面包屑未显示自定义类别帖子类型

时间：2014-08-29 作者：Nsokyi

当我在页面上的面包屑菜单中显示自定义帖子类型类别时，我遇到了一个问题，它看起来如下所示

主页//帖子标题

应该是什么时候

主页/自定义猫名/帖子标题

它显示页面上的帖子和帖子标题，但不显示类别？

面包屑菜单代码：

            /*********************
            breadcrumbs menu
            *********************/
            function the_breadcrumb(){
                echo \'<ul class="crumbs">\';
                if (!is_home()){
                    echo \'<li><a href="\';
                    echo get_option(\'home\');
                    echo \'">\';
                    echo \'Home\';
                    echo \'</a></li><li class="separator"> &#124; </li>\';
                    if (is_category() || is_single(\'post\')){
                        echo \'<li>\';
                        the_category(\' </li><li class="separator"> &#124; </li><li> \');
                        if (is_single()){
                            echo \'</li><li class="separator"> &#124; </li><li>\';
                            the_title();
                            echo \'</li>\';
                        }
                    } elseif (is_page()){
                        echo \'<li>\';
                        echo the_title();
                        echo \'</li>\';
                    }
                }
                elseif (is_tag()){
                    single_tag_title();
                }
                elseif (is_day()){
                    echo"<li>Archive for "; the_time(\'F jS, Y\'); echo\'</li>\';
                }
                elseif (is_month()){
                    echo"<li>Archive for "; the_time(\'F, Y\'); echo\'</li>\';
                }
                elseif (is_year()){
                    echo"<li>Archive for "; the_time(\'Y\'); echo\'</li>\';
                }
                elseif (is_author()){
                    echo"<li>Author Archive"; echo\'</li>\';
                }
                elseif (isset($_GET[\'paged\']) && !empty($_GET[\'paged\'])){
                    echo "<li>Blog Archives"; echo\'</li>\';
                }
                elseif (is_search()){
                    echo"<li>Search Results"; echo\'</li>\';
                }
                echo \'</ul>\';
            }

我仍然不能百分之百确定需要在何处以及显示什么。

如果需要显示当前单个帖子的类别，则需要使用get_the_category 代替the_category 像the_category 需要在循环内调用。您可以使用get_the_category 如下（记住使用global $post 检索帖子ID）

<?php
global $post;
$categories = get_the_category($post->ID);
var_dump($categories);
?>

如果需要在类别页面上获取类别名称，可以使用get_query_var(\'cat\') 检索有关当前类别页的信息。
下面是我在网站上使用的面包屑示例。
if ( ! function_exists( \'pietergoosen_breadcrumbs\' ) ) : function pietergoosen_breadcrumbs() { /* === OPTIONS === */ $text[\'home\'] = _x( \'Home\', \'Home\', \'pietergoosen\' ); // text for the \'Home\' link $text[\'category\'] = __( \'Archive by Category "%s"\', \'pietergoosen\' ); // text for a category page $text[\'search\'] = __( \'Search Results for "%s" Query\', \'pietergoosen\' ); // text for a search results page $text[\'tag\'] = __( \'Posts Tagged "%s"\', \'pietergoosen\' ); // text for a tag page $text[\'author\'] = __( \'Posts Posted by %s\', \'pietergoosen\' ); // text for an author page $text[\'404\'] = __( \'Error 404\', \'pietergoosen\' ); // text for the 404 page $show_current = 1; // 1 - show current post/page/category title in breadcrumbs, 0 - don\'t show $show_on_home = 0; // 1 - show breadcrumbs on the homepage, 0 - don\'t show $show_home_link = 1; // 1 - show the \'Home\' link, 0 - don\'t show $show_title = 1; // 1 - show the title for the links, 0 - don\'t show $delimiter = \' » \'; // delimiter between crumbs $before = \'<span class="current">\'; // tag before the current crumb $after = \'</span>\'; // tag after the current crumb /* === END OF OPTIONS === */ global $post; $here_text = __(\'You are currently here!
