我在我的临时站点上格式化面包屑时遇到了问题。我之前用正确的类别设置了它们,但父类别一直显示错误的类别(我确实修复了,但是...)。修复导致"home“选项消失。我不知道任何php,并且一直试图弄清楚如何在每个页面的类别前添加一个"Home /“选项,但没有成功。下面是我现在使用的代码。有谁有什么想法吗?
if ( ! empty( $breadcrumb ) ) {
echo $wrap_before;
if ( is_single() && get_post_type() == 'product' ) {
echo $prepend;
if ( $terms = get_the_terms( $post->ID, 'product_cat' ) ) {
$referer = wp_get_referer();
$printed = array();
foreach( $terms as $term){
if(in_array($term->id, $printed)) continue;
$referer_slug = (strpos($referer, '/'.$term->slug.'/'));
if(!$referer_slug==false){
$printed[] = $term->id;
$category_name = $term->name;
$ancestors = get_ancestors( $term->term_id, 'product_cat' );
$ancestors = array_reverse( $ancestors );
foreach ( $ancestors as $ancestor ) {
$ancestor = get_term( $ancestor, 'product_cat' );
if ( ! is_wp_error( $ancestor ) && $ancestor )
echo $before . '<a href="' . get_term_link( $ancestor->slug, 'product_cat' ) . '">' . $ancestor->name . '</a>' . $after . $delimiter;
}
echo $before . '<a href="' . get_term_link( $term->slug, 'product_cat' ) . '">' . $category_name . '</a>' . $after . $delimiter;
}
}
}
echo $before . get_the_title() . $after;
} else {
foreach ( $breadcrumb as $key => $crumb ) {
echo $before;
if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key + 1 ) {
echo '<a href="' . esc_url( $crumb[1] ) . '">' . esc_html( $crumb[0] ) . '</a>';
} else {
echo esc_html( $crumb[0] );
}
echo $after;
if ( sizeof( $breadcrumb ) !== $key + 1 ) {
echo $delimiter;
}
}
}
echo $wrap_after;
}提前感谢您的帮助!

我认为您可以通过将以下行的echo $wrap_before;更改为以下代码来实现此目的:
echo $wrap_before.'<a href="/" title="Home">Home</a> »';https://stackoverflow.com/questions/59699207
