loop over a directory??

[bdee1]

i would like to loop over a directory and output any subdirectories in a select box.

i just started using PHPSlideshow script from greg lawler and i would like to add a select box so that i can just choose a folder to view and it will refresh the page and display the pictures from the selected folder.

any advice on how to do this would be appreciated.

You can use glob() with the GLOB_ONLYDIR option to get an array of subdirectories

$subDirectories = glob($directory, GLOB_ONLYDIR);
print_r($subDirectories);

ok that works i used the following code:

$subDirectories = glob("*", GLOB_ONLYDIR); 
echo "<strong>Subfolders</strong><br />";
echo "<form name=\"form1\" action=\"./phpslideshow.php?directory=\"ChosenFolder\" method=\"POST\">";
echo "<select name=\"folders\" onChange=\"form1.submit();\">";
echo "<option value=\"Choose a Folder\">Choose a Folder</option>";
foreach ($subDirectories as $folder)
{
	echo "<option value=\"" . $folder . "\">" . $folder . "</option>";
}
echo "</select>";
echo "</form>";

that outputs a select box with an entry for each subdirectory. but now i am wondering to put for the form action attribute. basically i want the form action to be the same page i am no with ?directory=chosendirectory appended where chosendirectory is the directory name chosen in the select.

now i knwo that i can access the form variable by saying $POST['folders'] but i can only access that AFTER the form is submitted.

so how can i properly set the form action here?
