CB Code Field

Hi,
I have 2 questions:
1. where to find "Update on" option in the CB Code as there is no documentation at all?
2. I'm trying to achieve:
- during the registration unique 8 digit number generated used for membership payment
- remain this number and do not allow to the user change it at all

I was trying to generate number using PHP, but when checking strlen(cb_myfield) -- the code field itself - it always returns 0 so the code is always executed.
I can generate unique number based on the email address, but the code field needs to be updated dynamically once email address is entered - I don't see the "Update on" option.
Or is there any easy way how to generate unique number for the user just once?

thanks

1. where to find "Update on" option in the CB Code as there is no documentation at all?

Update On is deprecated in CB Code Field. Use the Update On feature in CB Core Fields Ajax as it can work with any fieldtype.

Or is there any easy way how to generate unique number for the user just once?

They already have a unique number via [user_id]. Aside from that yes you can use a CB Code Field, but you don't need the Update On usage for it. Suggest generating a unique number based off the user id, which will never change. Could be as simple as an md5 of user id + a secret key. Example as follows.


Replace SECRET_KEY with something only you would know or at least something not easily guessed.

Thanks, will give a try. One thing on the code - it will work only for existing users, right? So it can't be used during registration.

the thing I want to achieve is to generate a 8 to 10 digit which will be used for bank wire transfer / payment identification during the registration process.

Correct.

You may want to consider using CBSubs in that case to accept online payments. Stripe gateway supports ACH Credit Transfers, which are just wire transfers.

If they don't need to send payment at same time as registration you could just provide them their ID number (your code field) after they've registered, which will work fine. This likely could just be a part of the registration complete message shown after registering using language overrides feature below to override it and add your code field to it.
