我正在使用此解决方案从我的博客文章的网址中删除子类别: Remove sub category slug from permalink URL of blog post and custom post type in WordPress
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($subcats) {
foreach($subcats as $subcat) {
$subcat = $subcat.'/';
$permalink = str_replace($subcat, "", $permalink);
}
}
break;
}
return $permalink;}
它工作正常,但是代码仍然存在一些问题。
如果我有这样的网址:
www.myblog.com/parentcategory/ 子类别的名称 / slugpost
我会得到这个:
www.myblog.com/parentcategory/slugpost
这正是我想要的。
但是,如果我有这样的网址:
www.myblog.com/parentcategory/ 子类别的名称 / slugpost-with- 子类别的名称
我会得到这个:
www.myblog.com/parentcategory/slugpost-with- (提示子弹的末尾)
...以及指向本文的每个链接的404页。
所以问题在于,当子类别文本出现在子句的帖子中时,代码还将删除URL的这一部分。
有人知道如何解决这个问题吗?
谢谢!

尝试划定弹头的两端,例如:
foreach ($subcats as $subcat) {
$permalink = str_replace('/'.$subcat.'/', '/', $permalink);
}

我找到了这个解决方案,添加了两个功能。我不确定代码是否是最佳代码,但是否能完美工作。
add_filter('post_link','custom_post_type_link',10,3);
//function to see if URL ends with...
function endsWith($string, $endString) {
$len = strlen($endString);
if ($len == 0) {
return true;
}
return (substr($string, -$len) === $endString);
}
//function to replace only first match
function str_replace_first($from, $to, $content)
{
$from = '/'.preg_quote($from, '/').'/';
return preg_replace($from, $to, $content, 1);
}
function custom_post_type_link($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($subcats) {
foreach($subcats as $subcat) {
$subcat = $subcat.'/';
//If URL ends with category name
if(endsWith($permalink,$subcat)){
//And if the category name appears more than once
if(substr_count($permalink,$subcat)>1){
// Remove only first match
$permalink = str_replace_first($subcat, "", $permalink);
}else{
//do nothing
}
}
// If URL does NOT end with category name
else{
$permalink = str_replace($subcat, "", $permalink);
}
}
}
break;
}
return $permalink;}
