get_terms（'类别'）

Question

I am trying to display the categories with the get_terms function with the following code:

$categories = get_terms( 'category');
$categories_count = count($categories);

                    for ($i = 0; $i < $categories_count; $i++) {
                        echo($i . $categories[$i]->name.' <br /> ');
                    }

But for some reason doesnt display all the categories, a couple of them are missing uncategorized and something else, this is what I see on the screen when i run this code:

• 0 Chairs
• 1
• 2 Interiors
• 3
• 4 Featured

Thanks very much,

Answer 1

Your code is correct as far as I can tell, however the will be an issue in get_terms() OR the terms themselves don't actually have a name.

Answer 2

You can try get_categories() instead of get_terms() . This is how you should do it:

<?php 
    $categories = get_categories(); 
    $number = 1;
    foreach ($categories as $category) {
        print $number . $category->cat_name . '<br />';
        $number++;
    }
?>

Just give it a shot...

To display tags and/or categories list:

<span>Tags: <?php 
                    global $post;
                    $terms = wp_get_post_terms($post->ID, 'your-taxonomy');
                    if ($terms) {
                        $output = array();
                            foreach ($terms as $term) {
                            $output[] = '<a href="' .get_term_link( $term->slug, 'your-taxonomy') .'\*for CPT please add url suffix /?post_types=your_cpt*\">' .$term->name .'</a>';
                            }
                            echo join( ', ', $output );
                                }
                                        ?>

                <span>
