面包屑wordpress中的完整路径

Question

我想在wordpress模板中用面包屑的完整路径

现在只显示主页和类别

我想要主页 - 类别 - 带有指向此页面链接的文章标题，以及有效的架构标记

现在代码看起来像这样 版本 Wordpress 4.8.1

function barcelona_breadcrumb() {
    if ( barcelona_get_option( 'show_breadcrumb' ) != 'on' ) {
        return;
    }
    $barcelona_post_type = is_single() ? get_post_type() : NULL;
    $barcelona_sep_icon = '';
    $barcelona_items = '';
    if ( ( is_single() && $barcelona_post_type == 'post' && ! is_attachment() ) || is_category() ) {
        $barcelona_categories = is_category() ? array() : get_the_category();
        $barcelona_current_cat = $barcelona_last_cat = is_category() ? get_queried_object() : $barcelona_categories[0];
        $barcelona_counter = 3;
        while ( $barcelona_current_cat->category_parent != '0' ) {
            $barcelona_current_cat = get_category( $barcelona_current_cat->category_parent );

试试下面的代码，把下面的代码放在functions.php中

function the_breadcrumbs() {

    global $post;

    if (!is_home()) {

        echo "<a href='";
        echo get_option('home');
        echo "'>";
        echo "Site's name here";
        echo "</a>";

        if (is_category() || is_single()) {

            echo " > ";
            $cats = get_the_category( $post->ID );

            foreach ( $cats as $cat ){
                echo $cat->cat_name;
                echo " > ";
            }
            if (is_single()) {
                the_title();
            }
        } elseif (is_page()) {

            if($post->post_parent){
                $anc = get_post_ancestors( $post->ID );
                $anc_link = get_page_link( $post->post_parent );

                foreach ( $anc as $ancestor ) {
                    $output = " > <a href=".$anc_link.">".get_the_title($ancestor)."</a> > ";
                }

                echo $output;
                the_title();

            } else {
                echo ' > ';
                echo the_title();
            }
        }
    }
elseif (is_tag()) {single_tag_title();}
elseif (is_day()) {echo"Archive: "; the_time('F jS, Y'); echo'</li>';}
elseif (is_month()) {echo"Archive: "; the_time('F, Y'); echo'</li>';}
elseif (is_year()) {echo"Archive: "; the_time('Y'); echo'</li>';}
elseif (is_author()) {echo"Author's archive: "; echo'</li>';}
elseif (isset($_GET['paged']) && !empty($_GET['paged'])) {echo "Blogarchive: "; echo'';}
elseif (is_search()) {echo"Search results: "; }
}

将下面的代码放在 header.php 中

 if(function_exists('the_breadcrumbs')) the_breadcrumbs();
