It was brought to my attention recently that when using the ACF forms, the file attachment (image) is saved to the media gallery. Since we are also getting a copy of this file emailed, is there a good way to delete the attachments after the form is submitted?
What plugin are you using to email submissions for front end forms? You need to contact the developer of that plugin.
If you are not using a plugin then what code is used to cause the form submission to be emailed?
