Displaying category descriptions using custom taxonomy and cpt

    Hi,
    I try to displaying category descriptions using custom taxonomy and CPT and since I use the Divi visual builder, my idea is to retrieve it by using a shortcode inside the Code Divi Module and defining the function inside functions.php

    The problem is, I can’t make it work within the CPT environment. It just works with the normal post types and default category.

    Here the code I use:

    function wpb_catlist_desc()
{
    $catID = get_the_category();
    return category_description($catID[0]);
}
add_shortcode('cat_desc', 'wpb_catlist_desc');

    …and the shordcode for this is: [cat_desc]

    i would be grateful if someone can help me with this as i dont know what i am doing wrong and i am not PHP expert either, thanks!

    Couple things to note, if you’re in the archive for a custom taxonomy term, then you’re using the wrong functions, since those are specific for the category taxonomy.

    Perhaps something like:

    function wpb_catlist_desc()
{
    $catID = get_queried_object_id();
    return term_description( $catID );
}
add_shortcode('cat_desc', 'wpb_catlist_desc');

    This should get the current ID of the queried taxonomy term, and then pass it into the more appropriate term_description() function to return that value.

    Hi Michael,

    Thanks for your input! Yes, sounds logic and I see that it has to go in the direction you indicate, but still its strange that also with your code example, in the front-end, the box that contains the short-code is blank and I do not understand why the description does not render…

    Are you doing <?php echo do_shortcode('[cat_desc]'); ?> for that portion of it?

    Otherwise, I’d probably end up checking and confirming that get_queried_object_id() is returning the term ID you’re expecting and also extra confirming that that term has a description available. Just for some debugging intents.

    I thought that adding in functions.php at the end:

    add_shortcode('cat_desc', 'wpb_catlist_desc');

    and inside the custom post type only adding [cat_desc] ( see image: https://prnt.sc/1w4m25k ) should be enough? At least it worked for the default posts and categories.

    Ok, this is a bit different. My apologies.

    You were using almost the right function, to fetch the terms from the post being displayed, I unintentionally switched to code that would/could be used when viewing the term archive.

    Because of that, you’d want to try something like

    function wpb_catlist_desc()
{
    $terms = get_the_terms( get_the_ID(), 'artists' );
    if ( $terms ) {
        $term = $terms[0]; // Grab the first one.
        return term_description( $term->term_id );
    }
    return '';
}
add_shortcode('cat_desc', 'wpb_catlist_desc');

    Make sure to change ‘artists’ to your actual taxonomy slug.
