need to modify so directory list is ordered by date

stagecoach · February 25, 2007

I found this on the web and it works great except I can not figure out how to set the list to order by date only. I am trying to set up a page in which I upload newsletters in PDF for other people to download. I will then remove the sort function so that other web users can not use them.

Thanks,

Paul

Here is the script

<?

/*

Directory Listing Script - Version 2

====================================

Script Author: Ash Young <[email protected]>. www.evoluted.net

Layout: Manny <[email protected]>. www.tenka.co.uk

REQUIREMENTS

============

This script requires PHP and GD2 if you wish to use the

thumbnail functionality.

INSTRUCTIONS

============

1) Unzip all files

2) Edit this file, making sure everything is setup as required.

3) Upload to server

4) ??????

5) Profit!

CONFIGURATION

=============

Edit the variables in this section to make the script work as

you require.

Start Directory - To list the files contained within the current

directory enter '.', otherwise enter the path to the directory

you wish to list. The path must be relative to the current

directory.

*/

$startdir = '.';

/*

Show Thumbnails? - Set to true if you wish to use the

scripts auto-thumbnail generation capabilities.

This requires that GD2 is installed.

*/

$showthumbnails = true;

/*

Show Directories - Do you want to make subdirectories available?

If not set this to false

*/

$showdirs = true;

/*

Force downloads - Do you want to force people to download the files

rather than viewing them in their browser?

*/

$forcedownloads = false;

/*

Hide Files - If you wish to hide certain files or directories

then enter their details here. The values entered are matched

against the file/directory names. If any part of the name

matches what is entered below then it is now shown.

*/

$hide = array(

'dlf',

'index.php',

'Thumbs',

'.htaccess',

'.htpasswd'

);

/*

Show index files - if an index file is found in a directory

to you want to display that rather than the listing output

from this script?

*/

$displayindex = false;

/*

Allow uploads? - If enabled users will be able to upload

files to any viewable directory. You should really only enable

this if the area this script is in is already password protected.

*/

$allowuploads = false;

/*

Overwrite files - If a user uploads a file with the same

name as an existing file do you want the existing file

to be overwritten?

*/

$overwrite = false;

/*

Index files - The follow array contains all the index files

that will be used if $displayindex (above) is set to true.

Feel free to add, delete or alter these

*/

$indexfiles = array (

'index.html',

'index.htm',

'default.htm',

'default.html'

);

/*

File Icons - If you want to add your own special file icons use

this section below. Each entry relates to the extension of the

given file, in the form <extension> => <filename>.

These files must be located within the dlf directory.

*/

'png' => 'jpg.gif',

'jpeg' => 'jpg.gif',

are doing!
