Question

I have a form, which contains multiple virtual fieldsets.

Eg, MyForm:

Name1
Age1
Location1

Name2
Age2
Location2

Name3
Age3
Location3

Submit

If I allow the user to dynamically create more field sets on the client how can I loop through all fieldsets where name(x) is set and perform an similar action for each group, using the integer (1,2,3 etc) as a unique identifier?

I want to specify the actions once, loop through and each time change the variables used according to the number of the fieldset.

Right now, I am doing it manually for 3 hardcoded fireldsets, but it won’t scale:

Pseudocode:

if($name1 is set) {
do something using $age1 and $location1
}
if($name2 is set) {
do something using $age2 and $location2
}
if($name3 is set) {
do something using $age3 and $location3
}

Thanks!

Do it like this:

    $maxIndex = 3

    for(var $i=1; $i<=$maxIndex; $i++){
       $name = $_POST["Name$i"];
       $age = $_POST["Age$i"];
       $location = $_POST["Location$i"];
       //do something using $name, $age and $location
    }

Hope this helps. Cheers
