Ok, as we had the pleasure before with Your question
http://www.question2answer.org/qa/20735/i-want-to-see-categories-only-on-home-page-how-can-i-do-it
we can go ahead with the modification to achieve that the category description gets printed out in Your sidepanel when You are on a category page.
In admin menu You can add a description to each category, I think it is up to 1000 characters. The way I am using here is the best I found, it still may be that there are better ways to solve it, but this is the best I can offer for now.
Now please modify and add the sidepanel function in Your qa-theme.php as follows just before the closing }
function sidepanel()
{
$this->output('<DIV CLASS="qa-sidepanel">');
$this->widgets('side', 'top');
$this->sidebar();
$this->widgets('side', 'high');
if (qa_request_part(0)==''){
$this->nav('cat', 1);
}else{
if ( (isset($this->content['categoryids'])) && (!empty($this->content['categoryids'])) && ($this->template=='qa')){
$mycategoryid = end($this->content['categoryids']);
$mycatgeorycontentholen = qa_db_query_sub("SELECT content FROM ^categories WHERE categoryid = '$mycategoryid' ");
$mycatgeorycontent = qa_db_read_one_value($mycatgeorycontentholen,true);
$this->output($mycatgeorycontent);
}
}
$this->widgets('side', 'low');
$this->output_raw(@$this->content['sidepanel']);
$this->feed();
$this->widgets('side', 'bottom');
$this->output('</DIV>', '');
}
That should do it. New readers please read the question mentioned above as well.
