Product price editable on checkout

Thanks but it doesn't work, I miss something for sure, this is my code :

<?php
define( '_JEXEC', 1); //  This will allow to access file outside of joomla.
define( 'DS', DIRECTORY_SEPARATOR );
define( 'JPATH_BASE', realpath(dirname(__FILE__) .'/' ) );
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();
$user = JFactory::getUser();
$session =& JFactory::getSession();
$database = JFactory::getDBO();
if(!include_once(rtrim(JPATH_ADMINISTRATOR,DIRECTORY_SEPARATOR).DIRECTORY_SEPARATOR.'components'.DIRECTORY_SEPARATOR.'com_hikashop'.DIRECTORY_SEPARATOR.'helpers'.DIRECTORY_SEPARATOR.'helper.php')) return true;


$app = JFactory::getApplication();
$order_id = $app->getUserState('com_hikashop.order_id');
if (!$order_id) die("Nessun id ordine");


//GET IVA
$query = $database->getQuery(true);
$query->select('tax_rate');
$query->from($database->quoteName('#__hikashop_tax'));
$query->where($database->quoteName('tax_namekey')." = ".$database->quote('IVA'));
$database->setQuery($query);
$iva = $database->loadResult(); 

$orderClass = hikashop_get('class.order');
$orderProductClass = hikashop_get('class.order_product');
$fullorder = $orderClass->loadFullOrder($order_id,false,false);

$input = new JInput;
$post_array = $input->getArray($_GET);
$prodotto = new stdClass();


$prodotto->order_product_id = $post_array[$id];
$prodotto->order_product_quantity = 1;
$prodotto->order_product_price = 100;
$products = array ($prodotto);
$orderProductClass->save($products);

The save function of orderProductClass is to add new order_products, not to update existing ones.
For existing ones, you want to use instead the update function of orderProductClass and in that case, it's the product object that you want to pass to the function.

For the recalculatefullprice function, I don't know what code you're using to call it so I can't say much more.

• I edited end.php with a form to let the user write the new price of every product in order, the form sends this data to a save.php, it passes order_product_price and order_product_id.
• Inside save.php I load joomla and hikashop framework, then with a for I write in a standard class the data passed by the POST, in this way:

  for ($i = 0; $i < count ($fullorder->products); $i++){
  	$id = "orderidprodotto". $i;
  	$prezzo = "prezzo". $i;
  	$prodottoinordine = $orderProductClass->get($post_array[$id]);
  
          $obj = new stdClass();
  	$obj->order_product_id = $post_array[$id];
  	$obj->order_id = $prodottoinordine->order_id;
  	$obj->product_id = $prodottoinordine->product_id;
  	$obj->order_product_quantity = (int) $prodottoinordine->order_product_quantity;
  	$obj->order_product_name = $prodottoinordine->order_product_name;
  	$obj->order_product_code = $prodottoinordine->order_product_code;
  	$obj->order_product_price = (float) $post_array[$prezzo];
  	$obj->order_product_tax = (float) $post_array[$prezzo] * $iva;
  
  	$element[$i]=$obj;
  }

  and put it in an array ($element). $prodottoinordine is an object loaded with the class.order_product ($prodottoinordine = $orderProductClass->get($post_array[$id]))
  
• Now what I need is recalculate all the total and subtotal prices (can recalculatefullprice helps me?) and finally save (update?) my order
  

ok, something works, it needs to update every order_product inside the for, the passed object must have an order_product_id and an order_product_quantity, plus the data to edit, order_product_price and order_product_tax in my case. Hoping this info can helps someone else. EDIT: ok I can directly use the object loaded by order_prodcut class, just modifying price and tax and updating it by the update function (the save function wanted a new object, so I was using a new obj).
Now I need to update the order info, like order_full_price, order_subtotal, order_tax_info, can I use the recalculatefullprice function to automate this action? If yes there is something that I need to know ? Once I recalculate all the total and subtotal, can I use class.order save function? Or there is an update like orderproduct?

You are fantastic and you have a lot of patience , but I have to say it , the documentation is really poor , would be useful more doc about at least the most basic functions .

Thanks, now all seems to work. I just add this code for the order product tax info :

$tasse = unserialize($prodottoinordine->order_product_tax_info);
$tasse[0]->tax_amount = $prodottoinordine->order_product_tax;
$prodottoinordine->order_product_tax_info = serialize($tasse);
