Modify Javascript for PHP array

[bjblackmore]

Hi,
Does anyone know how to modify this javascript so that it will recognise checkboxs called checkbox[0], checkbox[1], checkbox[2]...etc so my php script will work.

<SCRIPT LANGUAGE=&quot;JavaScript&quot;>
var checkflag = &quot;false&quot;;
function check(field) {
if (checkflag == &quot;false&quot {
for (i = 0; i < field.length; i++) {
field.checked = true;}
checkflag = &quot;true&quot;; }
else {
for (i = 0; i < field.length; i++) {
field.checked = false; }
checkflag = &quot;false&quot;; }
}
</script>

Cheers
Ben
