   Hi guys,

   Is there a way i can get the first "n" characters of the first post in a topic so i can make them appear in the forum main page, under each topic's title?

   Thanks!
   :)phollo

   You mean you want the first X characters or words from a first post?

   This is possible. I am playing with this myself so users of my bbPortal plugin can use a read more button on the portal if they want to. It wil count the first 100 words and then ad a read more link.

   Think this is something you want (without the read more link). This can be done with a plugin and a new function. I haven't got something working yet else I would post it here...

   try this..
   create a plugin with this code..

   function your_function_name($where) {
global $topic;
return $where . ' AND topic_id = ' . $topic->topic_id;
}
function get_first_post_of_current_topic() {
add_filter('get_latest_posts_where','your_function_name');
get_latest_posts(1);
}

   call get_first_post_of_current_topic in the loop where you show tipc name.
   let me know if works.. this is just a hunch

   cheers

   ok..
   try this plugin

   <?php
function your_function_name($where) {
global $topic;
if ($topic)
return $where . ' AND topic_id = ' . $topic->topic_id;
else
return $where;
}
function get_first_post_of_current_topic() {
global $bb_post;
add_filter('get_latest_posts_where','your_function_name');
$bb_post = get_latest_posts(1);
if(count($bb_post) == 1 ) {
$bb_post = $bb_post[0];
post_text();
}
}
?>

   where you want call get_first_post_of_current_topic();

   so1o, thanks, that looks better, but it grabs the last post of the topic, not the first one..

   ..
   by declaring $bb_post = $bb_post[0]; i assume $bb_post is an array. now, since i see appearing the last post of a topic i tried to substitute that line with $bb_post = end($bb_post), thinking that maybe the actual first post stayed at the end of the array; i still get the last post though.. any other suggestion?

    Sorry, phollo, can't offer any meaningful help here, but I did just want to say that I'm interested in seeing your results.

    $first_post = $bbdb->get_results("SELECT * FROM $bbdb->posts WHERE topic_id = $topic->topic_id AND post_position = 1");

    That will give you the post OBJECT... from there you can pull out the text like this:

    echo $first_post->post_text;

    Or since it seems you want to pull out just the first little bit, just use a php string function to make it look and act like you want it to.

    It's not the most eloquent method, but it's certainly simple.
