[wp-hackers] Need help with: coding new Plugin options

Yeah, I'm forced to agree there. I just tested that generator, and
this is what it gave me:

function getAdminOptions() {
	$adminOptions = array("optionName" => "Value",
		"optionName2" => "Value",
		"optionName3" => "Value");
	$savedOptions = get_option($this->adminOptionsName);
	if (!empty($savedOptions)) {
		foreach ($savedOptions as $key => $option) {
			$adminOptions[$key] = $option;
	update_option($this->adminOptionsName, $adminOptions);
	return $adminOptions;

That's just poor practice, man. Here's a better way:

function getAdminOptions() {
	return get_option($this->adminOptionsName, array(
		// default option values follow
		"optionName" => "Value",
		"optionName2" => "Value",
		"optionName3" => "Value"

Simple, no? Look, this function is just  supposed to get the options,
correct? So why is it writing anything to the database at all, ever?
The default values don't need to be in the database until they are
altered or saved. Then it can update them. The rest of the time, as
long as the plugin loads its options using getAdminOptions there, then
it will always get either the options from the DB or the defaults. Who
cares where they come from?
