wordpress短代码仅适用于一页

Question

I wrote a shortcode that is used for displaying data and it is used just in one page (ie: PAGEX using full-width-page-template.php). The shortcode function is very huge.

function rj_mysh_shortcode() {
   // Lots of lines of business logic
}
add_shortcode('rj_mysh', 'rj_mysh_shortcode');

Every time a webpage is called I think functions.php is called and parsed by PHP. I'm looking for a solution in order to avoid to spend time in parsing something not useful.

I thought that I can create a template TEMPLATE_PAGEX and move the function there.

TEMPLATE_PAGEX.php:
<?php
    function rj_mysh_shortcode_template() {
       // Lots of lines of business logic
    }

include(locate_template('full-width-page-template.php'));
?> 

At the end the shortcode is:

function rj_mysh_shortcode() {
   return rj_mysh_shortcode_template()
}
add_shortcode('rj_mysh', 'rj_mysh_shortcode');

Is this the right solution?

You could always check what page you are on: developer.wordpress.org/reference/functions/is_page ... is_page($pageID) ... and only run the code if on that page.

function rj_mysh_shortcode() {
    if(is_page($pageID)) {
      // Lots of lines of business logic
    }
}
add_shortcode('rj_mysh', 'rj_mysh_shortcode');

or just remove the need for a shortcode, and just run the logic/code etc. directly from functions.php but doing the same page check so it only gets ran on that specific page.
