Tell us what you are trying to do?
We have an email field which we don't want to allow any duplicates of the field value. IE only one post can be submitted with that email address.

Is there any documentation that you are following?
Couldn't find anything related to this.

Is there a similar example that we can see?

What is the link to your site?

Hello. Thank you for contacting the Toolset support.

Do you mean that you are using Toolset form and with that form you want to check before post get saved that if the email is already registered it should ask user to add another email. If yes:
- You can use Toolset Form hook: cred_form_validate

Please check the following realted ticket where I shared the related solution.
