That's cause by this function. Can you try replacing that entire function with the one below and let me know if it works? I'm not on my normal development computer.

If that one doesn't work, give this one a go.

The code on GitHub looks fine to me.

• $sql_ary['LEFT_JOIN'][] .= array(...); won't work as .= is only applicable to strings.

• Code: Select all

  $sql_ary['FROM'][] = array(
      POSTS_TABLE     => 'p',
      TOPICS_TABLE    => 't',
  ); 

  This would result in the array below which doesn't look quite right.
  

  Code: Select all

  array(
  	FORUMS_TABLE		=> 'f',
  	array(
  		POSTS_TABLE     => 'p',
  		TOPICS_TABLE    => 't',
  	)
  );

  This should work:
  

  Code: Select all

  $sql_ary['FROM'] = array_merge($sql_ary['FROM'], array(
      POSTS_TABLE     => 'p',
      TOPICS_TABLE    => 't',
  )); 

Apart from the above, in the SQL error there's a left join on the phpbb_users table which neither happens in phpBB's display_forums() function nor in this extension, so it's likely that there's a conflict with another extension that adds the duplicate left joins on the phpbb_posts and phpbb_topics table.

[SalazarAG]

I will try it.

But if it can be a conflict, I think it has to do with the Topic Count (which counts the topics of users). This extension has been a problem for me while I need a lot of it.

Ah, you're right. I had a brain fart there.

the SQL error there's a left join on the phpbb_users table which neither happens in phpBB's display_forums() function nor in this extension, so it's likely that there's a conflict with another extension

I missed this. Thanks for pointing it out. I'll leave the code the way it is.

[SalazarAG]

I tried the codes and did not work!

I installed the extension in a new forum and the error did not occur. It seems to be a conflict with some other extension even. But they are many, it is difficult to find.

[kasimi]

But they are many, it is difficult to find.

Try to disable those that deal with avatars.

I disabled "Last post avatar" and the erros appears changed

Looks like there's another extension that adds t.topic_id AS forum_last_post_topic_id as well as those two duplicate left joins. Try to disable any extension that works with data from a forum's last post.

I'll leave the code the way it is.

You could try to only add the left joins if they aren't already present. I'm not sure if that's the most reliable way though.

Code: Select all

if (!$this->has_left_join($sql_ary['LEFT_JOIN'], POSTS_TABLE))
{
    $sql_ary['LEFT_JOIN'][] = array(
        'FROM'    => array(POSTS_TABLE => 'p'),
        'ON'    => 'f.forum_last_post_id = p.post_id',
    );
} 

... and the same for the TOPICS_TABLE. Here's the has_left_join() function:

Code: Select all

private function has_left_join($haystack, $needle)
{
    foreach ($haystack as $left_join)
    {
        if (isset($left_join['FROM'][$needle]))
        {
            return true;
        }
    }

    return false;
} 

[KaileyT]

Looks like there's another extension that adds t.topic_id AS forum_last_post_topic_id

That line is probably going to change. I don't think it's needed, but I need to test it out. As a matter of fact, that whole function will probably change.

Hello again!

The conflict is with the extension [pre]fixed.

I do not know how to solve, but the two extensions are useful.

[KaileyT]

I actually just pushed an update. See if it solves your problem. It's a variation of kasimi's code.

[SalazarAG]

Updated and the problem is solved!

Thank kinerity!
