我在函数中添加了自定义分类法。php。代码如下：

function create_autor_nonhierarchical_taxonomy() {

    $labels = array(
        \'name\' => _x( \'Autor\', \'taxonomy general name\' ),
        \'singular_name\' => _x( \'Autor\', \'taxonomy singular name\' ),
        \'search_items\' =>  __( \'Buscar autores\' ),
        \'popular_items\' => __( \'Autores populares\' ),
        \'all_items\' => __( \'Todos los autores\' ),
        \'parent_item\' => null,
        \'parent_item_colon\' => null,
        \'edit_item\' => __( \'Editar autor\' ), 
        \'update_item\' => __( \'Actualizar autor\' ),
        \'add_new_item\' => __( \'Añadir nuevo autor\' ),
        \'new_item_name\' => __( \'Nombre del nuevo autor\' ),
        \'separate_items_with_commas\' => __( \'Separa los autores con comas\' ),
        \'add_or_remove_items\' => __( \'Añadir o eliminar autores\' ),
        \'choose_from_most_used\' => __( \'Elije ente los autores más utilizados\' ),
        \'menu_name\' => __( \'Autor\' ),
    ); 

    register_taxonomy( \'autor\', \'product\', array(
        \'hierarchical\' => false,
        \'labels\' => $labels,
        \'show_ui\' => true,
        \'show_admin_column\' => true,
        \'update_count_callback\' => \'_update_post_term_count\',
        \'query_var\' => true,
        \'rewrite\' => array( \'slug\' => \'autor\' ),
    ));
}

add_action( \'init\', \'create_autor_nonhierarchical_taxonomy\', 0 );

function show_product_autor(){

    $authors = wp_get_post_terms( get_the_ID(), \'autor\' );
    $author = array_pop($authors);

    $authorTeamPg = get_page_by_title( $author->name, \'OBJECT\', \'team\' );
    $authorTeamPgLink = get_permalink( $authorTeamPg->ID);

    echo "<b>AUTOR: </b><a href=\'{$authorTeamPgLink}\'>{$author->name}</a>",\'<br />\';

}

add_action( \'woocommerce_single_product_summary\', \'show_product_autor\', 24 );

现在，我有超过一位作者的书。如何更改代码以显示实例2或3个作者？此外，有些书有一个编辑，而不是一个作者（一本书有许多作者，只有一个负责出版）。通常在这种情况下，编辑器的名称后面跟着一个括号，如（ed.）。如何将此选项添加到“作者”字段？

function show_product_autor(){    
    $authors = wp_get_post_terms( get_the_ID(), \'autor\' );

    foreach($authors as $author) {
        $authorTeamPg = get_page_by_title( $author->name, \'OBJECT\', \'team\' );
        $authorTeamPgLink = get_permalink( $authorTeamPg->ID);
        echo "<b>AUTOR: </b><a href=\'{$authorTeamPgLink}\'>{$author->name}</a>",\'<br />\';
    }
}

function show_product_autor(){    
    $authors = wp_get_post_terms( get_the_ID(), \'autor\');
    $output  = array();
    foreach($authors as $author) {
        if(!$author->parent) { //if there is no parent term
            $authorTeamPg = get_page_by_title( $author->name, \'OBJECT\', \'team\' );
            $authorTeamPgLink = get_permalink( $authorTeamPg->ID);
            $output[$author->term_id][\'url\'] = "<a href=\'{$authorTeamPgLink}\'>{$author->name}</a>";
        } else {
            $output[$author->parent][\'ed\'] = \' (ed.)\';
        }
    }
    $outputfinal = array();
    foreach($output as $line) {
        if(!empty($line[\'url\'])) { //just to be safe, check the url is there
            $outputfinal[] = (empty($line[\'ed\'])) ? $line[\'url\'] : $line[\'url\'].$line[\'ed\'];
        }
    }
    echo \'<b>AUTOR: </b>\'.implode(\', \', $outputfinal).\'<br />\';
}
