   so I'm reading that action hooks pass arguments to the function that you hook to the action, but how does it happen? I mean how do I access the argument in my function?

   this code doesn't get it

   function remove_post_dir($post_ID) {
     if(file_exists(ABSPATH. '/wp-content/uploads/'. $post_ID)) {
       rmdir(ABSPATH. '/wp-content/uploads/'. $post_ID);
     }
   }
   
   add_action( 'delete_post', remove_post_dir($post_ID));

   I used a bad example for add_action, it should be like this:

   add_action( 'delete_post', 'remove_post_dir');

   There's nothing wrong with your code there, as such. Try this for example:

   function remove_post_dir($post_ID) {
   echo "I JUST GOT $post_ID";
   }
   add_action('delete_post','remove_post_dir');

   That will work fine. The default setting is to receive 1 argument.

   If you wanted to be explicit, you could use:
   add_action('delete_post','remove_post_dir',10,1);
   which tells it that you have priority 10 and want to receive 1 argument.

   problem was my function wasn't in quotes, and had the parentheses like a regular function call, I copied that style out of an older plugin
