我有一个名为海滩的自定义帖子类型。每次创建帖子时都会创建一个类别,这是有效的。
我的类别与帖子类型具有相同的标题和相同的slug。
问题是当帖子更新时,如果标题和段塞发生变化,我就不能再将帖子链接到该类别。
此代码可用于创建类别:
function rci_custom_dynamic_beach_category ($post_id) {
$post = get_post($post_id);
if($post->post_status === 'auto-draft') return;
if($post->post_type !== 'beaches') return;
// Verify if the category exists already
$exist = term_exists($post->post_name, 'beaches');
if($exist !== 0 && $exist !== null) {
// THE PROBLEM IS HERE
// Get the category by the slug field
$term = get_term_by('slug', $post->post_name, 'beaches');
wp_update_term($term->term_id, 'beaches', array(
'name' => $post->post_title,
'slug' => $post->post_name
));
}
else {
wp_insert_term($post->post_title, 'beaches', $args = array(
'slug' => $post->post_name,
'parent' => 'houses'
));
}
}
add_action('save_post', 'rci_custom_dynamic_beach_category');
有没有办法获得旧的slug值,以便在更新后使用新值找到该术语?
