# Inline PHP vs functions.php

 *  Resolved [lemaxim](https://wordpress.org/support/users/lemaxim/)

 * When I put
    `<?php echo get_the_title($post->post_parent) ?>` into my theme template
   the output is correct.
 * However, if I try to put it into a function and then call it from functions.php
   it does not work. Are there some sort of global variables that I should be calling?
 * I’m trying to use this with conditional parameters in the functions.php file 
   because the template itself would get quite bloated if I had it inline.
 * Thanks in advance for any help!

 * Should be obvious, no? You are directly using the global variable $post (you’re
   trying to access the $post->post_parent variable). So you need to put `global
   $post;` at the top of your function.
 *     ```
       function whatever()
       {
       global $post;
       echo get_the_title($post->post_parent);
       ...
       ```
