {
         $error = array('error' => $this - > upload - > display_errors());

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

         $this - > load - > view('upload_success', $data);
         //echo "Your file was successfully uploaded!";
     }
 }

<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>

这是成功函数代码：upload_success.php

<div class="form-group">
    <input type="file" name="profile_name" > 
</div>

 public function do_upload() {
     $config['upload_path'] = './uploads/';
     $config['allowed_types'] = 'doc|xml|docx|PDF|DOC|XML|DOCX|xls|xlsx';
     $config['max_size'] = 100;
     $config['max_width'] = 1024;
     $config['max_height'] = 768;

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

     if (!$this - > Welcome - > do_upload('profile_name')) {
         $error = array('error' => $this - > upload - > display_errors());

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

         $this - > load - > view('upload_success', $data);
         //echo "Your file was successfully uploaded!";
     }
 }

<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>

检查这是否有助于您，加载库后初始化上载配置。

这是我的代码，没有显示错误消息，也没有上载文件。请任何人帮助我。
