Problem by adding new page with PageTable field via API

[diegonella]

I am using the following code:

$new_pt = new Page();

$new_pt->parent			= "/opt/";

$new_pt->template		= "pt_template";

$new_pt->name			= uniqid('pt-', true);

$new_pt->title			= "Title ".time();


if ( $new_pt->save()) {

	$page->of(false);

	$page->pt_field->add($new_pt);

	$page->save();

}

and it turns out I inserted 2 pages, and I can not know where the problem.

I'm using 2.6.1 PW

Could give me a help, where my error.

thanks
