Directory/File Tree With Hyperlinks

rio38 · September 25, 2007

I am trying to create a page that will list a directory/file tree and allow the user to click on the filename to download the file.

I have several directories with many files in each directory. I would like the directory names listed with no hyperlink, but the filenames listed underneath the directory name and indented a bit with a hyperlink to the file location.

I did download a directory tree script from the web and it works fairly well, but I can not figure out how to get the hyperlink functionality working.

Can anyone help me with this?

Thanks in advance.

could you like to post the script?

I apologize:

<?php			
function traverseDirTree($base,$fileFunc,$dirFunc=null,$afterDirFunc=null){
  $subdirectories=opendir($base);
  while (($subdirectory=readdir($subdirectories))!==false){
    $path=$base.$subdirectory;
    if (is_file($path)){
      if ($fileFunc!==null) $fileFunc($path);
    }else{
      if ($dirFunc!==null) $dirFunc($path);
      if (($subdirectory!='.') && ($subdirectory!='..')){
        traverseDirTree($path.'/',$fileFunc,$dirFunc,$afterDirFunc);
      }
      if ($afterDirFunc!==null) $afterDirFunc($path);
    }
  }
}

function outputPath($path){
  $level=substr_count($path,'/');
  for ($i=1;$i<$level;$i++) echo '   ';
  echo basename($path);
  echo "\n";
}
echo '<pre>';
traverseDirTree('./clientarea/','outputpath','outputpath');
echo '</pre>';
?>

rarebit,

I can't send private messages yet, but you will be a lifesaver if you could help me out.

Also, I really do not want it to display the '.' and '..' in the list if possible.

Thank you in advance.

I have not tested this, just catch the logic.

function outputPath($path){

//here just put the unnecessary path coming in $path with the your domain name

$webPath=str_replace("/www/...","http://www.test.com/",$path);

$level=substr_count($path,'/');

for ($i=1;$i<$level;$i++) echo ' ';

echo "<a href='" . $webPath . "'>" . basename($path) . "</a>";

echo "\n";

}

just so you know you can accomplish the same idea with a public ftp account, php can even handle the logging in of it. Instead of trying to manually display the files and so forth

CoolDude,

I am open to any suggestions. How would PHP handle the login for an FTP account?

rarebit: I will try this out. Thanks and let me know if you can expand on it.

Thanks.

Got a bit carried away, sort of started redoing it (I just can't handle it unsorted or files b4 folders!), here's two ways, but they can be simplified somewhat...
