表格代碼

<?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>
  <div class="modal-footer">

    <button type="submit" class="btn btn-primary"><?php echo lang('uploadsub'); ?></button>
    <?php echo form_close(); ?>

Answer 1

您必須使用以下代碼上傳文件。 您缺少窗體中的multipart屬性。

echo form_open_multipart('/Home/upload');

Answer 2

首先將您的輔助函數更改為form_open_multipart() 。 如果更改為正確的函數后仍然出現錯誤，則它也可能是您的maxsize屬性。如果上載的文件大於允許的大小，則FILES變量將為空。

嘗試改變...

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

...像...

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