Maybe after each topic we could show 3-5 related topics...this would increase stickiness of forum and user engagement. A bit like Wordpress's related posts plugin.

We have a plugin for this here:
https://github.com/evnix/codo_similar_topics

awesome...downloading now

@adesh1414127033 on install

got this

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<> 69 AND p.post_id = t.post_id AND EXISTS (SELECT 1 FROM codo_permissions AS p' at line 1' in /home/sites/#####.co.uk/public_html/sys/CODOF/Search/Search.php:191 Stack trace: #0 /home/sites/######.co.uk/public_html/sys/CODOF/Search/Search.php(191): PDO->prepare('SELECT p.post_...') #1 /home/sites/#####.co.uk/public_html/sites/default/plugins/codo_similar_topics/codo_similar_topics.php(55): CODOF\Search\Search->search() #2 [internal function]: plg_similar_topics->get_similar_topics(Array, Array) #3 /home/sites/####.co.uk/public_html/sys/CODOF/Hook.php(65): call_user_func_array(Array, Array) #4 /home/sites/#####.co.uk/public_html/sys/Controller/forum.php(431): CODOF\Hook::call('on_topic_view', Array) #5 /home/ in /home/sites/####.co.uk/public_html/sys/CODOF/Search/Search.php on line 191

Make this change

Open sites/default/plugins/codo_similar_topics/codo_similar_topics.php

On line 52,

replace

$search->tid = '<> ' . $info[0]['topic_id'];

with

$search->tid = '!= ' . $info[0]['topic_id'];

@admin thank you

Will we see this plugin in the next version of codoforum or will this be optional?

This is optional, we didn't make any repository for plugins otherwise we would have added it there.

Ah ok @admin and I see oh my gosh: Codoforum 4.0!

@admin thanks for updating plugin at GitHub

@admin is there a way to change the sensitivity of the "relatedness" as at moment the topics the plugin is showing don't look related enough...

Hi @adesh1414127033 , @hard_as_snails , @RolluS

I download the plugin from https://github.com/evnix/codo_similar_topics. However, after installing the plugin as the guildeline, I can see anything in the side bar. I'm using codo 3.3.1.

I add some commnet into the codo_similar_topics.php for tracking. Should I edit any other things?

<?php

/*
 * @CODOLICENSE

echo "Begin test codo similar topic.";
echo "<br />";

defined('IN_CODOF') or die();

class plg_similar_topics{

    function get_similar_topics($info){



            require 'common_words.php';
            $common_words = plg_get_common_words();


            $search = new \CODOF\Search\Search();
            $title=$info[0]['title'];

            //replace double spaces with single space
            $title = str_replace("  ", " ",$title);

            //get all the words in an array
            $words=explode(" ",$title);

            //remove the common words
            $tarray= array_diff($words, $common_words);

            //join the new array
            $title=implode(" OR ", $tarray);            

            $search->str=$title;
            $search->tid = '!= ' . $info[0]['topic_id'];
            $search->pid = '= t.post_id';

            $links=$this->generate_links($search->search());

echo "End test codo similar topic.";

Can't see any similar posts, except my comments.

I'm using codo 3.3.1.

The current version is 3.5, it's time for an update.

@James7 Probably better for him to wait until the bugs in 3.5 have been sorted first. There have been a couple that would cause issues atm. I have stayed with 3.4 myself atm until the bugs are fixed or 3.5.1 with the bugs fixed is released (preferably).

Thank you @James7 and @RonAus !

It works on the 3.4 B19 beta verion. I'm waiting for 3.5.x official release.
