Showing posts on external page not working
#1
I want to show posts from a specific forum on a regular php page from my website. I tried to use the code from the last post this topic: https://community.mybb.com/thread-210775.html with mediocre results.

While the posts get shown correctly like

Post Title
Post Content
Posted by: username

I end up with getting these errors displayed on the same page just before the posts:

MyBB Internal: One or more warnings occurred. Please contact your administrator for assistance.

This is the code I put in the first row of the file /test/showcontent.php

<?php
chdir("./../forum/"); // path to MyBB
define("IN_MYBB", 1);
require_once("./global.php");
global $mybb, $db, $cache, $lang, $plugins;  // Trim this list of global vars, if you want to.
?>


And this code is inserted in the same document at the place where the posts should be shown

<?php
$query = $db->query("
    SELECT t.tid, t.fid, t.uid, t.username, t.subject, t.replies, t.views, t.lastposter, p.message
    FROM ".customboardprefix_."threads t
    INNER JOIN ".customboardprefix_."posts p ON (p.tid=t.tid)
    WHERE t.fid='2' AND t.visible='1'
    ORDER BY t.dateline DESC
    LIMIT 6"
	
); 
$list = '';
    while($fetch = $db->fetch_array($query))
    {
        $list .= "<strong><a href=\"forum/showthread.php?tid={$fetch['tid']}\">".htmlspecialchars_uni($fetch['subject'])."</a></strong><br />";
		$list .= "".htmlspecialchars_uni($fetch['message'])."<br>";
        $poster = "<a href=\"forum/member.php?action=profile&uid=".$fetch['uid']."\">{$fetch['username']}</a>";
        $list .= "Posted by: {$poster}<br /><br />";
    
    }
    //output
    echo $list;
?>


The error.log shows this:

I assume customboardprefix_ is self explanatory to the people with enough knowledge to help me out on this one.

Really looking forward to get this fixed since mybb is such a nice board compared to phpbb. I'm impressed.

Thank you for your time, I really appreciate everybody who is trying to help me
