Wordpress Plugin: Category Converter
Version Number Update: 1.4 (2/2/07)
Incompatible with Wordpress 2.3: old category table.1 Possibly incompatible: upgrade-functions.php.
*** NOTE: Category Converter compatible with mysql server versions 4.0 and greater ***
When you begin blogging, you think about the types of genres you want to write about…what interests you…but over time those ideas change and you branch out. Well if you established categories in your blog when you first started, those might not be what you are blogging about any more. What about if you wanted to condense categories, it is very time consuming.
I have been in that situation where I wanted to condense my 25 categories into 7-10 categories. Up until now, there were no tools to help you accomplish this goal.
I decided to write a Wordpress plugin Called: Category Converter
Downloaded a total of 3675 times
Category Converter Features:
- Condense wordpress categories
- Rename categories
- Add categories
- Delete moved categories
Installation:
1. Download the Category Converter Plugin
2. Unzip the file and put category_converter.php into wp-content/plugins/
3. Click on the Plugins tab in the Admin panel and activate the Category Converter plugin.
Useage:
1. After the plugin is activated, click on “Go To Plugin” to use it. (Also in Options tab under Category Converter)
2. Under the category that you would like to move, click “move to”
3. Choose the category you would like to move to and then hit submit
4. Enjoy!!

I have WP 2.1 installed and I tested it on that install. I will check it out again to see if it works. Sorry about that

Is the compatibility problem with WP2 sorted out? Reads like a really useful plugin, that one.
Posted: Feb 1st, 2007 at 9:40 am
I have had quite a few people use it and the only person who had a problem with it was the one who commented here earlier. Try running it and let me know if it works or if it doesn’t

Hi
I haven’t tested it but ..
if I rename a category whats going one with the links to this old category
does this plugin sent an redirect 301 to the new name of the category
I hope you understand my meanings
regards
Monika

If you rename a category, it will just send you to the new category. It does not check by name, it will check by category_id. When you use the plugin, the posts in the category will get moved to the new one and delete the old category. It will not mess up your categories unless you have people going to the category directly after it doesn’t exist anymore.
I hope this helps, but let me know what you think after you try it

Thanks Timothy, I can;t thank you enough for this plugin. It’s really helped me with “housekeeping” and I’ve reviewed it (allbeit briefly) on my website. Cheers mate!
Posted: Feb 1st, 2007 at 1:12 pm
quick question: I am running the latest version, WP “ELLA”. I had to deactivate the plugin for my blog to be visible, is this part of the functionality, to hide the blog while the categories are being shifted/reassigned?
Posted: Feb 1st, 2007 at 1:34 pm
Ok, so I figured out what the problem with the plugin and I have fixed it in the new version. However, if you would like the code quick fix, remove lines 2 & 3 of the plugin and it should work much better. I would recommend just downloading it again for those who do not know code. Sorry about the problem and I am glad that you enjoy the plugin
Posted: Feb 1st, 2007 at 2:26 pm
Thanks T-bone, this rocks. I will backup my files and give it a whirl
Posted: Feb 1st, 2007 at 2:38 pm
I commented out lines 2 & 3 as per:
// session_start();
// ob_start();
I got this nasty error:
Warning: Cannot modify header information - headers already sent by (output started at /home/nostatus/public_html/wp-content/plugins/category_converter.php:174) in /home/nostatus/public_html/wp-includes/pluggable.php on line 275
I am sticky to the activating and cleaning house then deactivating the plugin, this works for me. I also downloaded the new ZIP but it had the same code. Sorry to be a pain Tim!
Posted: Feb 1st, 2007 at 2:46 pm
Timothy: I’d like to email you the error I got after converting a category, but I don’t see any contact information. Can you put a contact page up? I’ve downloaded the plugin today, so I’m going by version 1.1. (You might want to add that into this post.)
Thanks!

As far as I know, all bugs are fixed - Timothy

Tim-
I installed this on my blog today in order to move some posts that were in several different categories into a new category. Only problem is, some of the posts that are going into one category are a subset of other categories. In other words, I am creating a new ‘McAfee Issues’ category, but the articles I want to move into that category are in several cats now (’PC Tips,’ ‘MSI Development,’ etc.), but there are also unrelated articles in those categories. I would love it if the next version of your plugin featured a way to search for a particular term or tag on the blog, then move all post results into the new category. That would be a huge help for me, as I can’t think of a good way to do it manually, and I’m sure there are a bunch of people out there who’d like to do the very same thing. Great start on the plugin, btw.

I downloaded the plugin ( Version: 1.4 Version Updated: 2/2/07 per the header in the php file)
and installed it in WP 2.0.5, running on Windows+Apache+MySQL 5.
I tried to move one category and I got the following errror message
Warning: Cannot modify header information - headers already sent by
(output started at c:\weblog\wp-admin\admin-header.php:16)
in c:\weblog\wp-content\plugins\category_converter.php on line 127
But it seems to have worked.
Posted: May 25th, 2007 at 4:32 pm
I tested this plugin today, but is it just me, or does it leave all of the old pages as 404 errors. That means that if you have any search engine traffic to those pages, all the visitors will end up in 404 errors. Not the plugins fault, just the way Wordpress works.
The categories will work fine, but if any of the posts you’re moving are indexed in the search engines you’re going to lose all of the traffic to them at least until they are re-indexed.

I tried today, with WP 2.2, and I moved a few categories, but the articles didn’t move ….. I move from category extensios (2 articles) to firefox (2 articles). Now firefox shows 4 articles, but when I go there there are only 2 !!!. The other two articles are gone apparently …..

@normanski
Yea, I have been trying to find to work on it since it is a little more complicated than just changing the table names. Things have been a little hectic with work and family things and I have not been working on it as much as I would like. As soon as I get it fixed, I will update this post and send you an email letting you know that it is working. Thanks for your patience.

I agree this article is very helpful.
I have been reading about how to improve mt article writing,

According to Dell the reason for the delay was the drivers weren’t ready and their app which helps automate the installation process was not ready. Google it and you’ll find the stories
