I’m using the classic editor and have disabled Gutenberg blocks and global styles.

I’ve created a custom post type named Resources, for which I’ve also created an archive archive-resources.php.

I’ve created a Taxonomy Custom Field labeled Resource Type (name: res_type), which is linked to Resources and has a Radio Button appearance.

I’ve created a Taxonomy for my custom post type and custom field labeled Materials (the three options for materials are “Book,” “Course,” and “eBook”).

In my archive file, I’ve started the loop if ( have_posts() ) : while ( have_posts() ) : the_post();, and in the loop, I am trying to display which Material was selected from the Taxonomy Custom Field in the Resource that was created.

Initially, I was trying to use the following code:

$res_type = get_field('res_type'); 

if ($res_type) {

echo '<h4 class="open-sans-lite resource-subtitle smaller-text">'.esc_html($res_type).'</h4>';
}

This code doesn’t work because if my Taxonomy Custom Field “Return Value” is set to ID, it only returns a number, and if it’s set to Object, it returns an error ("fatal error/exception").

Then, I tried this code:

$res_type = get_field('res_type'); 

if ($res_type) {

echo '<h4 class="open-sans-lite resource-subtitle smaller-text">'.esc_html($res_type->name).'</h4>';
}

However, this resulted in nothing at all in my HTML, not even an empty H4 element.

I’ve also been trying get_field_object() to no avail.

Please help me understand how to retrieve the “Book,” “eBook,” or “Course” taxonomy that’s selected for their respective Resource from the Taxonomy Custom Field in the loop.
