Indeed, you heard somewhere that it's a nice to use the [] in =
select/checkbox names, but that's because they will autmatically generat=
e =
an array for you. Try print_r($_POST) to see what you get.
Also, drop the $ in the second part of the statements, they aren't =
variables but strings, and in the first part, quote the strings. Hmm, th=
at =
sounds somewhat hazy. Illustration:
$tcolor['red']=3D$_POST['tcolor[red]'];
Would be correct, but php has already provided something for you:
$tcolor['red']=3D$_POST['tcolor']['red'];
Or actually, in this case, everything can be replaced by:
$tcolor =3D $_POST['tcolor'];
echo 'You chose: '.implode(', ',$tcolor);
