Question

我这里有一个代码，除了woocommerce产品页面

以外工作正常

例如：

Home > category1 > category2 > category3

但是当我转到产品页面时，它只显示如下

Home > category1 > product

我需要在产品页面中显示

Home > category1 > category2 > category3 > product

我认为这是修改代码的地方（if（get_post_type（）=='product'）{}）

以下是代码：

function limelight_breadcrumbs()
{
global $post, $wp_query;
if ( ! $home ) $home = __( 'Home', 'limelight' );
$home_link = home_url();
$delimiter = ' &raquo; ';
$currentBefore = '<span class="current">';
$currentAfter = '</span>';
$wrap_before = ' <nav id="breadcrumbs">';
$wrap_after = '</nav> ';

if ( get_option('woocommerce_prepend_shop_page_to_urls') == "yes" && woocommerce_get_page_id( 'shop' ) &&   get_option( 'page_on_front' ) !== woocommerce_get_page_id( 'shop' ) )
$prepend = '<a href="' . get_permalink( woocommerce_get_page_id('shop') ) . '">' . get_the_title( woocommerce_get_page_id('shop') ) . '</a> ' . $delimiter;
else $prepend = '';

if ( ( ! is_front_page() && ! ( is_post_type_archive() && get_option( 'page_on_front' ) == woocommerce_get_page_id( 'shop' ) ) ) || is_paged() ) {

    echo $wrap_before . '<a class="home" href="' . $home_link . '">' . $home . '</a> ' . $delimiter ;

    if ( is_category() ) {

        $cat_obj = $wp_query->get_queried_object();
        $this_category = get_category( $cat_obj->term_id );

        if ( $this_category->parent != 0 ) {
            $parent_category = get_category( $this_category->parent );
            echo get_category_parents($parent_category, TRUE, $delimiter );
        }

    echo $wrap_after;

}
}

我似乎无法对此做任何事情，我不知道如何。

通过插入代码

解决了这个问题

    $taxonomy = 'product_cat'; //change to your taxonomy name

    // get the term IDs assigned to post.
    $post_terms = wp_get_object_terms( $post->ID, $taxonomy, array( 'fields' => 'ids' ) );
    // separator between links
    $separator = $delimiter;

    if ( !empty( $post_terms ) && !is_wp_error( $post_terms ) ) {

        $term_ids = implode( ',' , $post_terms );
    $terms = wp_list_categories( 'title_li=&style=none&echo=0&taxonomy=' . $taxonomy . '&include=' . $term_ids );
    $terms = rtrim( trim(  str_replace( '<br />',  $separator, $terms ) ), $separator );

    // display post categories
    echo  $terms . $delimiter;
    }

所以这将显示与产品相关的所有类别，希望我是对的...但工作正常
