Pardon my following up to myself, but I figured it'd be a good idea to
do so. I was initially going to suggest your method of coding seems
quite wacky. Then, I figured, hey, let them do what they want. Now,
I've thought better of it. A far simpler way to achieve what it seems
you're trying to do is to use an array in the first place.
<input type="checkbox" name="checkbox['Name']" value="validate" />
Then in your receiving code, you could just do
if ($checkbox['Name'] == 'validate') {
Or, if you want to loop through each item, as you were in your original
code:
while ( list($Key,$Val) = each($checkbox) ) {
if ($Val = 'validate) {
$msg .= "$Key : $Val\n";
# or whatever it was you were trying to do...
}
}
WAY cleaner and WAY more flexible. Now you can add new items to the
form without having to name them in your $cb[] array.
Also, FYI, there was no need to set the array using $cb[$i]. Just
doing something like
$cb[] = 'some value'; works just fine, with the key being
automatically numbered/incremented, starting at 0.
Enjoy,
