how to dynamically link uploaded documents?

edkuan

hi
i've created a basic upload function where user can upload documents to 'upload' folder .

the problem now is
1) how to display the list of documents uploaded in the 'upload' folder and

2) to link the list to the documents so user be able to open that document(or download it).

this is the form.php used to upload :

this is the upload.php used to upload :

<?php
// ==============
// Configuration
// ==============
$uploaddir = "uploads"; // Where you want the files to upload to - Important: Make sure this folders permissions is 0777!
// ==============
// Upload Part
// ==============
if(is_uploaded_file($FILES['file']['tmp_name']))
{
move_uploaded_file($FILES['file']['tmp_name'],$uploaddir.'/'.$_FILES['file']['name']);
}
print "Your file has been uploaded successfully! Yay!";
?>

I hope you guys could help

fyi i am using dmx /php/mysql

thanks

you can get a file list using scan_dir() from your upload directory and then output the filenames as links to download.

ok thanks

i've used this :

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
</head>

</body>
</html>

but got this error msg :

Fatal error: Call to undefined function: scandir() in c:\apache\htdocs\online training support system\tmpabcut6unox.php on line 10

why does this happen ?

Copied from: http://us2.php.net/manual/en/function.opendir.php

$dir = "/etc/php5/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
   if ($dh = opendir($dir)) {
       while (($file = readdir($dh)) !== false) {
           echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
       }
       closedir($dh);
   }
}

How do you mean dynamically linking them?

Like, make links on your page to them?

If so, then you need to make sure your image folder is publicly accessible, and just use the code to write links. If you don't want to do it that way, then set up a wrapper image script that uses fpassthru() or similar.

ok through trial eror i made up this code

<?php
if ($handle = opendir('C:\apache\htdocs\Upload documents\documents'))
{
while (false !== ($file = readdir($handle)))
{

echo "<a href='$file'>$file</a> <br /> \n";
}
closedir($handle);
}
?>

out put :

documents_A.php
documents_B.php
documents_C.php
sample.doc

this is what i wanted , but the weird thing is sometimes some of the links produces error - internal server error

why does this happen?

zabmilenko , what do u mean make the folder public accessible ? my last reply above , the link only works if the page or doucments is in the root folder but not in the sub folder... wonder why?
Upload documents= root folder
upload documents=sub folder
