我刚刚挣扎了几个小时，试图处理woocommerce的面包屑，我只是看到，正常的功能是不起作用的。。

add_filter( \'woocommerce_breadcrumb_defaults\', \'custom_breadcrumb\');

function custom_breadcrumb() {
    return array(
        \'delimiter\'   => \'<li class="mx-2 text-gray-500">/</li>\',
        \'wrap_before\' => \'<ol class="breadcrumb flex text-xs uppercase text-gray-400 font-medium">\',
        \'wrap_after\'  => \'</ol>\',
        \'before\'      => \'<li class="hover:text-blue-500">\',
        \'after\'       => \'</li>\',
        \'home\'        => _x( \'Home\', \'breadcrumb\', \'woocommerce\' ),
    );
}

add_filter( \'woocommerce_breadcrumb_defaults\', function() {
    return array(
        \'delimiter\'   => \'<li class="mx-2 text-gray-500">/</li>\',
        \'wrap_before\' => \'<ol class="breadcrumb flex text-xs uppercase text-gray-400 font-medium">\',
        \'wrap_after\'  => \'</ol>\',
        \'before\'      => \'<li class="hover:text-blue-500">\',
        \'after\'       => \'</li>\',
        \'home\'        => _x( \'Home\', \'breadcrumb\', \'woocommerce\' ),
    );
} );
