所以我的问题是，我可以把代码放在哪里来显示分类法？我找到了这个代码

`function get_taxonomies( $args = array(), $output = \'names\', $operator = \'and\' ) {
    global $wp_taxonomies;
 
    $field = ( \'names\' === $output ) ? \'name\' : false;
 
    return wp_filter_object_list( $wp_taxonomies, $args, $operator, $field );
}`

但它不起作用，我会出错。我的意思是我必须做一个新的文件把它放在那里？

分类法是

   function create_post_type()
{
    $labels = array(
        \'name\' => __(\'Offer\'),
        \'singular_name\' => __(\'offer\'),
        \'add_new\' => __(\'New offer\'),
        \'add_new_item\' => __(\'Add New offer\'),
        \'edit_item\' => __(\'Edit offer\'),
        \'new_item\' => __(\'New offer\'),
        \'view_item\' => __(\'View offer\'),
        \'search_items\' => __(\'Search offer\'),
        \'not_found\' =>  __(\'No offer Found\'),
        \'not_found_in_trash\' => __(\'No offer found in Trash\'),
    );
    $args = array(
        \'labels\' => $labels,
        \'has_archive\' => true,
        \'public\' => true,
        \'supports\' => array(
            \'title\',
            \'editor\',
            \'excerpt\',
            \'custom-fields\',
            \'thumbnail\',
            \'page-atributes\'
        ),
        \'taxonomies\' => array(\'post_tag\', \'category\'),
    );
    register_post_type(\'offer\', $args);
}

add_action(\'init\', \'create_post_type\');


function htl_register_taxonomy()
{
    $args = array(
        \'labels\' => array(
            \'name\' => __(\'hotel\'),
            \'singular_name\' => __(\'hotel\'),

        ),
        \'public\' => true,
    );

    register_taxonomy(\'hotel\', array(\'offer\'), $args);
}
add_action(\'init\', \'htl_register_taxonomy\');

<?php

$args = array(
    \'post_type\' => \'offer\',
    \'posts_per_page\' => -1 //show all posts
);

$loop = new WP_Query($args);


if($loop->have_posts()){
    while($loop->have_posts()){
        $loop->the_post();

    $id = get_the_ID();

    $tax = get_the_terms($id, \'hotel\');

    print_r($tax);

    }//endwhile
    wp_reset_postdata();
}//endif
