interacting with the filesystem

[daniela]

I am planning to store some pdf articles on the filesystem and access the files via php code. Ive managed to upload some txt files to the filesystem and display the file names with a link once they are uploaded.
The problem is when I click on a link a 'page cannot be found' error appears.

Okay, so I can upload files to /tmp/uploads/

I've got a readdirectory.php script in the public html directory /www/articles_files/

When I run the script it displays the /tmp/uploads/ directory and lists the files as links but when I click on a link it trys to access the file from the public html diresctory /www/articles_files/file.txt when it's really stored in /tmp/uploads/file.txt

How do I stop this happening?

I've tried naming the entire path i.e. /home/user/tmp/uploads but I just get an error message saying the directory doesn't exist.

I'm going crazy trying to figure this out.

your server cant access the /tmp/uploads/ directory.
simply upload files in /www/articles_files and fix your script to display files from /www/articles_files/

u've to make your links like this

<a href="link.php?file=file.txt">file.txt</a>

so when user clicks this link your script will do something like this:

$tmp_dir = '/tmp/uploads/';

$file_name = is_set($_GET['file'])?$_GET['file']:'';

if(!$file_name) {exit;}

$filename = $tmp_dir.$file_name;

    header("Cache-control: private");
    header("Content-type: application/force-download");
    header("Content-Length: ".filesize($filename));
    header("Content-Disposition: filename=".$file_name);

    readfile($filename);

So what you are trying to do is a directory lister right?

I've tried the suggested solutions here but nothing has worked.


This is how I made the dir:

<?

if (mkdir ("/pdfs/", 0777
))
{
echo "Successful!";
}
else
{
echo "Unsuccessful";
}
?>


This is the upload script

<?

// get some information
echo "Filename: $upfile_name<br>";
echo "Temporary filename: $upfile<br>";
echo "File size: $upfile_size bytes<br>";
echo "File type: $upfile_type<br>";

// if upload successful
if ($upfile)
{
echo "Upload successful!<br>";
// copy file to new location
if (copy("$upfile", "/tmp/pdfs/" . $upfile_name))
{
echo "File copy successful!<br>";
}
}
// else display error
else
{
echo "Upload unsuccessful!<br>";
}
?>

<?

if ($upfile_type == "text/plain" || $upfile_type == "text/html" ||
$upfile_type == "image/gif" || $upfile_type == "text/php")
{
// file upload code
}
else
{
echo "Permission denied!";
}
?>

This is the read directory script:


<?

$tmp_dir = ("/tmp/pdfs/");

// get directory handle
$hook = opendir("/tmp/pdfs/");

// read directory and echo list
while (readdir($hook))
{
$file = readdir($hook);

echo ('<a href="'.$tmp_dir.$file.'">'.$file."</a><br>");

}

// close directory
closedir($hook);
?>

can ayone see what I've done wrong?

[eugeneasm]

here is an error.

echo ('<a href="'.$tmp_dir.$file.'">'.$file."</a><br>"); 

you browser knows nothing about the '/tmp' directory on your server.

u've to let some other script to serve file download.

so u need to do something like this

echo ('<a href=output.php?file="'.$tmp_dir.$file.'">'.$file."</a><br>"); 

and the output.php will have to do the following actions [check for errors plz]:

[output.php]

<?

$file = $_GET['file'];

$ar = array();

$ar = file($file);

$content = join("\n",$ar);

print $content;

?>

this has to work with all textual files..
