I want to create a dynamic page that will...

swjohnson

reside in the parent directory and read the contents of multiple child directories.

Then build the page that will allow download of the files within the child directories.

Any ideas how to get started? Or should I take this to a more advanced forum on this site?

Do you want the browser to show a prompt window to know what the user want to do with the file ??

swjohnson

I want the browser to display the url to the individual files.

i.e.

Of course, this being written in html only gives an approximation of what I want it to do. But it should be enough to give you the idea.

$url should contain the url
$parent should contain the parent directory
$child should contain the subdirectory where the files actually reside.

I am assuming that I will need a for loop of some kind so I can walk through the parent directory as well as walk through the child directory.

I am also assuming that this will end up in an array so childname and the filename are not overwritten.

If I was still in a dos environment, I could do probably it in dbase, but am at a loss in PHP.

Does ANYONE have the name of a good print PHP Bible?

Howdy,

Sounds like you need recursion.

The code below contains a function called rec() that:

takes a directory as its single argument

reads all files (& dirs) inside, and then does EITHER:

if a plain file, push the filename onto the array
if a directory, call rec() on that directory, and push all the results of THAT call (an array) onto the end of the array...

<?php
function rec($here) {
	$entries = array();
	if ($handle = opendir($here)) {
		while (false !== ($file = readdir($handle))) {
			if( $file == '.' || $file == '..' ) {
				continue;
			} else if (is_dir($here.'/'.$file)) {
				array_push($entries,'<b>'.$here.'/'.$file.'/</b>');
				$tmp = rec($here.'/'.$file);
				foreach($tmp as $e) {
					array_push($entries,$e);
				}
			} else if (is_file($here.'/'.$file)) {
				array_push($entries,$here.'/'.$file);
			}
		}
		closedir($handle);
	} else {
		echo "<li><b style=\"color:red\">Cannot opendir() $here</b>";
	}
	return $entries;
}

// The call to the recursive function....
$e = rec($_SERVER['DOCUMENT_ROOT']);
foreach($e as $x) {
	echo '<li>'.$x;
}
?>

The initial call to the rec() function can be '.' for the directory in which the script resides, or an absolute directory like '/home/users/~sw/htdocs/tree'

Hope that helps.

The function below open a directory, reads it content and show it. You should modify it to do what you want...

function Aff_Dir($rep, $aff, $esp) {
	$rpt = opendir($rep);
	while(($fch = readdir($rpt)) !=false) {
		if($fch !="." && $fch !="..") {
			if(is_dir($rep . $fch)) {
				echo "<STRONG>";
				echo "$esp$aff$fch<BR>";
				echo "</STRONG>\n";
			}
			if(is_file($rep . $fch)) {
				echo "$esp$fch<BR>\n";
			}
		}
		if(is_dir($rep . $fch) && $fch !="." && $fch !="..") {
			Aff_Dir($rep . $fch . "/", $aff . "$fch > ", "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$esp");
		}
	}
}
Aff_Dir("C:/Downloads", "Home > ", "");

How to call it :

Aff_Dir($rep, $aff, $esp);
$rep is the directory you want to open (put a slash (/) at the end)
$aff is what you want to print before each directory
$esp you should let it blank. It's simply the space before the left border of the broswer and the first character of each line. If you look in the code, you will see that I used   which is a space.

Couldn't you please write something in the body of your message and not only in your title ? I hate seeing "...". Personnally, it means " It doesn't matter for me "... thanks.

swjohnson

Do Not Open. I suppose I could have used (NM) for No Message.

But in any case. Thank you for your code. I am in the process of seeing which of the codes provided will do what I want it to do.
