Answer 1

Get the post category if you have a custom post_type

<?php
$categories = get_the_terms( $post->ID, 'taxonomy' );
// now you can view your category in array:
// using var_dump( $categories );
// or you can take all with foreach:
foreach( $categories as $category ) {
    echo $category->term_id . ', ' . $category->slug . ', ' . $category->name . '<br />';
} ?>

Answer 2

Get the category objects:

$cats = get_the_category($id);

---

Just echo the name:

echo $cats[0]->name;

---

If you want to output a link, use this:

<a href="<?php echo get_category_link($cats[0]->cat_ID); ?>">
    <?php echo $cats[0]->name; ?>
</a>

Note: instead of wp_get_post_categories($id), you could just use get_the_category().

---

Update: if you want to display all the categories, just loop through them:

<?php foreach ( $cats as $cat ): ?>

    <a href="<?php echo get_category_link($cat->cat_ID); ?>">
        <?php echo $cat->name; ?>
    </a>

<?php endforeach; ?>

Answer 3

If anybody else needs help with this you can use this inside posts loop:

<p><?php _e( 'Category: ', 'themename' ); the_category(', '); // Separated by commas ?></p>

Answer 4

Thanks Joseph. I have extended your code so that the word 'Category' changes to 'Categories' when there are more than one category. There may be a better way of doing this but I couldn't find it anywhere :)

<p>
    <?php 
    $id = get_the_ID();
    $cats = get_the_category($id);
    echo ( count($cats) == 1  ? 'Category: ' : 'Categories: ');
    $c = 0; $n = 0;
    $c = count($cats);
    foreach ( $cats as $cat ):
        $n++; ?>
        <a href="<?php echo get_category_link($cat->cat_ID); ?>">
            <?php echo $cat->name; echo ( $n > 0 && $n < $c ? ', ' : ''); ?>
        </a>
    <?php endforeach; ?>
