Show category icons on search page (in results)

I found in listing-listview.php the relevant code for the section on the search page:

<?php
/**
* Called before the post excerpt on the listings view template.
*
* @since 1.0.0
* @param object $post The post object.
* @see ‘geodir_after_listing_post_excerpt’
*/
do_action(‘geodir_before_listing_post_excerpt’, $post); ?>
<?php echo geodir_show_listing_info(‘listing’); ?>

So the action ‘geodir_before_listing_post_excerpt’ is providing all the custom fields which per my screenshot are categories, and two text fields. However, I cannot find the PHP/HTML file that defines the action. I have manually search in all files in the geodirectory plugin folder and subfolders of functions, templates, and widgets.

I havent found the HTML code for the details page either (just the general listing-detail.php file pulling the content via actions).

do_action(‘geodir_add_page_content’, ‘before’, ‘details-page’);

Thank you Alex. I will have a fresh look tomorrow morning!

All the best for the new year!

GUUST!! You rockstar! Thank you so much!! You wont believe the time I have wasted on this!

There is only one thing left, which is to structure the icons in a meaningful way:
I have parent and subcategories. The code now shows all categories (regardless of type) next to each other, which makes sense for no sub cats but doesnt work in this case.
How would the code to be amended to have the parent categories as text underneath eachother followed by their subcatageories as icons in the same line, basically an ordered list of parent categories with their sub cats next to them?

As an example, the final output result would be:
<TEXT>Parent category name 1:</TEXT> Subcategory icon 1.1 Subcategory icon 1.2 …
<TEXT>Parent category name 2:</TEXT> Subcategory icon 2.1 Subcategory icon 2.2 …
<TEXT>Parent category name 3:</TEXT> Subcategory icon 3.1 Subcategory icon 3.1 …

Thank you again!
