at first you have to edit init.php

there you will find this codeblock:

PHP Code:

// 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,
); 


you can add more options there, you just have to make sure, that your values, are 2 ^x and bigger than the currently existing ones, so in your special case here, i suggest something like:

PHP Code:

// 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,
    'tosagree'        =>  1048576,
); 


and then instead of:

PHP Code:

$DB_site->query("update user set tos = 'y' where userid='$user[userid]'"); 


you have to use:

PHP Code:

$DB_site->query("UPDATE user SET options = options | $_USEROPTIONS[tosagree] WHERE userid = $user[userid]");
