Forums block to only show posts from one Forum Category

Hi

if you have different forum categories and you want a block to only show posts from one forum category how would you do it? Here is the code to my forums block:

Code:




<?php





if (eregi("block-Forums.php", $_SERVER['PHP_SELF'])) {


    Header("Location: index.php");


    die();


}





global $prefix, $db, $sitename;





$result = $db->sql_query("SELECT forum_id, topic_id, topic_title FROM ".$prefix."_bbtopics ORDER BY topic_last_post_id DESC LIMIT 20");


$content = "<br>";


while ($row = $db->sql_fetchrow($result)) {


    $forum_id = intval($row['forum_id']);


    $topic_id = intval($row['topic_id']);


    $topic_title = $row['topic_title'];


    $title1 = substr("$topic_title", 0,18);


    $row2 = $db->sql_fetchrow($db->sql_query("SELECT auth_view, auth_read FROM ".$prefix."_bbforums WHERE forum_id='$forum_id'"));


    $auth_view = intval($row2['auth_view']);


    $auth_read = intval($row2['auth_read']);


    if (($auth_view < 2) OR ($auth_read < 2)) {


        $content .= "<a href=\"modules.php?name=Forums&amp;file=viewtopic&amp;t=$topic_id\">$title1...</a><br>";


    }


}











?>

e.g. if I want to show posts from category 7 like at this url:
http://www.ravenphpscripts.com/forumsindex-c-7.html

what would I have to adjust in the block code?

Hi

I've taken a look at that post and I'm a bit stumped. I can't get it to work. From the code I supplied above how do I specifiy to pull posts from more than one forum_id?

e.g. if I only want to show posts from forum_id 2, 3 and 4?
I would appreciate any help from anybody who can help me change the code above.

again I apologize if there is an obvious solution but I just can't get it to work Embarassed

hi

I managed to return the results from one forum id by doing adding a WHERE statement like this:

Code:

SELECT forum_id, topic_id, topic_title FROM ".$prefix."_bbtopics WHERE forum_id=1 ORDER BY topic_last_post_id DESC LIMIT 20

this works.
however i need to return specific forum id's such as forum id 1, 2 and 3. how do i return more than one forum id?

Code:

WHERE forum_id IN(1,3,23)

Change the numbers to whatever numbers you need.

aah yes that works.

thanks so much for your help. Much appreciated.

Just another question, is there an opposite of using IN e.g. if I wanted to exclude only one forum_id number what could I use instead of IN?

e.g. show all forum_id's expect for forum_id number 3?

is there a way to do that?

!IN()

thanks, I also tried NOT IN and that also works!

sorry for being a pest but everyday is a learning experience for me. Thanks again for your help.

! = NOT

I tried "where t.forum_id=f.forum_id IN(34,35,36)" in the following ... but it gives me blank tables. Can you help me fix it Raven, please?

Code:

$result = sql_query( "SELECT t.topic_id, f.forum_name, f.forum_id, t.topic_last_post_id, t.topic_title, t.topic_poster, t.topic_views, t.topic_replies, t.topic_moved_id FROM ".$prefix."_bbtopics t, ".$prefix."_bbforums f where t.forum_id=f.forum_id IN(34,35,36)ORDER BY topic_last_post_id DESC", $dbi );


while( list( $topic_id, $forum_name, $forum_id, $topic_last_post_id, $topic_title, $topic_poster, $topic_views, $topic_replies, $topic_moved_id ) = sql_fetch_row( $result, $dbi ) )

Code:

where f.forum_id IN(34,35,36) AND t.forum_id=f.forum_id
