1 form_example_wizard.inc form_example_wizard_submit($form, &$form_state)

Wizard form submit handler.

This function:

  • Saves away $form_state['values']
  • Process all the form values.

And now comes the magic of the wizard, the function that should handle all the inputs from the user on each different step.

This demonstration handler just do a backdrop_set_message() with the information collected on each different step of the wizard.
