PHP File reference

I have created an upload page that admin users can upload files to. I then created viewing page that end users can download files from. File types will be MS Excel files. This is working if I go directly to the directory URL I can see and link to the file and windows opens up the file and asigns EXCEL to open it up ....... all is good
What I need is a script of some sort that will display the file path or a link to the file in my viewing page. I need this to be automated in that for every file loaded the old file is deleted and the link is updated.
I am so stumped. Please help even if you can only show me the file <a href=""> side of things just need it to look in my directory for the file and show me a link.

Code: Select all
if ($handle = opendir('.'))
{
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
echo "$file<br/>";
}
}
closedir($handle);
}
For
future reference, the PHP
manual is a wonderful repository of information for tasks like this.

Thank you very much I had something similar but yours works better however what I need is for the result "$file" to show as a hyper link to the actual file itself. I want to enable my end users to click on the link and open up that particular file (MS Excel File)
I have tried using <a href=" "></a> and it doesn't work.Without the <a href=""> statement it works fine but the result is not a hyperlink, it is just a string of text.
Do you have any other suggestions? Thanks again for your help.

$file holds each URL as it loops through the folder, so just adapt the $file for your link.

Wow that was awesome I almost have it. There is one snag. When I used your code this is what my code looks like:
<?php
if ($handle = opendir ('/update/upload1')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "<a href=$file>$file</a></br>";
}
}
closedir($handle);
}
?>
The one snag is that the URL returns and completely skips over a directory so when you click on the link it does not make it to the file.
the returned URL: http://www.--------.com/update/testdoc.doc
The actual file URL is http://www.-------.com/update/upload1/testdoc.doc
Can you tell me where I am screwing up here? Thanks you have been of great help, and props on the great explanation.

Specify your directory path in a variable so that you can reference it again later, since $handle is going to become a directory resource. So your scripts ends up looking like.....
Code: Select all
//place your path in $path
$path = '/update/upload1/';
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
//attach our path to the filename for our url
$filelist .= '<a href="'.$path.$file.'">'.$file.'</a><br/>';
}
}
closedir($handle);
}
//place this anywhere to display the list
echo $filelist;
