Trying to resolve file path issue

[Carlos Avrard]

Working with a simple directory/file tree display solution (http://abeautifulsite. net/blog/2007/06/php-file-tree/)

I'm able to get the page to display properly, javascript works just fine as well, but I can't seem to get the correct file path on the file links.

here's the code:

<?php
		
$allowed_extensions = array("doc", "pdf");

echo php_file_tree($_SERVER['DOCUMENT_ROOT']."/er_test/forms", "[link]", $allowed_extensions);
	
echo php_file_tree("/er_test/", "javascript:alert('You clicked on [link]');");
		
?>

The file link is coming out like this:
d:\Inetpub\nocc aschool/er_test/forms/Student%20Forms/Student+Check-Out+Procedures. doc

I'm thinking that it could be something in how the website is structured, is there a work around or a manual way to set the path?

If needed here's the php_file_tree code:

<?php
/*
	
	== PHP FILE TREE ==

	== AUTHOR ==

function php_file_tree($directory, $return_link, $extensions = array()) {
	// Generates a valid XHTML list of all directories, sub-directories, and files in $directory
	// Remove trailing slash
	if( substr($directory, -1) == "/" ) $directory = substr($directory, 0, strlen($directory) - 1);
	$code .= php_file_tree_dir($directory, $return_link, $extensions);
	return $code;
}

function php_file_tree_dir($directory, $return_link, $extensions = array(), $first_call = true) {
	// Recursive function called by php_file_tree() to list directories/files
	
	// Get and sort directories/files
	if( function_exists("scandir") ) $file = scandir($directory); else $file = php4_scandir($directory);
	natcasesort($file);
	// Make directories first
	$files = $dirs = array();
	foreach($file as $this_file) {
		if( is_dir("$directory/$this_file" ) ) $dirs[] = $this_file; else $files[] = $this_file;
	}
	$file = array_merge($dirs, $files);
	
	// Filter unwanted extensions
	if( !empty($extensions) ) {
		foreach( array_keys($file) as $key ) {
			if( !is_dir("$directory/$file[$key]") ) {
				$ext = substr($file[$key], strrpos($file[$key], ".") + 1); 
				if( !in_array($ext, $extensions) ) unset($file[$key]);
			}
		}
	}
	
	if( count($file) > 2 ) { // Use 2 instead of 0 to account for . and .. "directories"
		$php_file_tree = "<ul";
		if( $first_call ) { $php_file_tree .= " class=\"php-file-tree\""; $first_call = false; }
		$php_file_tree .= ">";
		foreach( $file as $this_file ) {
			if( $this_file != "." && $this_file != ".." ) {
				if( is_dir("$directory/$this_file") ) {
					// Directory
					$php_file_tree .= "<li class=\"pft-directory\"><a href=\"#\">" . htmlspecialchars($this_file) . "</a>";
					$php_file_tree .= php_file_tree_dir("$directory/$this_file", $return_link ,$extensions, false);
					$php_file_tree .= "</li>";
				} else {
					// File
					// Get extension (prepend 'ext-' to prevent invalid classes from extensions that begin with numbers)
					$ext = "ext-" . substr($this_file, strrpos($this_file, ".") + 1); 
					$link = str_replace("[link]", "$directory/" . urlencode($this_file), $return_link);
					$php_file_tree .= "<li class=\"pft-file " . strtolower($ext) . "\"><a href=\"$link\">" . htmlspecialchars($this_file) . "</a></li>";
				}
			}
		}
		$php_file_tree .= "</ul>";
	}
	return $php_file_tree;
}

// For PHP4 compatibility
function php4_scandir($dir) {
	$dh  = opendir($dir);
	while( false !== ($filename = readdir($dh)) ) {
	    $files[] = $filename;
	}
	sort($files);
	return($files);
}

Thanks,

To manually set the path is as simple as replacing:

$_SERVER['DOCUMENT_ROOT']."/er_test/forms

with:

path/to/file/

I'm still not sure what exactly you want?

[Carlos Avrard]

First of all, thanks for the reply.

The issue I'm having is that the link to download the files that are displayed through the file tree can't be downloaded because the url is malformed.

It shows up for example as:

d:\Inetpub\noccaschool/er_test/forms/form_name.pdf

instead of:

http://www.nocca.com/er_test/forms/form_name.pdf

Does that help?

Thanks

Hmmmm... I have never tried to do that but it seems simple.

When I use $_SERVER['DOCUMENT_ROOT'] I get:

/home/username/public_html/

However mine is remotely hosted, so I image that that is the difference.
$_SERVER['HTTP_HOST'] and $_SERVER['SERVER_NAME'] both return my domain name with the domain extension. What do those return on yours?

If on the small chance that they do return your domain, then you can use something like:

echo "http://".$_SERVER['SERVER_NAME']."/er_test/forms";
