the variable $id in the second sniplet come from the id from talble when I
run query and loop it using mysql_fetch_array. So I end up have value of $id
from the id field from table, right?But the value store in $id is now in
string value, and if I need to use that value for the if..then.. else
condition to check if which checkbox is checked, I will need to use Variable
variable to make the string back to be variable again , like $$id, for
instance after I run the query and get all Id value from table, it will be
like
$id = 1, $id=2, and so on
and as I used this for checkbox name at the previous page, in order to uset
it in the if..then..else condition in the second sniplet, it will be like
if ($1=="on") {
do something
}else{
do somehting
}
but something is wrong here at the if then else bit. But I don't know what
is it.
