Forms are used for both collecting new data, and editing existing data. In order to allow users to modify existing data you need to pre-populate the elements on the form with the data you previously stored.
In this tutorial we'll look at the ways in which forms can be pre-populated with existing data, including:
- Providing default values for form elements which a user can edit with the
#default_valueproperty - The differences between the
#valueand#default_valueproperties
By the end of this tutorial you should know how to populate forms using existing data.
