how to get arguments from action hooks

  • 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
