下面由WordPress教程栏目给大家分享一个WordPress面包屑导航代码，希望对需要的朋友有所帮助！
转载分享一段WordPress面包屑导航代码，支持自定义帖子类型、自定义分类，但貌似在分类归档页面不能显示父子分类层级有点遗憾。
将代码添加到当前主题函数模板functions.php中：
/**
* WordPress Breadcrumbs
*/
function tsh_wp_custom_breadcrumbs() {
$separator = '/';
$breadcrumbs_id = 'tsh_breadcrumbs';
$breadcrumbs_class = 'tsh_breadcrumbs';
$home_title = esc_html__('Home', 'your-domain');
// Add here you custom post taxonomies
$tsh_custom_taxonomy = 'product_cat';
global $post,$wp_query;
// Hide from front page
if ( !is_front_page() ) {
echo '';
// Home
echo '- ' . $home_title . '
';
echo '- ' . $separator . '
';
if ( is_archive() && !is_tax() && !is_category() && !is_tag() ) {
echo '- ' . post_type_archive_title('', false) . '
';
} else if ( is_archive() && is_tax() && !is_category() && !is_tag() ) {
// For Custom post type
$post_type = get_post_type();
// Custom post type name and link
if($post_type != 'post') {
$post_type_object = get_post_type_object($post_type);
$post_type_archive = get_post_type_archive_link($post_type);
echo '- ' . $post_type_object->labels->name . '
';
echo '- ' . $separator . '
';
}
$custom_tax_name = get_queried_object()->name;
echo '- ' . $custom_tax_name . '
';
} else if ( is_single() ) {
$post_type = get_post_type();
if($post_type != 'post') {
$post_type_object = get_post_type_object($post_type);
$post_type_archive = get_post_type_archive_link($post_type);
echo '- ' . $post_type_object->labels->name . '
';
echo '- ' . $separator . '
';
}
// Get post category
$category = get_the_category();
if(!empty($category)) {
// Last category post is in
$last_category = $category[count($category) - 1];
// Parent any categories and create array
$get_cat_parents = rtrim(get_category_parents($last_category->term_id, true, ','),',');
$cat_parents = explode(',',$get_cat_parents);
// Loop through parent categories and store in variable $cat_display
$cat_display = '';
foreach($cat_parents as $parents) {
$cat_display .= '- '.$parents.'
';
$cat_display .= '- ' . $separator . '
';
}
}
$taxonomy_exists = taxonomy_exists($tsh_custom_taxonomy);
if(empty($last_category) && !empty($tsh_custom_taxonomy) && $taxonomy_exists) {
$taxonomy_terms = get_the_terms( $post->ID, $tsh_custom_taxonomy );
$cat_id = $taxonomy_terms[0]->term_id;
$cat_nicename = $taxonomy_terms[0]->slug;
$cat_link = get_term_link($taxonomy_terms[0]->term_id, $tsh_custom_taxonomy);
$cat_name = $taxonomy_terms[0]->name;
}
// If the post is in a category
if(!empty($last_category)) {
echo $cat_display;
echo '- ' . get_the_title() . '
';
// Post is in a custom taxonomy
} else if(!empty($cat_id)) {
echo '- ' . $cat_name . '
';
echo '- ' . $separator . '
';
echo '- ' . get_the_title() . '
';
} else {
echo '- ' . get_the_title() . '
';
}
} else if ( is_category() ) {
// Category page
echo '- ' . single_cat_title('', false) . '
';
} else if ( is_page() ) {
// Standard page
if( $post->post_parent ){
// Get parents
$anc = get_post_ancestors( $post->ID );
// Get parents order
$anc = array_reverse($anc);
// Parent pages
if ( !isset( $parents ) ) $parents = null;
foreach ( $anc as $ancestor ) {
$parents .= '- ' . get_the_title($ancestor) . '
';
$parents .= '- ' . $separator . '
';
}
// Render parent pages
echo $parents;
// Active page
echo '- ' . get_the_title() . '
';
} else {
// Just display active page if not parents pages
echo '- ' . get_the_title() . '
';
}
} else if ( is_tag() ) { // Tag page
// Tag information
$term_id = get_query_var('tag_id');
$taxonomy = 'post_tag';
$args = 'include=' . $term_id;
$terms = get_terms( $taxonomy, $args );
$get_term_id = $terms[0]->term_id;
$get_term_slug = $terms[0]->slug;
$get_term_name = $terms[0]->name;
// Return tag name
echo '- ' . $get_term_name . '
';
} elseif ( is_day() ) { // Day archive page
// Year link
echo '- ' . get_the_time('Y') . ' Archives
';
echo '- ' . $separator . '
';
// Month link
echo '- ' . get_the_time('M') . ' Archives
';
echo '- ' . $separator . '
';
// Day display
echo '- ' . get_the_time('jS') . ' ' . get_the_time('M') . ' Archives
';
} else if ( is_month() ) { // Month Archive
// Year link
echo '- ' . get_the_time('Y') . ' Archives
';
echo '- ' . $separator . '
';
// Month display
echo '- ' . get_the_time('M') . ' Archives
';
} else if ( is_year() ) { // Display year archive
echo '- ' . get_the_time('Y') . ' Archives
';
} else if ( is_author() ) { // Author archive
// Get the author information
global $author;
$userdata = get_userdata( $author );
// Display author name
echo '- ' . 'Author: ' . $userdata->display_name . '
';
} else if ( get_query_var('paged') ) {
// Paginated archives
echo '- '.__('Page') . ' ' . get_query_var('paged') . '
';
} else if ( is_search() ) {
// Search results page
echo '- Search results for: ' . get_search_query() . '
';
} elseif ( is_404() ) {
// 404 page
echo '- ' . 'Error 404' . '
';
}
echo '
';
}
}
将调用代码放到主题模板适当位置比如header.php中：
配套样式：
#tsh_breadcrumbs .separator{
font-size:20px;
color:#ccc;
font-weight:100;
}
#tsh_breadcrumbs{
overflow:hidden;
text-align: center;
list-style:none;
margin:11px 0;
}
#tsh_breadcrumbs li{
margin-right:14px;
display:inline-block;
vertical-align:middle;
