Howdy,

I searched the Knop archive for help, but came up empty with "step", "next" and "sequence".

I would like to have a sequence of forms that progress through ordered steps, sort of like a survey. The steps must be performed in order. A user may resume where they left off. Each step has some validation logic. How would I implement this using Knop?

Handling the failure is no problem: just reload the form. But for the success, I'm trying to figure out the best way to load the next Knop form in the sequence.

First, I assume that the application logic should go into the action file, correct?

If so, then here is some sample code I pulled from the Knop demo files.

_action/act_advanced_edit.inc
-----------------------------

if($f -> isvalid); // edited for brevity
// add record
// update session variable
// uhh.... magic? use an include or redirect_url?
/if;

if: (!($f -> isvalid) || $f -> error_code)
&& ($f -> getbutton == 'add' || $f -> getbutton == 'save');
// remain on the same path to show form again
$nav -> (setlocation: ($nav -> actionpath));
// show error message
$message -> (insert: ($f -> error_msg) + ' ' + ($f -> error_code));
/if;

If I understand that correctly, then the value of the -formaction parameter in the knop form object in the config file determines what is the next page in the sequence:

_config/cfg_advanced_edit.inc
-----------------------------
var: 'f'=(knop_form:
-formaction=($nav -> (url: 'advanced')), // action attribute for the html form
-method='post',
-database=$d,
-actionpath='advanced/edit', // framework action path

Is -formaction the "magic" that tells Knop what to load next?
