Currently Active Topics

[Sarke]

I made this for my own forum, and I might as well share the code.

It's basically a block that is sort of like the "Recent" block, but it takes the 5 (or whatever number you want) most active topics by posts during the last 7 days (or however many days you want, decimals ok).  It's basically a list of the popular topics during the past week.

<?php

if (!defined('SMF'))

global $context, $user_info, $db_prefix, $scripturl;

$days = 7;
$limit = 5;

$time = time() - 60*60*24*$days;

$result = db_query("
SELECT b.ID_BOARD as board
FROM {$db_prefix}boards AS b
WHERE {$user_info['query_see_board']}
", __FILE__, __LINE__);

$boards = array();
while ($row = mysql_fetch_array($result))
{
$boards[] = $row['board'];
}
mysql_free_result($result);

$result = db_query("

I use it as an included file, but you should be able to just paste it in a phpblock.

EDIT: I just realised that I forgot to make it check permissions, so it will list all topics (even the ones the user can't access).  I'll look into it.
EDIT 2: Fixed the permissions thing.

Thanks for sharing it with us, I will give it a try

[Sarke]

I fixed the problemn where it didn't check permissions, so it's all good now. 

BTW, this can also be a "Daily topics" thing, if you just set $days = 1; if you have a really busy board you can set $days = 1/24 for hourly and the $limit = 1.  That would basically give you the one topic that has been the most active the last hour.

I tried this but I got the following error, can you tell me please why could that be, thank you

Parse error: parse error, unexpected '<' in /data/members/paid/d/o/mysite.com/htdocs/www/Sources/Load.php(1726) : eval()'d code(35) : eval()'d code on line 2

[jacortina]

If you are using it in a block, start at the "global" line and leave off the final line ("?>") and see if that clears up any errors.

[Sarke]

Yeah, just remove the php tags <?php and ?>.

[babjusi]

I will try it out again. Thank you both for your help

[kopijun]

Is it posssible to select topics from certain boards ?
