新主題的WordPress固定鏈接格式是：/%category%/%post_id%.html（分類名/文章ID.html）

但是我有的分類下有很多子分類，那么文章鏈接就會變成：http://www.fzschg.com/父分類/子分類/文章ID.html

這樣的話鏈接目錄層次就有點(diǎn)深，從某種方面來講不太利于SEO優(yōu)化，然后就要想辦法干掉WordPress固定鏈接中的子分類了，把下面的代碼添加到WordPress主題中的functions.php里面：

[php]// wordpress 去掉固定鏈接中的子分類http://www.fzschg.com/theme/blog/2294.html
//去掉后： http://www.fzschg.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]

多級分類解決方法：

[php]// wordpress 去掉固定鏈接中的所有子分類包含孫分類http://www.fzschg.com/theme/blog/ceshi/2294.html
//去掉后： http://www.fzschg.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]
