Simple Machines Community Forum

I have a fantastic recent posts block with columns of information. Unfortunately the block slows down my forum so I can't use it.
What can I do to fix the code? Any suggestions?

The code:

The Setup is inside the tab!
Have Fun,

Are you do all boards?
If so change
$num_recent = 30;   
$include_boards = null;

Thanks a lot! It seems faster now. Anyway I want to exclude one board. How can I do that? The boards is number 110.

Also you could add some cache to the query (1 minute or something) if the forum is not extremely active to make it even faster.

For excluding boards you can use the same you were using for including them in the first post.


$exclude_boards = array(1,3,etc);


AND b.id_board NOT IN ({array_int:exclude_boards})

array(
'current_member' => $user_info['id'],
'exclude_boards' => empty($exclude_boards) ? '' : $exclude_boards,
) 

Ok its nice,
how to add member or poster avatar to it??
Thanks.

I want to keep only topic and remove posts please help :)
