How to restrict submission of duplicate entry of a custom post type by a user using toolset forms? For example your example site there a post type called events and another post type called venues. Now if anyone is going to submit a venue using toolset form and if the location the venue( google map location) is already exists as a venue in the venue archive then how to restrict that submission?
Hello. Thank you for contacting the Toolset support.
You can use the Toolset form's hook "cred_form_validate" to add validation for your form.
I would like to inform you that the Toolset map address field value is stored as post meta value to the postmeta table and it will be required for posts.
If your requirement is that a person X created entry with location Chicago and you do not want another person to add Chicago then you should check for validation but please note that "Chicago" and "Chicago, Illinois" will be different in comparison so you will have to make sure that there should not be duplicates.
