Simple PBN

[dm-coding]

This is a feature request, not a bug.

Complex PBN works great with cakephp-wizard but what about simple PBN? If a given input is a certain value I might want to add a single step, for instance. The PBN in cakephp wizard is not terribly efficient for this scenario.

I envision the API could be trivially extended with getNextStep() and setNextStep() methods in the _processStepX() part of the controller - and, conceptually, that may be a simpler way to envisage complex PBN as well.

In any case the following code works for me - you may want to update the wiki to list this as an alternative to the PBN you have designed:

public function wizard($step = null) {
$wizard_data = $this->Wizard->read();

           //e.g. $condition = !empty($wizard_data['stepname']['data_to_branch_on'];

    if($condition)) {
        $first_array = array_splice ($this->wizard_steps_array, 0, $step_number);
        $this->wizard_steps_array = array_merge ($first_array, $additional_steps_array, $this->wizard_steps_array);
    }
    $this->Wizard->steps = $this->wizard_steps_array;

}

All the best,
