How can I use cookies on Webform? I'm using Drupal 7 and Webform and I want, remember input texts on next submissions for registered users.

How can I do it?
Try the Webform Field Repeat  module


  The Webform Field Repeat module enables the webform to remember selected field entries from current submission for up to an hour. It uses the $_SESSION to do so. If the session is active, the form will be populated with selected entries from remembered submission when opened again.
