我对CodeIgniter比较新，但我可以掌握一两件事。 我当前正面临一个问题，我希望管理员查看或下载用户注册时提交的上传文件（pdf和doc）。 一切都运作良好，但我希望管理员下载文件，而不仅仅是看到文件名。
这是我的控制器：
<?php
类NominationController扩展了CI_Controller {

parent::__construct();

这是我的View.php
<tr>

<td><?php echo $row['uniqueness'] ;?> </td>
</tr>
<tr>

<td><?php echo $row['supporting_documents'] ;?></td>
</tr>
以下是我输出的屏幕截图： I would like the pdf file or doc to be clickable
以下是我设置MySQL的方法：
..just in case its not set correctly
我感觉它的东西很小，但过去一周我的眼球疼痛了，我觉得谷歌知道我的名字，我现在在哪里睡觉:)
任何给予的帮助都会有很长的路要走。 谢谢
答案 0 :(得分：0)
根据文件： https://www.codeigniter.com/user_guide/helpers/url_helper.html#base_url
您可以像这样导入Url Helper：
$this->load->helper('url');
然后，您可以使用
<a href="<?= base_url('path/to/directory/' . $row['supporting_documents']); ?>"> Download </a>
方法base_url将返回您的站点基本URL，如配置文件中所指定。此外，参数将使用您提供的字符串连接该URL。这将是您文件的完整网址。
