PunBB 1.3 integration

Forum integration is very useful when you want to use the same database for your website as the forum one or if you want to execute some tasks that require the user to be a part of a certain usergroup. Below you will find some integration possibilities.

General

In order to use PunBB user authentication within your scripts or to have access to the logged in user's information you have to include common.php which can be found in the include/ folder. You have also to define the FORUM_ROOT global variable in your script. For example, if your website front page is located in /home/user/public_html/ and your forums are located in /home/user/public_html/forums/, your FORUM_ROOT should be './forums/'. It can be done like this:

<?php
 
// Add these lines in the very top of your code
define('FORUM_ROOT', './forum/');
require FORUM_ROOT.'include/common.php';
 
?>

URL schemes

PunBB 1.3 natively supports URL rewriting, including SEF URLs.

How to enable URL rewriting:

  1. Rename file .htaccess.dist in the root of your forum to .htaccess.
  2. Go to Administration ⇒ Settings (/admin/settings.php?section=setup), find URL Scheme section there.
  3. Choose the URL scheme you like and save changes.

Template customization

How to include my file into *.tpl?

Use the forum_include “file.ext” substitute to include the file <FORUM_ROOT>/include/user/file.ext:

<!-- forum_include "file.ext" -->

Common tasks

Recent 10 posts

<?php
 
header('Content-type: text/html; charset=utf-8');
 
define('RECENT_POSTS_SHOW_POST', true); // Set to false to show topic subject only
define('RECENT_POSTS_MAX_POST_LENGTH', 20); // Limit length of the post text displayed
 
if (!defined('FORUM_ROOT'))
	define('FORUM_ROOT', './');
 
require FORUM_ROOT.'include/common.php';
 
// Get 10 lastest posts
$query = array(
	'SELECT'	=> 'p.id, p.message, t.subject',
	'FROM'		=> 'posts AS p',
	'JOINS'		=> array(
		array(
			'LEFT JOIN'		=> 'topics AS t',
			'ON'			=> 'p.topic_id = t.id'
		)
	),
	'ORDER BY'	=> 'p.posted DESC',
	'LIMIT'		=> '0,10'
);
 
$result = $forum_db->query_build($query) or error(__FILE__, __LINE__);
 
$recent_posts = array();
while ($cur_post = $forum_db->fetch_assoc($result))
	$recent_posts[] = $cur_post;
 
// Print out posts
if (!empty($recent_posts))
{
	?>
	<ul>
	<?php
	foreach($recent_posts as $cur_post)
	{
 
		echo '<li><a href="', forum_link($forum_url['post'], $cur_post['id']), '">', $cur_post['subject'], '</a>';
 
		if (RECENT_POSTS_SHOW_POST)
		{
			if (utf8_strlen($cur_post['message']) > RECENT_POSTS_MAX_POST_LENGTH)
				$cur_post['message'] = utf8_substr($cur_post['message'], 0, RECENT_POSTS_MAX_POST_LENGTH).'...';
 
			echo '<br />', "\n", $cur_post['message'];
		}
 
		echo '</li>';
	}
	?>
	</ul>
	<?php
}
 
?>

Showing all topics
