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
        )

)

And that’s how you get all terms for a post in wordpress. I decided to write this after unsuccessfully searching for the terms below. Leave a comment if this helped you or if you have a fix / improvement / question.
