Re: [PHP] Menu from Directory

Having looked at it, it seems to be along the lines of what I was thinking
of... I would be very grateful if you could post the code, since I do think
it will be very useful. The main difference I was thinking of was to have a
menu in the form of a page of links, rather than a drop-down menu, but
having seen that, I would much prefer the drop-down menu approach!!!
Thanks very much, Ben.
Sorry I didn't get to this in a while -- had to fix my filters :)
Anyhow, the functions that I used to create my drop down box :
function getSubDir($rootdirpath) {
if ($dir = @opendir($rootdirpath))
{
$array[] = $rootdirpath;
while (($file = readdir($dir)) !== false)
{
if (is_dir($rootdirpath."/".$file)
&& $file != "." && $file != "..")
{
$array = array_merge($array,getSubDir($rootdirpath."/".$file));
}
}
closedir($dir);
}
return $array;
}
function getFiles($dirname) {
$handle=opendir($dirname);
while ($file = readdir($handle))
{
if($file=='.'||$file=='..')
continue;
else
$result_array[]=$file;
}
closedir($handle);
return $result_array;
}
The first function returns all the subdirs in a directory (given as
$rootdirpath).
The second functions returns an array of all files in a directory.
Simply combine these two functions to get a listing of all files in
subdirectories :
$subdirs = getSubDir("/path/to/main"); //no trailing /
array_shift($subdirs); //gets rid of the parent dir
$count = 0;
while (list(,$val) = each($subdirs)) {
$files[substr(strrchr($val,"/"),1,strlen(strrchr($val,"/")))] =
getFiles($val);
$count += count(getFiles($val));
}
This while loop gets a list of all the files and counts the total number
of files in the subdirs. The list of files is in an array called $files.
Now, to build the drop down :
while(list($key,$val) = each($files)) {
echo "Section $key :\n";
while(list(,$name) = each ($val))
{
echo " -=> ";
echo substr($name,0,strlen($name)-4);
echo "\n";
}
echo "\n"; // space
}
I hope this helps you out. Let me know if you can't understand anything :)

Anyway help would be greatly received! (I'm new to PHP, so simple help would be even more appreciated!) :S I wrote some code that might be what you want. It was for a reference download system. Here is what it does : 1. Scans a directory for all sub-directories 2. Scans those subdirectoties for files 3. Creates a drop down box with the appropriate categories (sub dir name ), and file listing. You can see it in action at http://www.meidomus.com (top left, marked REFERENCE DOWNLOAD) Let me know if this is what you were after and I will post the code. Its just two functions. -- Burhan Khalid phplist[at]meidomus[dot]com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Menu from Directory
You might want to start with searching the manual for opendir() function. There is a sample code listing all files from a directory. :) Niklas -Original Message- From: Ben Whitehead [mailto:[EMAIL PROTECTED] Sent: 2. huhtikuuta 2003 1:05 To: [EMAIL PROTECTED] Subject: [PHP] Menu from Directory I am trying to sort an image menu system which is passed a directory name, and can count and name the files in a menu from simply seeing which files are in this directory.
