To add the action to any form, click Add New Action and then the Record Submission action from inside the Actions Window that opens.
Under the action there is an option to designate the Submitter’s Email Address. This is used to associate the submission with a user so their submission will be included in data export and delete requests for GDPR.
You can also designate the fields to be saved in the submission. Save All saves all the submission data minus the fields that you specify under the Except section. Save None does not save any submission data except for the fields that you specify under the Except section.
Under the Advanced Settings of the Record Submission Action, you can set the option for the submissions to expire after a set amount of time after the submission. When the submissions expire, they will be deleted. This setting applies to all submissions associated with the form that it is set on and also applies to all previous submissions from that form that are older than the amount of days set.
The action can be enabled or disabled using the toggle. WARNING: With no Record Submission action ENABLED on the form (toggle is set to the right), submissions for this form WILL NOT be recorded under Ninja Forms > Submissions
