About Options in theme and plugin…

Hello.

I develop a theme with options and I have two questions:

– To call the variables stored in wp-options in my theme, is it mandatory to indicate in each page (header, index, searc, single …) the following code:

<?php
global $options;
foreach ($options as $value)
{
	if (get_settings( $value['id'] ) === FALSE)
	{
		$$value['id'] = $value['std'];
	}
	else
	{
		$$value['id'] = get_settings( $value['id'] );
	}
}
?>

– On the contrary, to call the variables stored in wp-options in a plugin, do I enter a query to each or can I call once and for all these values, as in the previous case?

Thank for your help.
