How to trigger add $10 from radio selection?part2

So i now have a custom field name numberchoice which is a radio selection with the values of keepnumber or newnumber. i want something like this to happpen based on the selection. what can i do to the code below to get what i am looking for.


$already = false;
foreach($this->rows as $i => $row){
if($row->product_code =='Transfer_Number_Fee') $already = true;
}
if($this->order->numberchoice){
if(!$already){
$app =& JFactory::getApplication();
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=1&add=0&return='.urlencode(base64_encode(hikashop::currentUrl()))));
}
}else{
if($already){
$app =& JFactory::getApplication();
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=0&add=1&return='.urlencode(base64_encode(hikashop::currentUrl()))));
}
}

$already = false;
foreach($this->rows as $i => $row){
if($row->product_code =='Transfer_Number_Fee') $already = true;
}
if($this->order->numberchoice=='keepnumber'){
if(!$already){
$app =& JFactory::getApplication();
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=1&add=0&return='.urlencode(base64_encode(hikashop::currentUrl()))));
}
}else{
if($this->order->numberchoice=='newnumber'){
$app =& JFactory::getApplication();
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=0&add=1&return='.urlencode(base64_encode(hikashop::currentUrl()))));
}
}
This is what i have now. it's not doing anything.

well i don't want to mess up the flow of the checkout. this is what it is now cart,login_address_terms,fields,shipping_payment,confirm_address_cart_status,end

your saying to change it to
cart_fields,login_address_terms,shipping_payment,confirm_address_cart_status,end

i don't want the fields to be under the cart. i would like them to be as they are now. what can i do to the code above to make it work like that.

i think that might work since i got the cart view before the end for review. i will be using authorize.net as SIM when will the payment be processed in the checkout i assume at the step end? so that this gets added to the charge at the review step.

landing on the cart i get this.
Fatal error: Call to undefined function hikashop_get() in /home/iqcellul/public_html/templates/ja_anion/html/com_hikashop/checkout/cart.php on line 234


This is the whole code right now


$app =& JFactory::getApplication();
$order = $app->getUserState( HIKASHOP_COMPONENT.'.checkout_fields',null);
$fieldsClass = hikashop_get('class.field');
$this->order = $fieldsClass->getFields('frontcomp',$order,'order');

$already = false;
foreach($this->rows as $i => $row){
if($row->product_code =='Transfer_Number_Fee') $already = true;
}
if($this->order->numberchoice=='keepnumber'){
if(!$already){
$app =& JFactory::getApplication();
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=1&add=0&return='.urlencode(base64_encode(hikashop::currentUrl()))));
}
}else{
if($this->order->numberchoice=='newnumber'){
$app =& JFactory::getApplication();
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=0&add=1&return='.urlencode(base64_encode(hikashop::currentUrl()))));
}
}

is that change across for all the code? will hikashop::completeLink be hikashop_completeLink in the new version?

this is what i have now to try to accomplish a product being added to the cart if a radio selection is selected from the order fields.

$app =& JFactory::getApplication();
$order = $app->getUserState( HIKASHOP_COMPONENT.'.checkout_fields',null);
$fieldsClass = hikashop::get('class.field');
$this->order = $fieldsClass->getFields('frontcomp',$order,'order');

$already = false;
foreach($this->rows as $i => $row){
if($row->product_code =='Transfer_Number_Fee') $already = true;
}
if($this->order->numberchoice=='keepnumber'){
if(!$already){
$app =& JFactory::getApplication();
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=1&add=0&return='.urlencode(base64_encode(hikashop::currentUrl())),false,true));
}
}else{
if($this->order->numberchoice=='newnumber'){
$app =& JFactory::getApplication();
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=0&add=1&return='.urlencode(base64_encode(hikashop::currentUrl())),false,true));
}
}

i tried it with and without the false,true

So it's down to the $app =& JFactory::getApplication();
$order = $app->getUserState( HIKASHOP_COMPONENT.'.checkout_fields',null);
$fieldsClass = hikashop::get('class.field');
$this->order = $fieldsClass->getFields('frontcomp',$order,'order');

cause i used firephp to echo the value of $this->order->numberchoice and in the cart view i get null , but in the fields view i get the correct value. so it's something to do with the code above and bring in the data from the order table.

here i got it working like this

$order = $app->getUserState(HIKASHOP_COMPONENT.'.checkout_fields',null);
$fieldsClass = hikashop::get('class.field');
$this->order = $fieldsClass->getFields('frontcomp',$order,'order');
$already = false;
$clean = false;  
foreach($this->rows as $i => $row){   
 if($row->product_code =='Transfer_Number_Fee') $already = true;
}
  
if(!$already && $plan){
  if($order->numberchoice=='keepnumber'){
  $app =& JFactory::getApplication();   
  $app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=1&add=0&return='.urlencode(base64_encode(hikashop::currentUrl())),false,true));   
  }
}
  elseif($order->numberchoice=='newnumber'){
   if($already){
   $app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=0&add=0&return='.urlencode(base64_encode(hikashop::currentUrl())),false,true));
  }
}
   elseif($order->numberchoice=='keepnumber'){
   if($already && !$plan){
  
  if(!$clean){
  $clean = true;
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=0&add=0&return='.urlencode(base64_encode(hikashop::currentUrl())),false,true));
 }
}
  }else{}

$order = $app->getUserState( HIKASHOP_COMPONENT.'.checkout_fields',null);
$fieldsClass = hikashop::get('class.field');
$this->order = $fieldsClass->getFields('frontcomp',$order,'order')

That worked. The issue now is on the payment view when you click next, which is suppose to go the the review page where it will where the cart view is again with the updated totals. it takes me back to step one of the cart.

$order = $app->getUserState(HIKASHOP_COMPONENT.'.checkout_fields',null);
$already = false;
$clean = false;  
foreach($this->rows as $i => $row){   
 if($row->product_code =='Transfer_Number_Fee') $already = true;
}
  
if(!$already && $plan){
  if($order->numberchoice=='keepnumber'){
  $app =& JFactory::getApplication();   
  $app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=1&add=0&return='.urlencode(base64_encode(hikashop::currentUrl())),false,true));   
  }
}
  elseif($order->numberchoice=='newnumber'){
   if($already){
   $app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=0&add=0&return='.urlencode(base64_encode(hikashop::currentUrl())),false,true));
  }
}
   elseif($order->numberchoice=='keepnumber'){
   if($already && !$plan){
  
  if(!$clean){
  $clean = true;
$app->redirect(hikashop::completeLink('product&task=updatecart&product_id=9&quantity=0&add=0&return='.urlencode(base64_encode(hikashop::currentUrl())),false,true));
 }
}
  }else{}
