我发现了这个代码，我认为这是一个好主意：
add_filter( \'post_link\', \'remove_parent_cats_from_link\', 10, 3 );
function remove_parent_cats_from_link( $permalink, $post, $leavename )
{
$cats = get_the_category( $post->ID );
if ( $cats ) {
// Make sure we use the same start cat as the permalink generator
usort( $cats, \'_usort_terms_by_ID\' ); // order by ID
$category = $cats[0]->slug;
if ( $parent = $cats[0]->parent ) {
// If there are parent categories, collect them and replace them in the link
$parentcats = get_category_parents( $parent, false, \'/\', true );
// str_replace() is not the best solution if you can have duplicates:
// myexamplesite.com/luxemburg/luxemburg/ will be stripped down to myexamplesite.com/
// But if you don\'t expect that, it should work
$permalink = str_replace( $parentcats, \'\', $permalink );
}
}
return $permalink;
}
但我有个麻烦。它不适用于此结构：
www.domain.com/taco/promotions-taco/2014/title-post/
它变成：
www.domain.com/promotions-2014/title-post/ （为什么？）
但我想要这样的结构：
www.domain.com/promotions-taco/2014/title-post/
有可能吗？
