Question

I have included header.php and index.php on the same page.

The following can be found on the header.php file:

<?php 
    $pageName="home";
    if(is_page('47')){
       $pageName="services";}
    printVar($pageName);
?>

function printVar($v){ //on functions.php
    echo $v;
}

It prints out the var immediately after the if-statement and anywhere on header.php, but when I go to index.php it doesn’t print.

<ul class="<?php printVar($pageName); //does not print out ?>">  
    <li class="home"><a href="/">Home</a></li>
    <li class="services"><a href="/">Services</a></li>
    <li class="seminar"><a href="#">Seminar</a></li>
    <li class="contact last"><a href="#">Contact</a></li>
</ul>

How can I print this variable without moving everything to index.php?

Answer 1

you need to have

<?php get_header(); ?>

in your index.php file
