Use of post date and categories

Sure, it’s possible to create a custom template by following these instructions:

Hi,
Thank you for the fast reply!

I want to add a function to class-wprm-recipe.php in order to get the post categories ( like $recipe->categories ), but I don’t want to change the plugin code.
Should I add it to my child theme functions.php or do I have to replicate some of the plugin’s code structure.

Is there a reason for it needing to be a part of the recipe object?

My reason is that I have already in place an architecture where the categories have assigned to the parent post, not the recipe itself (like cousine)

Anyway, I think I can use something like

$category_detail=get_the_category($recipe->parent_post_id());
foreach($category_detail as $cd){
echo $cd->cat_name . ' - ';
}

inside the template php file.
