You want to use variable variables. You may have to play with this to get
it to work exactly, but
I would add a hidden field
echo "<Input Type=Hidden Name=named value=\"$ai_info[0]\">";
That way $named = {The name of your checkbox}
Then to access your checkbox just use ${$named}
for example
if ( ${$named} == 1)
{
echo "foo";
}
