我设置了提交脚本,人们可以在其中提交详细信息并上传附件。它全部记录在名为Submissions
的表中的数据库中,其中包含以下字段:fname
,lname
,snumber
和upload
。
upload
字段当前是服务器上文件的位置,例如,一个条目显示uploads/123456.zip
(上传是目录,123456.zip是文件名)。
我还有一个后端管理系统,其中显示所有提交。用于此的代码如下:
<html>

此代码完美无缺,但在上传字段下显示upload / 123456.ppt。如何让它显示http://sitename.com/uploads/123456.ppt并使其成为该文件的超链接?

只需将输出包装在<a>
标记
<td><font face="Arial, Helvetica, sans-serif"><a href="http://sitename.com/<?php echo $f5; ?>"><?php echo $f5; ?></a></font></td>

以下内容将打印包含固定网址的链接。
<?php
$url = 'http://www.' . $_SERVER['SERVER_NAME'] . '/' . $f1;
echo '<a href="' . $url . '">Click here to download the file!</a>';
如果$ _SERVER ['SERVER_NAME']不适合您的网站,您可以使用正确的域名替换它。
