Yeah, the processor sucks.

I'd rather buy a netbook.

Correct.

Try using cURL:

<?php

$url = 'http://google.com/';

if (function_exists('curl_init')) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $content = curl_exec($ch);
    curl_close($ch);
    
    echo $content;
}
else echo 'No cURL library!';

?>

A great place to start is http://fluxbb.org/wiki/v1.3:developing_extensions, then I'd recommend reading other extension's code to familiarize yourself with the extension system.

This worked for me:

UPDATE pun_forums AS f SET num_posts=(SELECT SUM(num_replies) FROM pun_topics WHERE forum_id=f.id)+(SELECT count(id) FROM pun_topics WHERE forum_id=f.id)

Replace the 'pun_' prefix with your tables' prefix.

It'll work as long as the forums have 1 or more topics.

They work on my test board.

Create a new file on the same directory of your 'index.php' with the following code in it

<?php
if(chmod("./extensions", 0777))
echo 'Success';
?>

and name it 'chmod.php'.

Then, just access the file with your browser (i.e. www.example.com/forums/chmod.php).

If you get "Success", then you're good to go.

You do realize that by just getting that info from the database you're not changing the $forum_user variable at all, don't you? There's only one guest user account and its last_visit is never updated, so there's no need to add a check for $forum_user['is_guest'].

Also, not everyone has $lang_index['Today online'], so they're gonna get "Undefined index".

The only thing wrong with my code would be the table prefix. And here it's fixed:

$todays_users = array();
$result = $forum_db->query("SELECT id,username FROM ".$db_prefix."users WHERE last_visit>'".strtotime(gmdate("M d Y"))."' ORDER BY last_visit DESC");
while(list($id, $username) = $forum_db->fetch_row($result)) $todays_users[] = '<a href="'.forum_link($forum_url['user'], $id).'">'.$username.'</a>';
if(!empty($todays_users))
echo '<h3 class="hn"><span>Online today: '.implode(', ', $todays_users).'</span></h3>';

Sort of.

Well, I think the problem is that the last_visit value is updated only when you log in (not when you visit the site).
