So, in short, the problem is unchecked checkboxes don't get send, which =
is =
default behaviour);
Solution:
Checkbox name: "shows[]"
Text names: "people[<show_value>]" (so: people[Morning], people[Lunch] =
=
etc.)
(Oh yeah: and get rid of your unopened </options>'s... validate your HTM=
L =
:-) )
Receiving end:
foreach($_POST['shows'] as $show){
$num =3D isset($_POST['people'][$show]) ? intval($_POST['people'][$sho=
w]) =
: 0;
echo "$num people for $show show";
}
However, is there a special need to have both a checkbox AND a textfield=
? =
Surely this is double work for your users, and they can just leave a tex=
t =
field blank if they don't choose that option?
