Creating a folder when registering via Theme my login?

Question

WordPress

I’ve already found everything, I can’t achieve a result on the Theme my login plugin, it works on others, but I want it on this one!
Bottom line: after registering a user, a folder with a user ID should be created.
Tell me where to add the line
mkdir("./$user_id", 0700);
to Theme my login plugin

Answer 1

no need to insert anything into any plugin.
It is enough to hang on the 'user_register' hook

function wpp_create_dir_for_user( $user_id ) {
      
    $upload_dir = wp_upload_dir();
    $user_dir   = sprintf( '%s/users/%s', $upload_dir[ 'basedir' ], $user_id );

    wp_mkdir_p( $user_dir );
  }

  add_action( 'user_register', 'wpp_create_dir_for_user' );
