How to integrate an additional piece into a piece of code correctly?

Question

PHP

There is this piece of code

if( ! function_exists( 'woodmart_after_add_to_cart_area' ) ) {
  function woodmart_after_add_to_cart_area(){
    $content = woodmart_get_opt( 'content_after_add_to_cart' );
    if ( empty( $content ) ) return;
    echo '<div class="woodmart-after-add-to-cart">' . do_shortcode( $content ) .  '</div>' ;

  
  }
  add_action( 'woocommerce_single_product_summary', 'woodmart_after_add_to_cart_area', 31 );
}

And before DIVa, you need to insert the output here is this piece.

$my_lang = pll_current_language();  
 if ( $my_lang == 'en' ) {
    echo do_shortcode ('[html_block id="3455"]');
} elseif ( $my_lang == 'uk' ) {
    echo do_shortcode ('[html_block id="4730"]');
} else {
    echo do_shortcode('[html_block id="4725"]');
}

In WordPress, there is no such thing as "correct", since everything that moves more or less is recognized as the right decision. Therefore, bothering with codestyle, correctness, maintainability, and at least an elementary division into code, data, and presentation in the wordpress environment is considered bad manners. The only thing to take care of is that the length of the name of each next written function must be greater than the previous one. This is due to the fact that in theory each next function describes a more complex functional than the previous one, and possibly contains all the previous ones. In this case, as a name, you can simply combine all the names of the functions used through underscores. Otherwise, you are free to freestyle.
