I was wondering if it was possible to clean solution to prevent a specific metabox id from finalising and creating a new post after successful validation. I ask as I wanted to create a basic contact form and wanted to avoid using another plugin when all of the fields are there in metabox. So once the form is submitted you can send emails using form actions and then avoid storing the data as a post.
Yes that is correct in regards to the save posts (data). I did not want to create a custom form ideally as Metabox already has the functionality and before and after form submission actions. So saves alot of dev work as i may need more forms in the near future.
