Checkboxs

[dkin]

Hi,

I have a php script that generate a dynamic number of checkbox with different names (depend on the user input, min.=0 max.=150). Is their way to know which of the checkbox had been clicked without running isset on each of the possibilities?

Thanks.

Well not that i know of. But what do you need the checkboxes for.

Unless you want multiple answers which is what im thinking you want, why not use radiobox.

Yes, I want multiple answers and with radio button I can only click radio button once and after it I can not unclick it.

ok you will need to list all the variables in an array eg.

$form_vars[0] = $_POST['hello'];
$form_vars[1] = $_POST['merry'];
$form_vars[3] = $_POST['xmas'];
//and so on

//then you will need a for function
$vars = sizeof($form_vars);
for($i=0; $i<$vars; $i++){
if(!isset($form_vars[$i])){
die("Graceful error message");
}
}
