If the theme I used is no sidebar defined, when I checked in presentation – widget, is there any way to configure it manually in the code of the template? There’s eventually a sidebar but it didn’t show up in presentation widget somehow. So the only way to do it is to configure in the code manually.

Hey,

Thanks for considering.
To not complicate things, just entering a string of comma separated category ID’s should do the trick. Perhaps, not the user friendliest solution, but some similar plugins like breukies category widget worked like that before it got broke with newer wordpress versions.

Then a new text input field for the id string should be all that’s needed to the form, and then add the string to the argument array. I’m not much of a php wiz, but I made a quick personal mod to your script where I just hardcoded in some categories at the end of the array to exlude. Adding: ‘exclude’ => ’52,73′ to the end. Works perfect, but a bit tedious to update with new categories.

I’ll keep my eyes open if you decided to include it.

How can I add this widget more than once to the sidebar?
I want to create different parts in the sidebar with different categories displayed, similar what flexipages does with pages. Under Available Widgets is “Extended Categories 1″ and the Add link. When I add the widget, the Add link disappear. It looked for me (because if the “1″), I could add more than one…

  The dropdown itself is created by WordPress itself. So if you change the CSS your theme applies it could change, but it probably will change for all dropdown boxes.

Hello Peter:

I tried to install your plugin via WP’s “Add Plugin” functionality, using WP 2.8, directly from the WP plugins site.

During the install process, I get the error:
Incompatible archive PCLZIP_ERR_BAD_FORMAT (-10) : Invalid archive structure

When I download the ZIP file from your site, and upload it to the WP Installer, everything works fine. You might want to look at the package on the WP servers.

Hi Peter,
I’m using your plugin in my blog and it works great. In case of the rss icon there is a little problem I can’t solve. Maybe you can help me with it. On my right sidebar at http://www.babbel-net.com/ you can see under “Team” or “Blog abonnieren” that I centered the rss icons cause it just looks better. I did it with this sort of code:

style=”border: none; margin: 0 0 -4px 0; padding: 0;”

My question is now how can I reach the same effect in your plugin so that the rss icons under “Kategorien” lay on the same centered position like the others?

Greetings from germany and thanks in advance!

P.S. I’m using wordpress since two days and the whole coding thing is totally new for me. So I hope my question isn’t too silly.

  You will have to edit the style.css

  I do believe that should do the trick

        Another question – is the load time longer similar to that of Ajax (i.e. does it load as needed)?
        I have 100 categories which I would like to divide among about 6 sets. Will my load time be long?
        Thanks so much again!

August 19, 2009 at 7:40 am
Nicole,

Search engine spiders can’t fill out forms or pull down on lists, so content that is only accessible through pull-down lists will not be indexed.

It’s not loaded as needed. All lists are populated before the content is served. The load time depends on the server the site is running on. I can’t imagine the load time would increase much by implementing your idea.

Hi Peter, thanks for your quick reply. In answer… no the built-in categories widget is not there at all, it makes no difference if the Extended categories widget is active or deactivated. I wonder if it’s also something to do with a theme I used – the Hybrid theme (and child themes)? I’ll post on their forum and see if it might be something to do with the theme (which I’m no longer using) as well.

Hi Peter. I use the plugin on my site.
I replace all my categories menus with your pluggin, just for the ease of customisation

I was wondering if the option to “nofollow” certain category links would be a good idea in a future release?
The category widget is usefull to sort posts by differnt category parameters, but this may produce a lot of links that you might not want the serch engines to waste their time spidering duplicate content.

If i was building a site by hand i might nofollow these links, so i thought i’d as you opinion

  If it would be for all categories it would not be a big problem but to only add nofollow to certain categories would mean a bit more programming, I don’t think it’s impossible though. I might implement it in a future release. I have a few other things in the pipeline right now.

Great category plugin … Couldn’t live without it now that i’m used to it … I have a suggestion, so, for a feature that could make it even useful. Why didn’t you propose the “order by slug” feature ? Ordering by slug is an easy way to order your categories the way you want without acrobatic moves. For those who are not too “SEO touchy”, you just modify your slugs to get the order you want when listing categories …
Thanks for this fine plugin.

Any chance of a future update or sharing code that we can add that would bold the high level parent categories? It would make them stand out much better as compared to the child categories. Great plugin either way. Thanks!

Your most recent upgrade has locked me out of my admin, so had to delete the plugin through cPanel. As soon as i clicked automatic upgrade the page reloaded with a blank page and i couldn’t get back into admin.

Hope you can take a look, thanks

Same problem as Bill and Art – when doing the automatic upgrade in my wp-admin, it looked me out and gave me this error:
Fatal error: Call to undefined function add_meta_box() in xxxxx/wp-content/plugins/extended-categories-widget/2.8/class/avh-ec.admin.php on line 42

Had to delete the plugin via FTP in order to regain access to my admin panel.

Beware: it seems to be in conflict with wp-Super Cache. I have WP 2.9.1 and AVH Extended Categories 2.8 works perfectly. When upgrading to 3.0 no way to access my dashboard.
Without wp-Super Cache, I got this FATAL ERROR : Call to undefined function add_meta_box()

If you get : Fatal error: Call to undefined function add_meta_box()

Please upgrade to version 3.0.1 it’s available on the WordPress site.

You can just install this new version and everything should be fine again, as far as I know you shouldn’t even have lost your widget settings.

Thanks for the nice plug-in. I have a fw questions.

2) Is it possible to link RSS to Feedburner feeds instead of the default WordPress feed?
Thank you for your help.

  1. No, it’s either all categories or none.
  2. Currently it is not possible. If you want it it would mean you have to setup a Feedburner feed for every category. I would have to look into what it would take to program this option.

  Please make sure you don’t have to the option Selected Categories selected. You can’t have hierarchy with this option (you could select children but not the parent and you can’t show hierarchy)
  There was a bug in the previous version of AVH Extended Categories which made it work anyway.

  You sure can.
  
  You’ll have to create 4 groups, each containing the categories you want to show.
  Edit the pages and select the desired group of categories you want to show.
  Activate the Categories Group widget in the sidebar and you are set.

I want you to notice that when using this plugin in a multilingual site using WPML only categories are shown in the default language, not the secondary ones.

I hope ypu consider fix these feature soon. Thank you!

Great plugin!! Thank you!
Wondering if next update could add a “sort by slug” and “font style bold for fist level”. That would be perfect then!!

Reply
- Peter
  April 7, 2010 at 8:28 am
  You should be able to display the font style bold for 1st level in AVH Extended Categories by adding some css:
  
  .widget_extended-categories ul li { font-weight:bold; } .widget_extended-categories ul li ul li { font-weight:normal; }
  
  You can add the CSS to the file avh-ec.widget.css
  Take note that next time an update is installed of the AVH Extended Categories plugin these changes will be gone due to the way WordPress updates plugins. I’m working on a solution for this.

    Wow, how fast and how kind you are, Peter! Thank you for your reply, I’ll try this right away. Please also consider the “sort by slug” function because sometimes we need to organize the categories display in our own order, not by name or by count, and we cannot control the ID. So the easiest way I can think of is sort by slug. Thank you again!

I was wondering if anybody know hows to modify the existing category widget to only display the categories within the selected parent category.

Example:

If my categories are structured like:

-Computers
– Laptops
– Desktops
– Software
-Electronics
– Cameras
– Audio/Video

If a somebody is viewing posts in the Computers category I would like the categories widget in the side bar to only display Laptops, Desktops & Software..

Is there a way to get this done? Can this plugin do that?
Thanks!

Reply
- Peter
  October 24, 2010 at 11:53 pm
  It can be done but not automatically. You can create category groups and assign a group to a post.
  For example: You would create a group called Computer_Group, add all Computer related categories to the group and assign the group Computer_Group to a post.
  
  I’m sure I could create a widget that could do this automatically but unfortunately I’m short on time, if you want to discuss this further please use the forums.

(I tried to post this on your support forum but your validation question is broken. Unless 32*0 is not equal to 0..? I have no idea what the correct answer is, I’ve given up.)

There is a bug in AVH that causes a fatal crash with WordPress 3.1 with WP SuperCache enabled.

the offending line is this:
$pluginname = plugin_basename(trim($plugin));

i fixed it by changing it to this:
$pluginname = “extended-categories-widget”;

The reason I suspect is something to do with the global variable $plugin is not as expected when you are looking at a cached page. It causes this fatal error:

Fatal error: require() [function.require]: Failed opening required ‘/wordpress/wp-content/plugins/wp-super-cache/2.8/avh-ec.client.php’ in /wordpress/wp-content/plugins/extended-categories-widget/widget_extended_categories.php on line 45

Can you show the links to the blogs under the category so that user can select the blog they want to see instead of showing all the blog contents in one page one after the other for that category? I see almost every body has these blog links underneath the category and i have not yet found a plugin for that.
