How to pass multiple parameter in add_action()

Question

I have below code.

add_action( 'admin_init', [$this, 'settings_page_registration'] );

I would like to use enqueue_assets function name inside add_action().

Should I use like below ?

add_action( 'admin_init', [$this, 'settings_page_registration', 'enqueue_assets'] );

No, that's not how it works. What are you trying to do? Why do you need to pass the function name like that? — Jacob Peattie, May 10, 2022 at 3:39
Thanks @JacobPeattie. I would like to call the function at admin_init. Thanks. — Foysal, May 10, 2022 at 3:53

If you need to call enqueue_assets at admin_init, then add a new add_action():

add_action( 'admin_init', [$this, 'settings_page_registration'] );
add_action( 'admin_init', [$this, 'enqueue_assets'] );

That said, if your assets are JS scripts or CSS, you should consider wp_enqueue_script() & wp_enqueue_scripts

This is the correct approach. One advantage of this method that I would like to point out is that, when each function is added separately, each function can later be removed independently by using remove_action, if ever needed.
