Kunena 6.2.5 & module Kunena Latest 6.0.7 released

The Kunena team has announce the arrival of Kunena 6.2.5 [K 6.2.5] which is now available for download as a native Joomla extension for J! 4.3.x/4.4.x/5.0.x. This version addresses most of the issues that were discovered in K 6.1 / K 6.2 and issues discovered during the last development stages of K 6.2

This category contains miscellaneous, uncategorised user contributions, (templates, modules, plugins and hacks) relating to older versions of Kunena that are no longer supported.

The topics in this category are for historical interest only. Owing to the structural changes that occurred in K 2.0, many of the ideas in these topics will not work with later versions and, for that reason, the topics are locked.

Hi,

I had to convert some Topics and Messages from Agora to Kunena, but there's nearly nothing :-)
I decided to write a little PHP file for converting everything I need for myself.

Now I would like to share my work with the community. Maybe some users would complete it to a fully functional Converter.


First of all, synchronize the Joomla-Users.
Then you have to create the categories and subcategories lige in your Agora-Forum.
Follow the instructions in the code to link forums to categories
Upload the saved php-file to your webspace and open it in your browser.
After everything is done, recount statistics under Kunena-Tools

Happy converting :-)
regards
Roman

!!! Updated Version - 0.2 !!!

Changes:
- add functionality to import agora-categories and forums with standard permissions
- automattically maps new category-id with old agora forum id

Convertion-Steps:
First of all, synchronize the Joomla-Users.
Upload the saved php-file to your webspace and open it in your browser.
After everything is done, press "recount statistics" under Kunena-Tools

Hey, thanks for a great script. However there is a problem with it:

Agora uses Categories, and each category can have many Forums (jos_agora_category and jos_agora_forum MySQL tables). However, Kunena only uses categories (j25_kunena_category MySQL table) and on line 36 you are inserting all jos_agora_category to j25_kunena_category, but on line 81 you also insert jos_agora_forum into j25_kunena_category, which for me at least results in an error "Duplicate entry '6' for key 'PRIMARY'" , because forums and categories have separate ID's on Agora.

I am not sure if this is the way it is supposed to work (insert categories and forums into categories). In Agora every Category has an ID, and every forum has a foreign_key called cat_id which points to the Category it belongs. How do categories and subcategories work in kunena?

In my Agora forum I have 5 Categories with IDs 1-5, and 15 Forums with IDs 2-16, and I get an error about a duplicate entry primary key with ID of 6. So each of the subcategories is supposed to have a parent_id of the agora category. It seems like the Category ID is not incrementing near line 81 for the next iteration, so it tries to create a new category with the same ID as the previous category.

So, basically at lines 46-49 you are counting how many categories there are and you assume they have the same id, but you should instead check for the largest ID. My forums got IDs from 2-6 for some reason, which broke everything.

Here is my code to replace lines 46-49, so that it reads the max id from the current categories and sets it as cat_mod_id (replace the code from line 46):
Code:
$sqlnum = "SELECT * FROM jos_agora_categories"; $resnum = mysql_query($sqlnum); $rows = mysql_num_rows($resnum); $maxidquery = "SELECT id FROM jos_agora_categories ORDER BY id DESC LIMIT 0,1"; $resmax = mysql_query($maxidquery); $resmaxid = mysql_fetch_array($resmax); $maxid = $resmaxid['id']; $cat_mod_id=$maxid+1;

If you want to, you can also check if $rows is different than $max_id and then decide which one to use, however I think you really need to know the actual maximum category id since it is AUTO_INCREMENT as well, and having a duplicate key will break things!

--EDIT--
So here is my version of the code with my fix implemented:
