CB code field usage

Hi,

I am using the CB Code field to display a calculated value.

My requirement is to use the value from a drop-down field, and populate a Code field with a calculated value.

I use the following code in the Code field.

This is the drop-down field name "cb_no_sponsored_members_pii". Based on the value selected in this field, code field should change. The code is returning the value 20500 which is returned when the $person variable is not assigned correctly.

I was following the tutorial for CB Code Fields in the site.

Can you tell me what is the problem with my code?

My main requirement is a variable subscription price. I am using the Promotions to implement this.

Your PHP is working exactly as you've coded it. If cb_no_sponsored_members_pii doesn't have a value then $p is just 10 and the reset of your math is multiplying by 10 as coded. If cb_no_sponsored_members_pii does have a value and it's still doing that then it's not finding a field with the name or the field value isn't numeric. You can use substitutions in your code though so the below could be used for example.

Hi krileon

I tried using the code provided by you. You are right that the calculation is done based on the filed [cb_no_sponsored_members_pii] value is 0.

This field is a drop down box and on loading initially the value is unset. When the user fills in this field, the calculation should happen and the Code field should be updated to reflect the new amount.

I have seen an Update On option for Query Dropdown, which gets updated dynamically based on another field. I want something similar to happen here.

Is it possible?

Thanks.

There is no functionality for that.

Such a feature does not exist. Eventually CB Core Fields Ajax will be able to do Update On on any fieldtype, but for now it can't.
