# This script allows a user to make post their favorite color on the website.

# See it in action at: http://practicalproductivity.com/sqlefs/colorlog.php
### This file just handles your login details and sets the volume. ###

### Or you could specify that stuff in your script like so ###
# require_once '../sqlefs.class.php';
# $efs = new efsclass();

# $efs->cd('c:/');
$showlen = 10; # show this many entries

### Set the current working directory. ###

# view comments

<p>Enter your name and favorite color!</p>

<input type="text" name="name" placeholder="Name" size="' . $namelen . '">
<input type="color" name="color">
<input type="submit">
</form>
</div>
';
### Retrieve a listing of files and reverse it so newest are first. ###

# We intend to limit the number of entries we show...
# SQLEFS orders file listings by oldest first by default,
# so we'll just delete the first files in the listing
# until we have the right number to show.
### Retrieve file listing. ###
