[Resolved] Creating and viewing directories based on session variable

[Aesop]

😃 Hello,

I am working on a function for a client login site and I am a bit confuzzed about how to go about making one of the most important features! Lemme give you the scenario

An employee here creates an account for his/her client (username, password included in this process) and upon submission of that form the account gets created. Their user and pass gets stored in a database called users. Add to it that a directory gets created based off of the clients username after the form is submitted (using mkdir) under a folder called usrfiles. So in essence, when that client logs in they can also see what is in their folder.

I am passing the following session variable all over this site so each users info stays confidential to their eyes only.

session_start();
header("Cache-control: private"); // IE 6 Fix.
$user_name = $_SESSION['user_name'];
require '../../globals/dbconnect.php';

'user_name' will be the same name as the clients user and folder the employee created.

1. Should the users table store some kind of value regarding this directory? If so, how and what?

2. On the page that displays the folder contents how would it connect to just that folder?

I have a script that works for displaying folder contents, but I can't figure out how to tell it to just look at one particular folder under this criteria

Heres the script

 
clearstatcache();
if ($handle = opendir('.')) {
  while (false !== ($file = readdir($handle))) { 
    if ($file != "." && $file != ".." && $file != substr($PHP_SELF, -(strlen($PHP_SELF) - strrpos($PHP_SELF, "/") - 1))) { 

  if (filetype($file) == "dir") {
	  //SET THE KEY ENABLING US TO SORT
	  $n++;
	  if($_REQUEST['sort']=="date") {
		$key = filemtime($file) . ".$n";
	  }
	  else {
		$key = $n;
	  }
      $dirs[$key] = $file . "/";
  }
  else {
	  //SET THE KEY ENABLING US TO SORT
	  $n++;
	  if($_REQUEST['sort']=="date") {
		$key = filemtime($file) . ".$n";
	  }
	  elseif($_REQUEST['sort']=="size") {
		$key = filesize($file) . ".$n";
	  }
	  else {
		$key = $n;
	  }
      $files[$key] = $file;
  }
}
  }
closedir($handle); 
}

#USE THE CORRECT ALGORITHM AND SORT OUR ARRAY
if($_REQUEST['sort']=="date") {
	@ksort($dirs, SORT_NUMERIC);
	@ksort($files, SORT_NUMERIC);
}
elseif($_REQUEST['sort']=="size") {
	@natcasesort($dirs); 
	@ksort($files, SORT_NUMERIC);
}
else {
	@natcasesort($dirs); 
	@natcasesort($files);
}

#ORDER ACCORDING TO ASCENDING OR DESCENDING AS REQUESTED
if($_REQUEST['order']=="desc" && $_REQUEST['sort']!="size") {$dirs = array_reverse($dirs);}
if($_REQUEST['order']=="desc") {$files = array_reverse($files);}
$dirs = @array_values($dirs); $files = @array_values($files);

echo "<table width=\"375\" border=\"0\" cellspacing=\"0\" align=\"left\"><td colspan=\"1\">";
if($_REQUEST['sort']!="name") {
  echo "<a href=\"".$_SERVER['PHP_SELF']."?sort=name&order=asc\">";
}
else {
  if($_REQUEST['order']=="desc") {#
    echo "<a href=\"".$_SERVER['PHP_SELF']."?sort=name&order=asc\">";
  }
  else {
    echo "<a href=\"".$_SERVER['PHP_SELF']."?sort=name&order=desc\">";

  }

  }
}

if($_REQUEST['sort']!="date") {

}

  }
  else {

  }
}
echo "Date Modified</a></td></tr>";

$arsize = sizeof($dirs);

  echo "\t\t<td width=\"120\" align=\"left\" nowrap>" . date ("M d Y h:i:s A", filemtime($dirs[$i])) . "</td>";
  echo "\t</tr>";
}

$arsize = sizeof($files);
for($i=0;$i<$arsize;$i++) {
  switch (substr($files[$i], -3)) {

  }
  echo "\t\t<td><a href=\"" . $files[$i] . "\">" . $files[$i] . "</a></td>\r\n";
  echo "\t\t<td width=\"50\" align=\"left\">" . round(filesize($files[$i])/1024) . "KB</td>\r\n";
  echo "\t\t<td width=\"120\" align=\"left\" nowrap>" . date ("M d Y h:i:s A", filemtime($files[$i])) . "</td>\r\n";
  echo "\t</tr>\r\n";
}
echo "</table>";

Suggestions from any of the great minds in here???? 😕

you could, and i probably would store the filepath to the users directory in the database.

you would then (as the user logs in) store this in a session variable. then, after looking at your code. i think, if you change this line;

if ($handle = opendir('.'))

to;

if ($handle = opendir($_session['user_dir']))

or easier still. you say the user directories are based on the user names... you could call that directory using.

if ($handle = opendir('/home/www/users/'.$_SESSION['user_name']))

you my friend.. you are the man!

Ok so I got it listing the contents. When I click on any of the contents it wont let me download or view. Upon inspection, its reading it that its not in that 'user_name' directory, rather its in the same directory that the current page I'm viewing that shows the directory listing. So in essence, it's showing the directory contents, but its not creating a true a href link to the file. 😕

I looked over the code, and I can't really spot where I can change this. Here's what I got

<?

clearstatcache();
if ($handle = opendir('../../usrfiles/'.$_SESSION['user_name'])) {
  while (false !== ($file = readdir($handle))) { 
    if ($file != "." && $file != ".." && $file != substr($PHP_SELF, -(strlen($PHP_SELF) - strrpos($PHP_SELF, "/") - 1))) { 

  if (filetype($file) == "dir") {
	  //SET THE KEY ENABLING US TO SORT
	  $n++;
	  if($_REQUEST['sort']=="date") {
		$key = filemtime($file) . ".$n";
	  }
	  else {
		$key = $n;
	  }
      $dirs[$key] = $file . "/";
  }
  else {
	  //SET THE KEY ENABLING US TO SORT
	  $n++;
	  if($_REQUEST['sort']=="date") {
		$key = filemtime($file) . ".$n";
	  }
	  elseif($_REQUEST['sort']=="size") {
		$key = filesize($file) . ".$n";
	  }
	  else {
		$key = $n;
	  }
      $files[$key] = $file;
  }
}
  }
closedir($handle); 
}

#USE THE CORRECT ALGORITHM AND SORT OUR ARRAY
if($_REQUEST['sort']=="date") {
	@ksort($dirs, SORT_NUMERIC);
	@ksort($files, SORT_NUMERIC);
}
elseif($_REQUEST['sort']=="size") {
	@natcasesort($dirs); 
	@ksort($files, SORT_NUMERIC);
}
else {
	@natcasesort($dirs); 
	@natcasesort($files);
}

#ORDER ACCORDING TO ASCENDING OR DESCENDING AS REQUESTED
if($_REQUEST['order']=="desc" && $_REQUEST['sort']!="size") {$dirs = array_reverse($dirs);}
if($_REQUEST['order']=="desc") {$files = array_reverse($files);}
$dirs = @array_values($dirs); $files = @array_values($files);

echo "<table width=\"375\" border=\"0\" cellspacing=\"0\" align=\"left\"><td colspan=\"1\">";
if($_REQUEST['sort']!="name") {
  echo "<a href=\"".$_SERVER['PHP_SELF']."?sort=name&order=asc\">";
}
else {
  if($_REQUEST['order']=="desc") {#

  }
}
echo "File</td><td width=\"50\"></a>";

  }
}
echo "Size</td><td width=\"120\" nowrap></a>";
if($_REQUEST['sort']!="date") {
  echo "<a href=\"".$_SERVER['PHP_SELF']."?sort=date&order=asc\">";
}
else {

  echo "\t</tr>";
}

$arsize = sizeof($files);
for($i=0;$i<$arsize;$i++) {
  switch (substr($files[$i], -3)) {

  }
  echo "\t\t<td><a href=\"" . $files[$i] . "\">" . $files[$i] . "</a></td>\r\n";
  echo "\t\t<td width=\"50\" align=\"left\">" . round(filesize($files[$i])/1024) . "KB</td>\r\n";
  echo "\t\t<td width=\"120\" align=\"left\" nowrap>" . date ("M d Y h:i:s A", filemtime($files[$i])) . "</td>\r\n";
  echo "\t</tr>\r\n";
}
echo "</table>";
?>

would this line be the source of the problem?

while (false !== ($file = readdir($handle)))

Wow what an adventure. I contacted the maker of the script and he was far from useful... So I googled around and found a different script which does the job with flying colors.

So I would like to share my findings 🙂

<?php
		  $user_name = $_SESSION['user_name'];
require '../../globals/dbconnect.php';
$temp        =    getenv( "QUERY_STRING");
$dir_name    =    "$temp";

if($dir_name == "") $dir_name = "../../usrfiles/".$_SESSION['user_name']."";
$handle=opendir($dir_name);

while ($file = readdir($handle)) {
  $filelst = "$filelst,$file";
}
closedir($handle);
$filelist = explode(",",$filelst);
sort($filelist);

for ($count=1;$count<count($filelist);$count++) {
print " <tr>\n";
$filename=$filelist[$count];
$file_path = "$dir_name/$filename";
$filesize = filesize($file_path);
if (is_file($file_path)) {

  echo "  <td width=\"400\" height=\"25\" valign=\"middle\"><font face=\"Verdana\" size=\"2
border=\"0\"></a><a href=\"$dir_name/$filename\">$filename</font></a></td>\n";
  echo "  <td width=\"100\" height=\"25\" valign=\"middle\"><font face=\"Verdana\" size=\"2
\">$filesize bytes</font></td>\n";

}
elseif(($filename != ".") && ($filename != "..")) {
}
print " </tr>\n\n";
}
?>
