WordPress: Get all terms for a post

First you need to get the available taxonomies so that you can pass them to the `wp_get_object_terms` function to get all of the terms / categories / tags / custom tax terms associated with a single post:

$taxonomies = get_taxonomies(”,’names’);
print_r($taxonomies); //optional for debugging

That will likely return something like this:

Array
(
[category] => category
[post_tag] => post_tag
[nav_menu] => nav_menu
[link_category] => link_category
[post_format] => post_format
[product_type] => product_type
[product_cat] => product_cat
[product_tag] => product_tag
[product_shipping_class] => product_shipping_class
[shop_order_status] => shop_order_status
)

Next you can use the `wp_get_object_terms` function, passing the post’s ID(s) and the list of taxonomies to get all of the terms associated:

global $post; //optional if you are inside the “loop”
$terms = wp_get_object_terms($post->ID,$taxonomies);
print_r($terms); //optional for debugging

Array
(
[0] => stdClass Object
(
[term_id] => 2
[name] => Blogroll
[slug] => blogroll
[term_group] => 0
[term_taxonomy_id] => 2
[taxonomy] => link_category
[description] =>
[parent] => 0
[count] => 7
)

[1] => stdClass Object
(
[term_id] => 14
[name] => Lightweight
[slug] => lightweight
[term_group] => 0
[term_taxonomy_id] => 14
[taxonomy] => product_cat
[description] =>
[parent] => 0
[count] => 1
)

[2] => stdClass Object
(
[term_id] => 15
[name] => tag1
[slug] => tag1
[term_group] => 0
[term_taxonomy_id] => 15
[taxonomy] => product_tag
[description] =>
[parent] => 0
[count] => 1
)

[3] => stdClass Object
(
[term_id] => 5
[name] => simple
[slug] => simple
[term_group] => 0
[term_taxonomy_id] => 5
[taxonomy] => product_type
[description] =>
[parent] => 0
[count] => 1
)

)
