Show categories in sidebar on all pages

Question

As far as I can see, the categories in the sidebar are only shown on certain pages (Questions, Unanswered). How can I show them on all pages? I'm using a customized theme. Thanks

Answer 1

Use an advanced theme to override the sidepanel(...) function. In your version, check if $this->content['navigation']['cat'] is empty. If so it means that a category list hasn't been passed through to the theme, and you need to create one. In that case you want to set it up as follows:

global $qa_db;

$categories=qa_db_single_select($qa_db, qa_db_categories_selectspec());

$this->content['navigation']['cat']=qa_category_navigation($categories);

Then your overriding function should call the default sidepanel(...) one as usual.

Worked perfectly. Thanks

it a good solution :) :)

I don't quite get this, I've put the code above in body_content(), just before $this->sidepanel(). But it gives me an error....

The category implementation has changed in version 1.4, to support subcategories. You can try replacing qa_db_categories_selectspec() with qa_db_category_nav_selectspec(null, true) assuming you want the top level only.

I have put:
_______________________

global $qa_db;

$categories=qa_db_single_select($qa_db, qa_db_categories_selectspec());

$this->content['navigation']['cat']=qa_category_navigation($categories);

_______________________


Just before $this->sidepanel() in the function body_content().

But it gives me an error:

Warning: Invalid argument supplied for foreach() in /home/public_html/qa-include/qa-db.php on line 356

Sorry, yes, the $qa_db parameter is also no longer needed (you can remove the global declaration too).

I have put:
___________________

$categories=qa_db_single_select(qa_db_category_nav_selectspec(null, true));

$this->content['navigation']['cat']=qa_category_navigation($categories);

_________________

Just before $this->sidepanel();

And it worked now. Thank you gidgreen!
