say, I have a field of checkboxes in 3 columns and 6 rows. I need at least
At the moment every checkbox has the name of kind: q3_4_1 , where 4 stands
for row and 1 for column. Now, how do I name them and loop through them?
Plus, if $HTTP_POST_VAR["q3_4_1"] wasn't checked at all, the value is not
passed over, right? So I get... null, I believe. So with my eval I first do
if(isset()) and then go on. How would I I behave in your case?
Please, John, if you could be even more specific?....
