Get a category name/slug/id for a post or archive page
There's obviously a little context missing for this paste, but the basic idea should be clear ;-)
<?php
if ( is_single() ) {
$cats = get_the_category();
$cat = $cats[0]; // let's just assume the post has one category
}
else { // category archives
$cat = get_category( get_query_var( 'cat' ) );
}
$cat_id = $cat->cat_ID;
$cat_name = $cat->name;
$cat_slug = $cat->slug;
?>
Thanks for this. I was having a heck of a time trying to get the category ID from within a category archive page.
