I'm working from the twenty ten theme and have this code to return the date if the post belongs to a category and return nothing if it doesn't (in this case, if it's a custom post type, it won't return the date).
<?php if ( in_category('') ) : ?>
<div class="entry-meta">
<?php twentyten_posted_on(); ?>
</div><!-- .entry-meta -->
<?php else: ?>
<?php endif ?>
It works fine if I enter the name of a given category, but I don't want to have to manage this code every time I add a new category. Is there something I can add that globally accepts all categories? Haven't been able to find that answer anywhere.
So are you saying you want to display that date if the post has ANY category assigned?
I didn't test but try:
<?php
// in post loop, if post has terms belonging to the taxonomy 'category', display a message
$terms = wp_get_post_terms( $post->ID , 'category', '');
if ( !is_wp_error($terms) && $terms ) {
echo 'found featured terms on this post';
}
?>
EDIT: Too slow! Should have refreshed the screen!
Here is a query that should work:
<?php $sql = "SELECT tr.object_id FROM $wpdb->term_relationships tr
JOIN $wpdb->term_taxonomy tt
ON (tt.term_taxonomy_id = tr.term_taxonomy_id AND tt.taxonomy = 'category')
WHERE tr.object_id = $post->ID";
$my_query = $wpdb->get_results($sql);
if ( $my_query ) : ?>
<div class="entry-meta">
<?php twentyten_posted_on(); ?>
</div><!-- .entry-meta -->
<?php else: ?>
<?php endif ?>
Perfection. I gave the second suggestion a go and it worked right away.
Thanks to both of you!
