Creating shortcodes with user created forms

Question

I am creating a plugin. That enables users to create forms, & display these with shortcodes on a site. When creating a form (using custom post types), users will be able to add additional form fields with meta boxes.

My question: When a user creates a form (via custom post type), how do I store the field type so the shortcode knows which type to display for the form?

Answer 1

Store each field the user creates as an array in a post meta field, the array would contain the name and a reference to the field type. You could also store additional data within the array, like if it's required and the type of validation to apply.
