Tell us what you are trying to do? I would like for a member to type a number (in a certain range) and the system to check whether that number is available. For example, the member is interested in purchasing number 1234 by entering this value in the cred form, the system needs to confirm availability.
Is there any documentation that you are following?
Is there a similar example that we can see?
What is the link to your site?
Hi,
Thank you for contacting us and I'd be happy to assist.
There is no built-in field available in the forms that can be used for the Ajax Lookup. But, there is a workaround that can be used.
You can register a new custom post type 'Numbers' and add a form that creates a new 'Number' post.
In that form, you can include a custom validation function attached to the 'cred_form_validate' hook, that ensures that a number post with the same 'title' can't be created again.
( ref: https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_validate )
This way if the user will try to create a number post with the title that is already taken, the validation message will show, asking to enter a different number.
You'll find an example of a similar validation function, in this forum reply:
