How can WP remain consistent with my dynamic includes?

Oh.

Mainly, my other pages are in my default themes folder, so that’s where I have the dynamic includes code – in the index of my default theme.

Either use full (not relative) paths or put all of your php include files into your theme folder and use this format to include them:

<?php include (TEMPLATEPATH . '/my-include.php'); ?>

Where should I put that format? Into my themes index page?

Insert this code into one or more of your theme’s template pages (index.php, single.php, page.php, etc.). Where you put it depends on where you want it to appear.

How would I use full paths? Should I just directly upload the content inside my WordPress directory into the my site’s root directory?

here’s the code I have in my default themes index:

<?php get_header(); ?>
<?php if (isset($_GET[‘x’])) {
if (strpos($_GET[‘x’], “/”)) {
$dir = substr(str_replace(‘..’, ”, $_GET[‘x’]), 0, strpos($_GET[‘x’], “/”)) . “/”;
$file = substr(strrchr($_GET[‘x’], “/”), 1);
if (file_exists($dir.$file.”.php”)) {
include($dir.$file.”.php”);
} else {
include(“pages/default.php”);
}
} else {
if (file_exists(basename($_GET[‘x’]).”.php”)) {
include(basename($_GET[‘x’]).”.php”);
} else {
include(“pages/default.php”);
}
}
} else {
include(“pages/default.php”);
} ?>

<?php get_footer(); ?>

pages/default.php is a relative path. Either put the includes into your theme folder and use the TEMPLATEPATH code or use a full path (one that starts with http).

Honestly, I appreciate your effort! The full path method does not work.
I don’t understand what you mean by putting the “includes into [my] theme folder”… define “includes”? Do you mean my header.php/footer.php?
I’m more or less new to PHP and the exact terminology.
I apologize!
