Re: Multiple Select Stuff

That's a good though. I've always done nested for loops to do multiple select boxes. What about doing the same thing, but using the in_array function, to do the same thing? if (in_array('def', $array)) I've never used it, but looks like it would work. If it does, let me know, cause I'm gonna start using it. :) ----- Original Message ----- From: "John Coggeshall" <someone@internetaddress.com> To: "Joe Conway" <jconway2@home.com> Cc: "php general" <php-general@lists.php.net> Sent: Saturday, August 05, 2000 12:44 AM Subject: RE: [PHP] Multiple Select Stuff > > You've got the right idea, and yes the select box is multiple-select.
