[Resolved] showing folder list

[jonzy]

Pulling my hair out!

I have a script where I can move a file and these functions list the folders and subfolders, and I'm trying to indent the subfolders each time.

Example

Folder
   folder1
      sub folder
   folder2
another folder
   folder3
   folder4
      subfolder2
      subfolder3
         subsubfolder

So each sub folder gets indented 3 spaces

My script works for the first few folders, but then the rest are all aligned and you can't really tell that some are subfolders of another.

Please help... it can be called by the function direcho2

function dirsubecho($path) {

   if ($dir = opendir($path))
   {
      while (false !== ($file = readdir($dir)))
      {
      $subcount .= "   ";
                         if (is_dir("$path/$file") && $file != '..' && $file != '.')
                         {
                              echo "<option value=\"$path/$file/\"";
                              echo ">$subcount$file</option>\n";
                                 dirsubecho("$path/$file");
                              $subcount = substr($subcount, 0, -18);

                     }
            unset($file);

            }
                 closedir($dir);
     }
}

function direcho2($path) {

   if ($dir = opendir($path))
   {
      while (false !== ($file = readdir($dir)))
      {
                         if (is_dir("$path/$file") && $file != '..' && $file != '.')
                         {
                              echo "<option value=\"$path/$file/\"";
                              echo ">$file</option>\n";
                                 dirsubecho("$path/$file");
                         }
                unset($file);
                }
                     closedir($dir);
         }
}

Try this

<?php

/*
    base is where we start from it never changes
    directory starts off with the base however it will 
    eventually hold subfolders and other folders of the base
*/
function getDir($base, $directory)
{
    if (is_dir($directory))
	{
        if (substr($directory, -1) == "/")
			$path = substr($directory, 0, -1); //get rid of /
        $dh = opendir($directory);

    while (($file = readdir($dh)) !== false)
    {
        if ($file != '.' && $file != '..')
            if (is_dir($directory."/".$file))
            {
                echo str_repeat("&nbsp;", pad($base, $directory."/".$file) * 3). $file."<br />";
                getDir($base, $directory."/".$file);
            }
    }
}
closedir($dh);
}

/*
    This function finds out exactly how far deep we are
    within the base and returns the level which we will then 
    use again getDir. If the directory is only a sublevel e.g. 
    first level of base we wont pad
*/
function pad($base, $curDir)
{
    if (substr($base, -1) != '/')
        $base .= '/';
    $baseLength = strlen($base);
    $dirAbovebase = substr($curDir, $baseLength);
    $size = sizeof(explode("/", $dirAbovebase));

if ($size == 1)
    return 0;
else
    return $size - 1;
}

getDir('your_start_dir', 'your_start_dir');

?>

Hopefully the comments explain a little. However to get this to work you need to know where you started from, thus why we have $base which never changes and $directory which when we call the function should be identical to $base. Of course $directory will change. As we go deeper into the directory structure.

The pad function works out how far we are it isnt a fool proof function but it seemed to work quite well for myself anyway. The function basically returns a value of type Int which we then times with 3 to give the spaces. Now if we are in the first level i.e. the first sub directory of the base we return 0 and as we all know 0 * 3 = 0 thus no spacing be given. Eventually there will be however we need to -1 to it as it will give a result 1 bigger than it should.

I hope this is what your after or just on there.

Worked awesome! I made a few changes for my script and tested it. Thanks for the help.
