[wp-hackers] Why in the heck won't this work?

[DD32]

Perhaps this will help?

term_taxonomy_id is the Category ID


<?php
$post_ID = 28;

$categories = wp_get_object_terms($post_ID, 'category');

var_dump($categories);
?>

array
    0 =>
      object(stdClass)[165]
        public 'term_id' => string '9' (length=1)
        public 'name' => string 'Test Cat' (length=14)
        public 'slug' => string 'test-cat' (length=14)
        public 'term_group' => string '0' (length=1)
        public 'term_taxonomy_id' => string '9' (length=1)
        public 'taxonomy' => string 'category' (length=8)
        public 'description' => string '' (length=0)
        public 'parent' => string '0' (length=1)
        public 'count' => string '1' (length=1)
    1 =>
      object(stdClass)[166]
        public 'term_id' => string '14' (length=2)
        public 'name' => string 'Wordpress Plugins' (length=17)
        public 'slug' => string 'wordpress-plugins' (length=17)
        public 'term_group' => string '0' (length=1)
        public 'term_taxonomy_id' => string '14' (length=2)
        public 'taxonomy' => string 'category' (length=8)
        public 'description' => string '' (length=0)
        public 'parent' => string '0' (length=1)
        public 'count' => string '1' (length=1)
