There is an inbuilt function for returning null: __return_null.
So you can replace create_function('$a', 'return null;'); with just '__return_null' (note the quotes) as it seems $a is not used anyway.
Or you can use an anonymous function as the argument directly: function($a) {return null;} (no quotes). Either way since the argument is expecting a ...

You should be able to change create_function( '$a', "return null;" ) to Anonymous Function (aka Closure) :
From :
add_theme_page(
$this->args['page_slug'],
__('Dev Mode Info', 'nhp-opts'),
__('Dev Mode Info', 'nhp-opts'),
$this->args['page_cap'],
$this->args['page_slug'].'&tab=...

Say that get_author_posts_url(1) return the following URL
https://example.com/author/admin/
Passing the $author_nicename will change this. So get_author_posts_url(1, 'foo') will result in

$file_contents = ...

My include has a handful of custom hooks which handle enqueuing, dequeuing and inserting custom HTML.
I'm still not 100% certain what you mean, but if this code is normal WordPress code, with functions and add_action(), and you only want those hooks to run on these events pages, then the proper way to do this would be to include that file into your theme's ...

add_action( 'woocommerce_single_product_summary','content_after_addtocart_button' );
function content_after_addtocart_button() {
global $product;
$product_title = $product->get_name();
$product_price = $product->get_price();
echo '<div class="content-section">

has_category() only tells you if a specific post has a given category (or any category, if none is provided). You can tell it which post to check by passing the post ID as the second argument. When used inside the loop however, you can omit the post ID and it will check the current post.
