well, you have a couple of choices in that regard.
you can either use wp_list_bookmarks(); in that location instead of wp_list_pages… and then make your menu yourself, via the manage/links option in the wp Admin panel….
or…
you can create a new page template, (call it redirect.php or something) that looks like this:
<?php
/*
Template Name: Redirect
*/
if (have_posts()) {
the_post();
$pattern = '@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@';
preg_match($pattern, get_the_excerpt(), $matches);
if ($matches[0]) header('Location: '.$matches[0]);
else echo 'Enter a URL into your page body text.';
}
?>
Then set that as the page template for any page you wish to use as a redirector.
The contents of that page should just be a link to where you want to go.
It is a little twisted, but I really like twisted ??
NOTE: Make sure there’s no white-space before the <?php
