WordPress hook inside another hook

wphook.php

/*
To use one hook inside another hook in WordPress, you can simply add the second hook as a callback function to the first hook
For example, let's say you want to add a custom function to the init hook, which in turn uses the wp_enqueue_scripts 
hook to enqueue some scripts. You can do it like this:
*/

<?php
function my_init_function() {
    // do some initialization here
    add_action( 'wp_enqueue_scripts', 'my_enqueue_scripts_function' );
}

function my_enqueue_scripts_function() {
    // enqueue your scripts here
    wp_enqueue_script( 'my-script', 'path/to/my/script.js', array(), '1.0', true );
}

add_action( 'init', 'my_init_function' );

/*
In the above example, my_init_function() is added as a callback function to the init hook. 
Inside this function, the add_action() function is used to add my_enqueue_scripts_function() as a callback 
to the wp_enqueue_scripts hook. This means that when the init hook is fired, both my_init_function() 
and my_enqueue_scripts_function() will be executed.
You can use this same pattern to add any hook inside another hook in WordPress. 
Simply define your function, add it as a callback to the first hook, and use add_action() or add_filter() 
to add any other hooks that you need inside your function.
