WordPress as CMS and PHP
If you’re using WordPress as a CMS and doing some extra coding - for example picking something from an extra db table to display on a certain page, eg page_id=4
$pageVar = $wpdb->get_var(SELECT var FROM my_table WHERE something=’something_else’);
and then you also want to SEO the <title> a little, so in header.php you put:-
<?php if (is_page(’4′)) $extraTitle = ‘ยป ‘ . $pageVar; ?>
<title><?php bloginfo(’name’); ?> <?php wp_title(); ?> <?php echo $extraTitle; ?></title>
It won’t work - $pageVar doesn’t have global scope, because of the method used to get the header on the page.
<?php get_header(); ?>
Instead, one way round this is to use:
<?php include(TEMPLATEPATH . ‘/header.php’); ?>
and it will work…
This has the nature of a hack - use sparingly and probably not in themes for general release. And stay away from $_GLOBALS
