hello,
i've class that is loaded into the controller
models/wizard.php
Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
/**
* Wizard Model for handeling Signup process
*/
class Wizard extends Model
{
public $current_step = '';
public function __construct()
{
parent::Model();
$this->current_step = $this->_current_step();
}
public function steps($step=null)
{
$steps = array(
'0'=>'first',
'1'=>'personal',
'2'=>'account',
'3'=>'validate');
if(is_null($step)){
return $steps[0];
}else{
if(is_numeric($step)){
return $this->steps();
}elseif(is_string($step) && !is_numeric($step)){
$k = array_search($step, $steps);
return $steps[$k];
}
}
}
public function _current_step()
{
if($this->current_step){
return $this->current_step;
}else{
return $this->steps(0);
}
}
public function next_step()
{
$next_step = $this->current_step + 1;
$this->current_step = $this->steps($next_step);
}
public function prev_step()
{
$prev_step = $this->current_step - 1;
$this->current_step = $this->steps($prev_step);
}
public function is_first_step(){
return $this->current_step == $this->steps(0);
}
public function is_last_step(){
$count = count($this->steps());
$last = $count-1;
return $this->current_step == $this->steps($last);
}
}
in controller
Code:
$this->wizard->steps();
prints the steps array
and
Code:
$this->wizard->_current_step();
echos the current_step value
WHY wouldn't
Code:
$this->wizard->current_step;
work ????
