   I've been tinkering with the template tags, but I don't see a way to do this...

   I have PHP execution enabled in static pages (using a plugin). What I would like to do is automatically generate the content of the page where you have something like this

   Name_of_Categoy_#1 <-- this is a link
   Description_of_Category_#1
   Name_of_Categoy_#2 <-- this is a link
   Description_of_Category_#2
   Name_of_Categoy_#2 <-- this is a link
   Description_of_Category_#2

   Listing a list of names which are links is dead simple - there are built in template tags that do that - but how about extracting and interleaving the stored description of the category?

   See if this is of any help: http://codex.wordpress.org/Template_Tags/category_description

   Kind of - save that the category_description(category) function takes the ID of the category as a parameter - and I don't have those :)

   The closest useful function I can find is get_the_category() - which returns an array of arrays of data elements about a category, one for each category that a POST IN THE LOOP belongs to. THAT I could pull apart and format out into the kind of list I want - BUT what I want is not the categories belonging to any one post, but a universal list off all categories belonging to the Blog - sort of a Category index with built in descriptions - automatically generated.

   Title/Link
   Description

   Title/Link
   Description

   etc.

   Here we go - a nice little code snippet I came up with, dropeed into a page with the RunPHP plugin active for the page.

   
<?php
global $wpdb ;
$results = $wpdb->get_results("SELECT * FROM " . $wpdb->categories);
if ($results)
{
echo "<dl class=\"catdeflist\">n";
foreach ($results as $row)
{
echo "<dt class=\"catdeflist_name\"><a href=\"/?cat=". $row->cat_ID . "\">". $row->cat_name . "</a></dt>n";
echo "<dd class=\"catdeflist_desc\">". $row->category_description . "</dd>n";
}
echo "<dl>n";
}
else
{
echo "<p>There are no categories defined on this blog.</p>/n";
}
?>


   It's even CSS styled. You can define 3 classes in your theme

   catdeflist - the definition list which holds all definitions and descriptions

   catdeflist_name - the '<dt></dt>' container which holds the name of the category.

   catdeflist_desc - the '<dd></dd>' container which holds the decription text of the category.

   Hmm.. I'm actually quite surprised to not find a function that gives you an array of category objects based on what you specify. I guess I'll have to make a function based on wp_list_cats() and just return the category array.

   Thanks wyrd! I've read it, and it was really useful.

   Is there a way Charles to use function include so you can list only certain categories with description under?
