user table option field

[spiderweb]

I currently send a newsletter to all registered users (I use a odbc connection from my email server to select usergroupid = 2 from the users table)

But I would like to use the Receive Email from Administrators option to turn on / off my sites newsletter so members can opp out. I see that adding 16 allows admin emails and minus turns off the option but I see a lot of odd numbers in that field.

Is there a reference to the way the options field works?

See this thread.

The user option bits are defined in the includes/init.php file:

// Defined constants used for user field.
$_USEROPTIONS = array(
	'showsignatures'    => 1,
	'showavatars'       => 2,
	'showimages'        => 4,
	'coppauser'         => 8,
	'adminemail'        => 16,
	'showvcard'         => 32,
	'dstauto'           => 64,
	'dstonoff'          => 128,
	'showemail'         => 256,
	'invisible'         => 512,
	'showreputation'    => 1024,
	'receivepm'         => 2048,
	'emailonpm'         => 4096,
	'hasaccessmask'     => 8192,
	//'emailnotification' => 16384, // this value is now handled by the user.autosubscribe field
	'postorder'         => 32768,
);
