Hi,
Yes you can do this, but you will write simple plugin based on our Skeleton plugin.
here a plugin and documentation of our Triggers
https://www.easy-profile.com/docs/44-triggers.html
You can do something like this:
- Download, install, and enable our Skeleton plugin
- Go on file /plugins/jsn/skeleton/skeleton.php
- delete examples functions triggerFieldAvatarUpdate and triggerProfileUpdate
- write a function like this
triggerProfileUpdate($user,&$data,$changed,$isNew){
$data['field3']=$data['field1']*$data['field2'];
}
NOTE: this code is not tested and not supported and require minimum PHP knowledge
