scan a folder and get names of all folders within that folder?

[ztealmax]

it me again  ;D

is it possible to scan a folder and get names of all folders within that folder as a list or a dropdown selection menu?
If yes, a small example would be superb :D
//Cheers

Yes. if you just want folders
[code]<?php
$dir = ".";
if ($handle = opendir($dir)) {
  while (false !== ($file = readdir($handle))) {
    if($file != "." && $file != ".."){
      if(filetype($file) == "dir"){
      echo "$file<br>";
      }
    }
  }
closedir($handle);
}
?>[/code]

If you want them in a dropdown manu
[code]<?php
$dir = ".";
$dir_array=array();
if ($handle = opendir($dir)) {
  while (false !== ($file = readdir($handle))) {
    if($file != "." && $file != ".."){
      if(filetype($file) == "dir"){
      $dir_array[] = $file;
      }
    }
  }
closedir($handle);
}
echo "<select name=directories";
foreach($dir_array as $folder){
echo "<option value='".$folder."'>".$folder."</option>
}
echo "</select>";
?>[/code]

nice thank you, but where do i enter wich folder to scan for example:

themes/
//Martin :)
All that shows now i a blank page!


tried to enter it at:
[code]$dir = "themes/";  [/code]but didnt work

[craygo]

the $dir would be in reference to the current directory the page you are viewing is in.

$dir = "./themes";

To make it absolute put the absolute path.
$dir = "/home/craygo/public_html/themes";

Thank you it works like a charm :D

[ztealmax]

hmm , no i didnt get it to work
this is the foldername i have in my root
themes/

scanfolder.php is in the root directory of my wabsite

so this is the code im trying that you gave me:

[code]
<?php
$dir = ".";
if ($handle = opendir($dir)) {
  while (false !== ($file = readdir($handle))) {
    if($file != "." && $file != ".."){
      if(filetype($file) == "dir"){
      echo "$file<br>";
      }
    }
  }
closedir($handle);
}
?>
[/code]

if i use it as it is, it scans root and shows all directories there, however i would like it to scan my themes folder so
i added this as you suggested:

[b]$dir = "./themes";[/b]

also tried

[b]$dir = "themes/";[/b]

well and every other way i could think of, but it doesnt scan that folder, nothing happens!

//Martin
* anyone can answer this , would be great;) *

[ztealmax]

Still unresolved, anyone? :)

What is the absolute path to your themes directory?

[ztealmax]

well i was hopping not be able to use the absolute path, or if its possible to use a script that check absolute path

couse if i want to use this on another server there would be a problem :)

//Thanx

glob() is SOO much faster

[code]
$files=glob('images/*');
echo '<select>';
foreach($files as file) echo '<option>'.$file.'</option>';
echo '</select>';
[/code]

you dont need an absolute path either

yes but it only checks what files are in it, not the folders?

[taith]

[code]$files = glob('*');
foreach($files as $file){
if(strpos(".",$file,1)==false) echo $file;
}[/code]

}[/code]
[/quote]

thanx,
anyway to make it just scan folders and not the files within?
And if its possible just to show the folders in the folder not the whole path
themes/themename

themename = a folder
theme/ = is the one i dont want to show in drop down menu ;)

hmm thank you for your help, but i cant get it to work?

scanfolder.php as i called it
doesnt lay in the themes folder its outside it.

i tried changing it to this:
./themes
and
/themes

but it doesnt show anything... got any ideas whats wrong?

[JP128]

What is the main directory that scanfolder is in? And what is the main for themes?

im in to root directory where scanfolder.php is
and that should scan "themes/" folder thats also in root :)

Give this a whizz:

[code]<?php
$directory = './themes/'; // include trailing slash!
if($handle = opendir('./themes'))
{
while (false !== ($file = readdir($handle)))
{
if(is_dir($directory . $file))
{
echo $file;
}
}

closedir($handle);
}
?>[/code]

sweet :D

THanx alot , workes like a charm ;)

[heckenschutze]

FYI, a few mistakes the others were making,

[code]
$dir = "../themes";
...
foreach ($files as $file){
if(is_dir($file)){
...
[/code]

Remember, unless "../themes" is our working directory this will not return "expected" results... Since we're checking if ../themes/%folder% is a folder in ./%folder% ...
anyway HTH!

[Nicklas]

you can use glob() with the [i]GLOB_ONLYDIR[/i] parameter

ex
[code]<?php

$path = "themes"; // path to the dir you want to scan

foreach(glob("$path/*", GLOB_ONLYDIR) as $dir) {

echo basename($dir) . "<br />\n";

}

?>[/code]
