Utilizing my function as a shortcode and PHP function. (add_action/do_action help?)

[ad_1]

New to WordPress development.

I have a function that returns an HTML table of usernames and IDs. I’ve successfully registered it as a shortcode with defaults.

I’m curious how to properly register it as a function that can be used in my other theme files. Would also like to see an example of passing arguments to `user_ID_list` elsewhere in the file. I’m guessing I need to utilize `add_action` and `do_action`, I’m but having trouble wrapping my head around how they work.

Trying to learn best practices on how to accomplish this.

Here’s the code – [https://gist.github.com/AakLak/26cc05d01f66af0c09dacab895a9c295])

Thanks!

Edit:`if ( shortcode_exists( ‘list_users’ )) {echo ‘Hello?’;}`This doesn’t echo anything. However the shortcode works when used in pages.

Edit:

I solved it by changing:

`function user_list_shortcodes_init(){add_shortcode( ‘list_users’, ‘user_ID_list’ );}add_action(‘init’, ‘user_list_shortcodes_init’);`

To just the `add_shortcode` line. I’ll have to look into the quirks about this, I’m guessing this caused things to load in an incorrect order.
