Is it possible to create a new action hook like do_action('my-hook-name'); inside a call to add_action();?

I'm aware this code doesn't work, but I was thinking something along the lines of... add_action('init', do_action('my-hook-name'));

or

Is the only way to actually add a callback function to init, then inside my callback function create my hook?

add_action('init', 'my_callback');
function my_callback(){
    do_action('my-hook-name');
}

    Yes, it's possible. What's the use-case, though? Why not just fire on the existing action you hook into? Nov 13, 2013 at 18:53
  • Creating a plugin which hooks into theme hooks. Looking to provide plugin hooks to the theme hooks. It's not a big deal to actually create a callback, just thought it would be nice to have shorter code. Nov 13, 2013 at 18:55
  • Out of curiosity, does it work for you? I mean, the second parameter is supposed to be a callback (just asking, for I get an error) Nov 13, 2013 at 19:07

    In such a case, anonymous function should do the magic add_action('init', (function(){do_action('i_am_a_hook');})); Nov 13, 2013 at 19:35

    And anonymous functions in hook calls are not user- or child-theme friendly. Nov 13, 2013 at 19:49

Creating an answer based upon responses via comments on original question of: Is it possible to create an action hook using do_action() within add_action()?

Yes it is possible to create an action hook using do_action() on a call to add_action().

For clarification, the following code does NOT work:

add_action('init', do_action('my-hook-name'));

As stated by @IvanHanák in the comments to the original question asked; It is possible to create an action hook using do_action() on a call to add_action() by using anonymous functions.

An example of creating an action hook using do_action() on a call to add_action() using anonymous functions:

add_action('some-existing-hook-name', function(){do_action('my-new-hook-name');});

However, it should be noted that using anonymous functions can make it difficult to debug or remove hooks.
