WordPress去除固定链接中的子分类标签

新主题的WordPress固定链接格式是:/%category%/%post_id%.html(分类名/文章ID.html)

但是我有的分类下有很多子分类,那么文章链接就会变成:http://www.xintheme.com/父分类/子分类/文章ID.html

这样的话链接目录层次就有点深,从某种方面来讲不太利于SEO优化,然后就要想办法干掉WordPress固定链接中的子分类了,把下面的代码添加到WordPress主题中的functions.php里面:

[php]// wordpress 去掉固定链接中的子分类http://www.xintheme.com/theme/blog/2294.html
//去掉后: http://www.xintheme.com/theme/2294.html
add_filter('post_link','custom_post_type_link',10,3);
function custom_post_type_link($permalink, $post, $leavename) {
if (!gettype($post) == 'post') {
return $permalink;}
switch ($post->post_type) {
case 'post':
//$permalink = get_home_url() . '/' . $post->post_name . '/';
$cats = get_the_category($post->ID);
$subcats = array();
foreach( $cats as $cat ) {
$cat = get_category($cat->term_id);
//if($cat->parent) { $subcats[] = sanitize_title($cat->name);
if($cat->parent) { $subcats[] = $cat->slug;}}
if($subcats) {
foreach($subcats as $subcat) {
$subcat = $subcat.'/';
$permalink = str_replace($subcat, "", $permalink);}}
break;}
return $permalink;} [/php]

多级分类解决方法:

[php]// wordpress 去掉固定链接中的所有子分类包含孙分类http://www.xintheme.com/theme/blog/ceshi/2294.html
//去掉后: http://www.xintheme.com/theme/2294.html
function remove_child_categories_from_permalinks( $category ) {
while ( $category->parent ) {
$category = get_term( $category->parent, 'category' );
}
return $category;
}
add_filter( 'post_link_category', 'remove_child_categories_from_permalinks' );[/php]
