I forgott to tell you, how to use those settings in you mod.
For both options, you will get back an array (serialized). First unserialized the value
PHP Code:
// unserialized the value
$vbulletin->options['multiinput_choose'] = unserialized ($vbulletin-options['multiinput_choose']);
// unserialized the value
And next is to check the array.
PHP Code:
if (in_array ('findme', $vbulletin->option['multiinput_choose']))
{
// I found "findme"
// ... let's do some code
}
