New add_settings_field question

Hi all!

I’m amazed with this new add_settings_field thing. That’s awesome!!

But I’m trying to figure out how to pass an argument to the callback function. Actually, I don’t know if it could be done ??

Eg.

$as = array('A', 'B', 'C', 'D');
$adb = null;

function my_new_settings(){
	global $as;
	foreach($as as $a):

		$adb = sanitize_title($a);		

		register_setting('media',"{$adb}_1");
		register_setting('media',"{$adb}_2");

		add_settings_field("{$adb}" , "{$a} setting:" ,
			'my_new_callback' , 'media' , 'default');

	endforeach;
}

function my_new_callback(){
	global $adb;

	echo "<label for=\"{$adb}_1\">Setting 1</label>
		<input name=\"{$adb}_1\" id=\"{$adb}_1\" value=\"".attribute_escape(get_option("{$adb}_1"))."\" class=\"small-text\" type=\"text\">
		<label for=\"{$adb}_2\">Setting 2</label>
		<input name=\"{$adb}_2\" id=\"{$adb}_2\" value=\"".attribute_escape(get_option("{$adb}_2"))."\" class=\"small-text\" type=\"text\">
	";
}

add_action('admin_init', 'my_new_settings');

Could anyone help here?

Thanks in advance!
n!
