假设分类名称为“动物”

<?php
    //This will show all the terms in taxonomy whether they have posts or not thus the "hide_empty"
    $terms = get_terms( array ( \'taxonomy\' => \'animals\', \'hide_empty\' => false, \'parent\' => 0, \'orderby\' => \'description\', \'order\' => \'ASC\' ));

    foreach ($terms as $term) {
        // The $term is an object, so we can get the names.
        //use var_dump($term) to see other options available
        echo $name = $term->name;
    }
?>

这个wp_get_post_terms() function 使用调用时返回一个或多个术语名称array( \'fields\' => \'names\' ). 所以你有几个不同的选择。

抓取找到的第一个术语名称。

<?php
$term_names = wp_get_post_terms($post->ID, \'my_taxonomy\', array(\'fields\' => \'names\'));

if ( ! empty( $term_names ) ) {
  echo $term_names[0]; // Cats
}

<?php
$term_names = wp_get_post_terms($post->ID, \'my_taxonomy\', array(\'fields\' => \'names\'));

echo implode(\', \', $term_names); // Cats, Pets, Animals

<?php
$term_names = wp_get_post_terms($post->ID, \'my_taxonomy\', array(\'fields\' => \'names\'));

foreach( $term_names as $name ) {
    echo $name.\'<br />\';
}

它与此代码一起工作，只显示名称，但是输出以小字符显示，因此我只需要以某种方式将其大写

<?php // Get terms for post $terms = get_the_terms( $post->ID , \'my_taxonomy\' ); // Loop over each item since it\'s an array if ( $terms != null ){ foreach( $terms as $term ) { // Print the name method from $term which is an OBJECT print $term->slug ; // Get rid of the other data stored in the object, since it\'s not needed unset($term); } } ?>
