我试图更改文件的上传目录，当它通过前端使用pods上传时。

如何使用pods检查上传是否来自高级内容类型？

模板视图页面。php

$pod_name = pods_v( 0, \'url\');
$pods = pods( $pod_name, $slug );
$fields = array( \'name\', \'file\' ); 
echo $pods->form( $fields ); 

add_filter(\'upload_dir\', \'change_upload_dir\');
function change_upload_dir( $param ){

$pod_name = pods_v( 0, \'url\');
if ($pod_name == "paperwork") {
    $mydir = \'/paperwork\';
}

else {
    $mydir = \'/notpaperwork\';
}

$param[\'path\'] = $param[\'path\'] . $mydir;
$param[\'url\'] = $param[\'url\'] . $mydir;

return $param;
