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(); ?>

Answer 1

您必须使用以下代码上传文件。您在表单中缺少multipart属性。

echo form_open_multipart('/Home/upload');

Answer 2

首先将助手功能更改为form_open_multipart()。如果在更改为正确的函数后仍然出现错误，则它也可能是您的maxsize属性。如果上载的文件大于允许的大小，则FILES变量将为空。

尝试更改......

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

......类似......

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

php.net File Upload

您没有选择要上传CodeIgniter的文件
