Trying to translate Kafkaesqui

  • All I want is the parent category id for use with children. Here’s what Kafkaesqui wrote a few months back

    <?php
$cat_object = $wp_query->get_queried_object();
$cat_parent = $cat_object->category_parent;
?>

    but then what do I do with that? I tried to echo &cat_parent but that did nothing – doesn’t seem to matter whether I’m in or out of the loop

    this didn’t work either

    $cat = get_the_category();
if ($cat->cat_parent = 0) {
$cat_parent = $cat->cat_ID;
} else {
$cat_parent = $cat->cat_parent;
}
echo $cat_parent;

  • use this:

    <?php
$cat_object = $wp_query->get_queried_object();
$parentcat = ($cat_object->category_parent) ? $cat_object->category_parent : $cat;
wp_list_cats("child_of=$parentcat");
?>

    it works perfect — on archive.php.

    any chance to get this working on single.php? i played around with this but had no luck.

    Try this: List children of current category.

    None of this will work on a single post page.

    For that you’d have to collect it* through get_the_category(). Outside The Loop would involve this:

    <?php
global $post;
$categories = get_the_category();
$category = $categories[0];
$parent = ($category->category_parent) ? $category->category_parent : $category->cat_ID;
wp_list_cats("child_of=$parent");
?>

    To alternate between single and category (archive) queries, something like this should do it:

    <?php
if( is_single() ) {
	global $post;
	$categories = get_the_category();
	$category = $categories[0];
} else {
	$category = $wp_query->get_queried_object();
}
$parent = ($category->category_parent) ? $category->category_parent : $category->cat_ID;

if( $parent )
	wp_list_cats("child_of=$parent");
?>

    * This is really meant for blogs with posts residing in just one category.
