Drop-Down Boxes from Directory Tree

[fuddy]

I have a directory structure that is constantly being updated.

 

Config (Root)

--City (Sub-Dir)

----Address (Sub-Dir)

------File

 

I'm trying to create a script that will:

 

1. Scan a directory (will be a root dir) and place the directory names in a drop down box.

 

2. Choose option (dir) and a 2nd box will appear with subdirectores

 

3. Once you select an option, a 3rd will be presented

 

4. This directory will have 1 file that needs to be downloaded

 

<?php

$dir = "D9034-Configs";
if (isset($_GET['Site'])) { $Site = $_GET['Site']; } else { $Site = $_POST['Site']; }
if (isset($_GET['IP_Address'])) { $IP_Address = $_GET['IP_Address']; } else { $IP_Address = $_POST['IP_Address']; }

if (!(isset($Site)))
{
?>
<form id="form1" name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']?>">
<select name="Site" id="Site">
<?php
$output = shell_exec('ls ./'.$dir.'/');
$dirs = explode("\n", $output);
foreach ($dirs as $key => $value)
{
?> <option value="<?php echo $value?>"><?php echo $value?></option><?php
}
?>
</select>
</form>
<?php
}

if (isset($Site))
{
?>
<form id="form1" name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']?>">
<select name="Site" id="Site">
<?php
$output = shell_exec('ls ./'.$dir.'/');
$dirs = explode("\n", $output);
foreach ($dirs as $key => $value)
{
if ($value == $Site)
{
?> <option value="<?php echo $value?>" SELECTED><?php echo $value?></option><?php
}
else
{
?> <option value="<?php echo $value?>"><?php echo $value?></option><?php
}
}
?>
</select>
<select name="IP_Address" id="IP_Address">
<?php
$output = shell_exec('ls ./'.$dir.'/'.$Site.'/');
$dirs = explode("\n", $output);
foreach ($dirs as $key => $value)
{
?> <option value="<?php echo $value?>"><?php echo $value?></option><?php
}
?>
</select>
</form>
<?php
}

?>
