Hi,

 

Im new to php and have been trying to put together a simple image hosting site with code that ive found around the internet. I've got things working but I want the images in the gallery to display the latest uploaded first.

 

This is the code im using to display the images

 

<html>
  <head>
    <title>Slideshow</title>
    <style>
    </style>
  </head>
  <body>
    <?php
      require 'config.php';
      $offset=0;
      if(isset($_GET['offset'])) {
        $offset=$_GET['offset'];
      }
      $rowcount=1;
      $perc=round((1/$imgperrows)*100);
    ?>
    <table width="100%">
      <tbody>
        <tr>
        <?php
          $d=dir("files");
          $count=0;

          while (false !== ($entry = $d->read())) {
            if($entry!='.' && $entry!='..') {


              if($count>=$offset && $count<($offset+$imgperpage)) {
                if($useshrinked) {
                  if(file_exists('tmb/'.$tmbprefix.$entry)) {
                    echo '<td width="'.$perc.'%" align="center"><a href="images/'.$entry.'"';
                    if($launchnew) echo ' target="_blank"';
                    echo '><img src="tmb/'.$tmbprefix.$entry.'" width="80" height="80" border="0"><br>'.$entry.'</td>';
                  } else {
                    echo '<td width="'.$perc.'%" align="center"><a href="files/'.$entry.'"';
                    if($launchnew) echo ' target="_blank"';
                    echo '><img src="files/'.$entry.'" width="80" height="80" border="0"><br>'.$entry.'</td>';
                  }
                } else {
                  if(file_exists('tmb/'.$tmbprefix.$entry)) {
                    echo '<td width="'.$perc.'%" align="center"><a href="files/'.$entry.'"';
                    if($launchnew) echo ' target="_blank"';
                    echo '><img src="tmb/'.$tmbprefix.$entry.'" width="80" height="80" border="0"><br>'.$entry.'</td>';
                  } else {
                    echo '<td width="'.$perc.'%" align="center"><a href="files/'.$entry.'"';
                    if($launchnew) echo ' target="_blank"';
                    echo '><img src="noprev.gif" width="80" height="80" border="0"><br>'.$entry.'</td>';
                  }
                }
                $rowcount++;
                if($rowcount>$imgperrows) {
                  echo '</tr><tr>';
                  $rowcount=1;
                }
             }
             $count++;
          }
          }
          $d->close();
        ?>
        </tr>
      </tbody>
    </table>
    <br>
    <center>
      <input type="button" value="Previous" style="font: 11px bold arial;width:70px;"<?php if($offset==0) { ?> DISABLED<?php } ?> onClick="window.location='index.php?offset=<?php echo $offset-$imgperpage; ?>';">
       
      <input type="button" value="Next" style="font: 11px bold arial;width:70px;"<?php if($count>$offset && $count<=($offset+$imgperpage)) { ?> DISABLED<?php } ?> onClick="window.location='index.php?offset=<?php echo $offset+$imgperpage; ?>';">
    </center>

 

The uploading code im using creates a log file with upload times in it.

 

Can anyone give me some help and point me in the right direction?

$files = sortarrayByDate($files,'docs');
?>
