Is it possible to make a conditional field based on previous selections in another field?

For instance, I have added a new field group, let's call it Field Group B.

In Field Group B I place a field called "membership level" and base it on whether or not they have checked the following in field2:

Field 2: "Options" (checkbox - with multiple selections enabled) says:
1) basic membership
2) added listing: $5.00
3) added certificate $5.00

If 1) only, then "basic membership" in the field "membership level"
If 1+2, then "membership level 2" in the field "membership level"
If 1+2+3, then "membership level 3" in the field "membership level"

That way they can sign up as basic and let add the other stuff for a fee that they will pay offline.

Is that even possible?

Hi and sorry for late reply.

This seems possible. If you want to assign a value in the another field then you can write a simple plugin, follow these steps:
- Download, Install and Enable Skeleton Plugin (you will find it at
- Open file /plugins/jsn/skeleton/skeleton.php
- remove samples functions: triggerFieldAvatarUpdate, triggerProfileUpdate
- add function like this:
public function triggerProfileUpdate($user,&$data,$changed,$isNew){ 
$field2 = (array) json_decode($data['field2alias']); // "field2alias" is the alias of Field 2
if(in_array("1", $field2)) $data['membership_level'] = 'basic membership';
if(in_array("1", $field2) && in_array("2", $field2)) $data['membership_level'] = 'membership level 2';
if(in_array("1", $field2) && in_array("2", $field2) && in_array("3", $field2)) $data['membership_level'] = 'membership level 3';

sorry but I have not understood well :(

Do you want to show "membership_level" field in edit profile page or in profile page? which type of field is "membership_level"?
Basically for me it's not cleat the purpose of the field "membership_level".
