Display posts with tag for custom post type only

Question

I have this is my functions.php file to create tags only for custom post type called 'image-gallery':

register_taxonomy(
  'image-gallery_tags',
  'image-gallery',
  array(
    'label'        => __( 'Image Tags' ),
    'rewrite'      => false,
    'hierarchical' => false,
    'capabilities' => array( 'edit_terms' => 'manage_categories' )
  )
);

But I can't get the list of tags to show in the post loop on the front end. I have tried get_the_tags(); and get_the_tag_list(); but they will only show tags which are generic to all posts, not the tags for the custom post type. Any help?

Answer 1

get_the_tags() is a shortcut function to get the terms from the post_tags taxonomy.

What you have done is make a new and different taxonomy. And you will need to use get_the_terms() to get your required data.

E.g.

$terms = get_the_terms($post, 'image-gallery_tags');
