- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
如果有更好的方法可以做到这一点,请原谅我,因为我对这段代码不是很熟悉。我只想在面包屑上显示主页和当前产品的链接。

我找到了面包屑的代码,有没有办法只显示第一个和最后一个面包屑而不管层次结构?
foreach ( $breadcrumb as $key => $crumb ) {
echo $before;
if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key ) {
echo '<a href="' . esc_url( $crumb[1] ) . '">' . esc_html( $crumb[0] ) . '</a>';
} else if(!is_product() && !flatsome_option('wc_category_page_title')) {
echo esc_html( $crumb[0] );
}
echo $after;
// Single product or Active title
if(is_product() || flatsome_option('wc_category_page_title')){
$key = $key+1;
if ( sizeof( $breadcrumb ) > $key) {
echo ' <span class="divider">'.$delimiter.'</span> ';
}
} else{
// Category pages
if ( sizeof( $breadcrumb ) !== $key + 1 ) {
echo ' <span class="divider">'.$delimiter.'</span> ';
}
}
}
我这样做的原因是一些产品有多个类别,默认情况下,它只会显示主要类别的面包屑。我宁愿按照所有者的建议制作一个截断版本。
最佳答案
如果您想从产品面包屑中删除类别和子类别 在产品页面上,您可以使用 woocommerce_get_breadcrumb
钩。
// change the breadcrumb on the product page
add_filter( 'woocommerce_get_breadcrumb', 'custom_breadcrumb', 20, 2 );
function custom_breadcrumb( $crumbs, $breadcrumb ) {
// only on the single product page
if ( ! is_product() ) {
return $crumbs;
}
// gets the first element of the array "$crumbs"
$new_crumbs[] = reset( $crumbs );
// gets the last element of the array "$crumbs"
$new_crumbs[] = end( $crumbs );
return $new_crumbs;
}

_yoast_wpseo_primary_product_cat
product meta 设置主要产品类别的 id。
After setting the primary category id by editing the product in thebackend or importing a .csv file you will only need to change thepermalink and breadcrumbs based on the primary product category.
// update the product permalink based on the primary product category
add_filter( 'wc_product_post_type_link_product_cat', 'change_product_permalink_by_cat', 10, 3 );
function change_product_permalink_by_cat( $term, $terms, $post ) {
// get the primary term as saved by Yoast
$primary_cat_id = get_post_meta( $post->ID, '_yoast_wpseo_primary_product_cat', true );
// if there is a primary and it's not currently chosen as primary
if ( $primary_cat_id && $term->term_id != $primary_cat_id ) {
// find the primary term in the term list
foreach ( $terms as $term_key => $term_object ) {
if ( $term_object->term_id == $primary_cat_id ) {
// return this as the primary term
$term = $terms[ $term_key ];
break;
}
}
}
return $term;
}
更新产品面包屑 在产品页面上:
// change the breadcrumb on the product page
add_filter( 'woocommerce_get_breadcrumb', 'custom_breadcrumb', 20, 2 );
function custom_breadcrumb( $crumbs, $breadcrumb ) {
// only on the single product page
if ( ! is_product() ) {
return $crumbs;
}
global $product;
$new_crumbs = array();
if ( $product->get_meta( '_yoast_wpseo_primary_product_cat', true ) ) {
// gets the first element of the array "$crumbs"
$new_crumbs[] = reset( $crumbs );
// gets the id of the primary product category
$primary_cat_id = $product->get_meta( '_yoast_wpseo_primary_product_cat', true );
// create an array with all parent categories (based on the id of the primary product category)
$parent_categories = get_ancestors( $primary_cat_id, 'product_cat' );
$parent_categories = array_reverse($parent_categories);
$parent_categories[] = $primary_cat_id;
// for each product category it gets the name and the permalink
foreach ( $parent_categories as $cat_id ) {
$term = get_term_by( 'id', $cat_id, 'product_cat' );
$new_crumbs[] = array(
0 => $term->name,
1 => esc_url( get_term_link( $term, 'product_cat' ) )
);
}
// gets the last element of the array "$crumbs"
$new_crumbs[] = end( $crumbs );
} else {
// gets the first element of the array "$crumbs"
$new_crumbs[] = reset( $crumbs );
// gets the last element of the array "$crumbs"
$new_crumbs[] = end( $crumbs );
}
return $new_crumbs;
}
