The answer is
$recent = new WP_Query( array( 'category__in' => $catID ) );

Thank you EVERYONE for helping me out!!!

I think that might actually be working correctly and it’s picking up parent/child stuff.

categories 3&4 are children of 23
category 3 is a child of 4

How do I tell it to ignore parents & children?

I’m not getting that one to work either. I know I’m doing something REALLY dumb!! And now I see there are problems other than the quote problem.

single.php

<?php $i = 1;
$catIDs = array("23","3","4");
foreach ($catIDs as $catID) {
echo "loop #" . $i . "<br />";
listGames($catID);
echo "<br />---------<br />";
$i++;
} ?>

function.php

function listGames($catID) {
$recent = new WP_Query();
$recent->query( "cat=$catID" );
while($recent->have_posts()) : $recent->the_post();
the_title();
echo "<br />";
endwhile; }

OR function.php (from Ron)

function listGames($catID) {
$recent = new WP_Query( array( 'cat' => $catID ) );
while($recent->have_posts()) : $recent->the_post();
the_title();
echo "<br />";
endwhile; }

output

loop #1
POST FROM CAT 4
POST FROM CAT 3
POST FROM CAT 23

---------
loop #2
POST FROM CAT 3

---------
loop #3
POST FROM CAT 4
POST FROM CAT 3

---------

The double/single quote problem still happens even without the quotes on the $catID =

And, the code actually sets the variable elsewhere. Was hoping the cut down code might help, but it just added more confusion. Here’s the real code

function listGames($catID) {
echo "catID is " . $catID . "<br/>"; // works
$recent = new WP_Query();
$recent->query("cat=$catID");
while($recent->have_posts()) : $recent->the_post(); ?>

Thank you.

I apologize – I just realized that this portion of the profile was coming from a plugin, not the WP core.
