Your hunch paid off. That’s awesome. Thank you so much!

Thx t31os_ – it didn’t fix the problem, but I see how it’s easier to read.

I had a problem once with display issues when I called a variable in the middle of an echo statement and the only way to resolve it was to bust everything into its own isolated echo. I don’t know why, but it did work, and since that day I’ve been overly cautious.

That does work much better, but because my site’s a bit of a pain in the butt, I’m going to throw another wrench into the works…

There are 2 category IDs I want to exclude, BUT they are the main parent categories, fiction & non-fiction, for all other books. If I put in a category__not_in statement after the category__in statement I loose everything.

Is there a simple way to take the array once it’s passed to the function and say drop these 2 values but keep all the others?

alchymyth – that doesn’t seem to be working. It seems to be passing every category, not just the post specific ones.

Here’s my call from within the post:

<?php 

$bookID = $post->ID;
$inCats =  wp_get_post_categories($post->ID);
// alchymyth's suggestion

listRelated($inCats, $bookID);

?>

And here’s my function:

function listRelated($inCats, $bookID) {

	$args = array(
		 	'category__in' => $inCats,
			'post__not_in' => $bookID,
			'orderby' => 'modified',
			'order' => 'DESC',
			'post_type' => 'post',
			'post_status' => 'publish',
			'posts_per_page' => 5,
			'caller_get_posts'=> 1
		 );	

			$my_query1 = new WP_Query($args);
				while ($my_query1->have_posts()) : $my_query1->the_post();
				$do_not_duplicate1 = $post->ID; ...

Any other ideas how to auto-pass the categories?

Well, if you write a book of your coolest WP tricks I’ll be first in line to buy it.

Any chance I could coax you into posting your revised code, because I seem to get an error with everything I try.

By the way, I do really appreciate all the help. Something’s just not clicking here.

I know we’re getting closer to a solution, but I’m getting one of those pesky fatal errors:

Fatal error: Call to a member function get_col() on a non-object in /***/wp-content/plugins/exec-php/includes/runtime.php(42) : eval()'d code on line 7

Do I need to globalize something somewhere first perhaps?

Yes, we want posts listed in order by a custom field, but grouped & separated alphabetically.

We want to have A-Z navigation across the top:

A – B – C – D – etc.

Clicking on A would give you any author with a last name beginning with A, and so on down the line.

It’d be a really handy way for users to browse a bunch of books.
