Just started learning PHP and Wordpress.

Why isn't my PHP include statement working in the following header.php file?

<!DOCTYPE html>
<meta charset="<?php bloginfo('charset'); ?>" />
<?php include 'functions.php';?>
<?php if( is_page(1406)): ?>
<?php wp_title(' - ', true, 'right'); ?> <?php get_1406_page_title(); ?>
<?php else: ?>
<?php wp_title(' - ', true, 'right'); ?> <?php bloginfo('name'); ?>
<?php endif; ?> 

I need to call get_1406_page_title() which is located in the functions.php. The above code produces empty page, and when I remove the include line the title is empty.

Here is the get_1406_page_title() from functions.php:

function get_1406_page_title()
    $title = "Page title here";
    return $title;

    You do not need to include your theme's function.php - it is loaded automatically. – fischi Feb 26 '16 at 9:21
  • OK, thanks. So I should look for the problem elsewhere, maybe my get_1406_page_title(). – Danijel Feb 26 '16 at 9:24

    Enable the debug mode to find the real reason. – fuxia Feb 26 '16 at 9:30
  • You do not need wp_title(), it is a supported theme option – Pieter Goosen Feb 26 '16 at 9:33
  • Updated questions with get_1406_page_title() source. – Danijel Feb 26 '16 at 9:41

From your current code you

  • do not need to include functions.php, it is automatically done

  • Because get_1406_page_title() returns it's output, you need to echo the result from the function if you need to display the result

    echo get_1406_page_title();
  • Thanks so much. How come bloginfo('name'); doesn't require echo? It also returns a string. – Danijel Feb 26 '16 at 9:47
  • No, bloginfo() echos output, check the source. I think you are thinking about get_bloginfo() – Pieter Goosen Feb 26 '16 at 9:50
  • Ah OK... got it. I will do the same, wrap get_1406_page_title() into 1406_title() with just additional echo to make is cleaner. Thanks. – Danijel Feb 26 '16 at 10:02
  • Great idea. Good luck with your project. Enjoy ;-) – Pieter Goosen Feb 26 '16 at 10:02
