实际上，您需要将breadcrumbs函数挂接到在购物车和检查页面中激发的任何挂钩上。在下面的例子中，我调用了the_dramatist_show_breadcrumbs 我已经迷上了woocommerce_before_cart 对于购物车页面和woocommerce_before_checkout_form 用于签出表单。整个代码块如下所示-
For minimal usage ( Only at pages, As you wanted in comment )-
根据您的评论进行更新。这个东西也经过了测试。
add_action( \'woocommerce_before_cart\', \'the_dramatist_page_breadcrumbs\');
add_action( \'woocommerce_before_checkout_form\', \'the_dramatist_page_breadcrumbs\');
// Breadcrumbs
function the_dramatist_page_breadcrumbs() {
// Settings
$separator = \'>\';
$breadcrums_id = \'breadcrumbs\';
$breadcrums_class = \'breadcrumbs\';
$home_title = \'Homepage\';
// Get the query & post information
global $post,$wp_query;
echo \'<style>
#breadcrumbs{
list-style:none;
margin:10px 0;
overflow:hidden;
}
#breadcrumbs li{
display:inline-block;
vertical-align:middle;
margin-right:15px;

#breadcrumbs .separator{

echo \'<li class="item-current item-archive"><strong class="bread-current bread-archive">\' . post_type_archive_title($prefix, false) . \'</strong></li>\';
} else {
// Standard page
if( $post->post_parent ){
// If child page, get parents
$anc = get_post_ancestors( $post->ID );
// Get parents in the right order
$anc = array_reverse($anc);
// Parent page loop
if ( !isset( $parents ) ) $parents = null;
foreach ( $anc as $ancestor ) {
$parents .= \'<li class="item-parent item-parent-\' . $ancestor . \'"><a class="bread-parent bread-parent-\' . $ancestor . \'" href="\' . get_permalink($ancestor) . \'" title="\' . get_the_title($ancestor) . \'">\' . get_the_title($ancestor) . \'</a></li>\';

这东西是经过测试的。在我当地的环境中，它运行得很好。
希望以上答案对您有所帮助。
