我知道有很多解决方案，如何在上传文件到postid时重命名附件。我得到了真正有效的正确解决方案是：https://wordpress.stackexchange.com/a/30767/86517 (I\'m new and I can\'t comments there. So I ask this question.)
The code is:
add_action(\'add_attachment\', \'rename_attacment\');
function rename_attacment($post_ID){
$post = get_post($post_ID);
$file = get_attached_file($post_ID);
$path = pathinfo($file);
//dirname = File Path
//basename = Filename.Extension
//extension = Extension
//filename = Filename
$newfilename = "NEW FILE NAME HERE";
$newfile = $path[\'dirname\']."/".$newfilename.".".$path[\'extension\'];
rename($file, $newfile);
update_attached_file( $post_ID, $newfile );
}
但问题是，我只想更改3种自定义帖子类型。目前我的网站有6个自定义帖子类型。所以只有3个自定义帖子类型需要这个。是否有任何方法允许仅针对那些自定义帖子类型运行此函数？
谢谢

我真的很抱歉。我在发布这个问题几分钟后解决了我的问题。所以我在这里添加了我的工作代码，以便将来有人需要时提供帮助。
add_action(\'add_attachment\', \'rename_attacment\');
function rename_attacment($post_ID){
if ( get_post_type( $_REQUEST[\'post_id\'] ) === \'post_type_1\' OR get_post_type( $_REQUEST[\'post_id\'] ) === \'post_type_2\' OR get_post_type( $_REQUEST[\'post_id\'] ) === \'post_type_3\' ){
$post = get_post($post_ID);
$file = get_attached_file($post_ID);
$path = pathinfo($file);
//dirname = File Path
//basename = Filename.Extension
//extension = Extension
//filename = Filename
$newfilename = "NEW FILE NAME HERE";
$newfile = $path[\'dirname\']."/".$newfilename.".".$path[\'extension\'];
rename($file, $newfile);
update_attached_file( $post_ID, $newfile );
}
}
谢谢大家。

更简单（&A）；开发人员友好的代码
add_action(\'add_attachment\', \'rename_attacment\');
function rename_attacment($post_ID){
//get post type
$post_type = get_post_type($post_ID);
//if not in allowed post types then return
$allowed_post_types = array(\'post_1\',\'post_2\',\'post_3\');
if(!in_array($post_type,$allowed_post_types)){
return;
}
$post = get_post($post_ID);
$file = get_attached_file($post_ID);
$path = pathinfo($file);
//dirname = File Path
//basename = Filename.Extension
//extension = Extension
//filename = Filename
$newfilename = "NEW FILE NAME HERE";
$newfile = $path[\'dirname\']."/".$newfilename.".".$path[\'extension\'];
rename($file, $newfile);
update_attached_file( $post_ID, $newfile );
}
