    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?

  • 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?
