上传功能

    function upload(){

     if(isset($_POST['userfile']) AND !empty($_POST['userfile']))

表单代码

<?php 
    echo form_open('/Home/upload');
?>
                    <br><div class="form-group"><input class ='form-control' placeholder="<?php echo lang('fileu'); ?>" type="file" name="userfile" size="20" /></div>

    <div class="alert alert-info"><?php echo lang('filetext'); ?></div>


  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-default" data-dismiss="modal"><?php echo lang('Close'); ?></button>
    <button type="submit" class="btn btn-primary"><?php echo lang('uploadsub'); ?></button>
    <?php echo form_close(); ?>

【问题讨论】：

还在文件名属性中提及您的文件扩展名

标签： php codeigniter upload

【解决方案1】：

您必须使用以下代码上传文件。您的表单中缺少 multipart 属性。

echo form_open_multipart('/Home/upload');

【讨论】：

【解决方案2】：

首先将您的辅助函数更改为form_open_multipart()。如果改用正确的函数后仍然报错，也可能是你的 maxsize 属性。如果上传的文件大于允许的大小，则 FILES 变量将为空。

尝试改变...

$config['max_size']       = '1000';

...类似于...

 $config['max_size']       = '30000';
