Doesn’t $catID = 3; work, without any quotes?
.. See previous post 😉 That.
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(); ?>
.....
Try
$recent = new WP_Query( array( 'cat' => $catID ) );
while($recent->have_posts()) : $recent->the_post();
If that doesn’t work verify that you actually have posts with that category, etc.
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
---------
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?
The answer is
$recent = new WP_Query( array( 'category__in' => $catID ) );
Thank you EVERYONE for helping me out!!!
