Question about dynamic data, functions, shortcodes

[APLJ1976]

I am trying out Oxygen for my wordpress website.
However current templates are heavily modified.

i have several wordpress functions i want to use like:

1. get_queried_object() to grab the current category and display a subcategory list

2. I see i can get values from ACF, but can i also reuse these values in other functions/shortcodes?

3. Custom functions such as top10_category($list); where top_10category is a custom function in a custom plugin, and $list is a return from a function getting all categories.

4. Also i have shortcodes which work with eg the postid [shortcode postid=$post_id] I cannot figure out how to get the postid in there, or as mentioned above an ACF field.

I am wondering if I can actually do above, or is it not possible for Oxygen. And if possible, is there a tutorial on how i can implement?

get_queried_object() to grab the current category and display a subcategory list

You should be able to use that in a Code Block element to get the current category and then retrieve the subcategories.

I see i can get values from ACF, but can i also reuse these values in other functions/shortcodes?

It's not possible to reuse values. You'd likely need to retrieve them in each function or shortcode.

Custom functions such as top10_category($list); where top_10category is a custom function in a custom plugin, and $list is a return from a function getting all categories.

I would expect you to be able to use this in a Code Block element or with Dynamic Data > PHP Function Return Value.

Also i have shortcodes which work with eg the postid [shortcode postid=$post_id] I cannot figure out how to get the postid in there, or as mentioned above an ACF field.

You would need to use a Code Block element with the WordPress do_shortcode() function.
