I have created a CRUD System using ACF Pro V. 5 and I have a custom post type named certificates which in turn has its own custom fields created with acf.
Then I used the handy acf_form() to create a front end form and it works perfectly. However, I would like to persist the data of the last form when I create a new certificate in the front end form. Is this posible?
Then to load the last values into the form when a new form is loaded you can use an acf/load_field filter. http://www.advancedcustomfields.com/resources/acfload_field/. The example shows changing field choices, but this can be used to change any ACF field argument. You can use this filter to change the default value of the field to match the last saved value.
