features values - how to pick variable

[SonnyBoyII]

Hi,

 

Im editing classes/product.php file.

How Can I get a value stored in product feature called lets say xyz and value name abc??

 

I can use very easly 'depth' field :

$product['depth']

$product->depth

 

but how can I call a value stored in value "abc" form "xyz" feature?

[SonnyBoyII]

any ideas, guys?

So you are trying to get a specific feature in classes/Product.php? I can only see a function there to get all features. You could use it and then use a loop to find the right feature. For example:

 

$features = self::getFrontFeatures($id_lang);
$featureValue = null;

foreach ($features as $feature)
   if ($feature['name'] == 'xyz')
       $featureValue = $feature['value'];

briliant! So I need to add this funcion to classes/product.php somewhere and I will be able to use $featureValue to play with other functions??

The getFrontFeatures() function should already exist in classes/Product.php. You can put the above code in a function to get a feature value, assuming the $id_lang variable exists. If it doesn't, you will need to add global $cookie; to the top of the function and then use (int)$cookie->id_lang instead of $id_lang.

Thank you so much, but it doesnt work... im trying to override updateQuantity function and I need feature value to do this:

 

return $productObj->addStockMvt(-(int)($product['cart_quantity'])*($featureValue), (int)_STOCK_MOVEMENT_ORDER_REASON_, (int)$product['id_product_attribute'], (int)$id_order, NULL);

 

That is my whole function:

 

public static function updateQuantity($product, $id_order = NULL)
{

global $cookie;

$features = self::getFrontFeatures((int)$cookie->id_lang);
$featureValue = null;
foreach ($features as $feature) {
   if ($feature.name == 'xyz')
    $featureValue = $feature.value;
 }

	if (!is_array($product))
		die (Tools::displayError());

	if (!Configuration::get('PS_STOCK_MANAGEMENT'))
		return true;

	if (Pack::isPack((int)($product['id_product'])))
	{
		$products_pack = Pack::getItems((int)($product['id_product']), (int)(Configuration::get('PS_LANG_DEFAULT')));
		foreach($products_pack AS $product_pack)
		{
			$tab_product_pack['id_product'] = (int)($product_pack->id);
			$tab_product_pack['id_product_attribute'] = self::getDefaultAttribute($tab_product_pack['id_product'], 1);
			$tab_product_pack['cart_quantity'] = (int)($product_pack->pack_quantity * $product['cart_quantity']);
			self::updateQuantity($tab_product_pack);
		}
	}

	$productObj = new Product((int)$product['id_product'], false, (int)Configuration::get('PS_LANG_DEFAULT'));
	return $productObj->addStockMvt(-(int)($product['cart_quantity'])*($featureValue), (int)_STOCK_MOVEMENT_ORDER_REASON_, (int)$product['id_product_attribute'], (int)$id_order, NULL);
}

 

 

I have checked, the code and idea are right. I get what I wanted using $depth field to store integer but I might to need this field in the future. Thats why I decided to use feature field instead.. unfortunately it seems to be tricky ...

[rocky]

Oops, I've correctly a mistake in my code above.

[SonnyBoyII]

Rocky, the loop stil doesnt work properly for some reason ..

 

public static function updateQuantity($product, $id_order = NULL)
{

global $cookie; 
$features = self::getFrontFeatures((int)$cookie->id_lang);
$featureValue = null;

foreach ($features as $feature) {
   if ($feature['name'] == 'xyz')
    $featureValue = $feature['value'];
}

	if (!is_array($product))
		die (Tools::displayError());

	if (!Configuration::get('PS_STOCK_MANAGEMENT'))
		return true;

	if (Pack::isPack((int)($product['id_product'])))
	{
		$products_pack = Pack::getItems((int)($product['id_product']), (int)(Configuration::get('PS_LANG_DEFAULT')));
		foreach($products_pack AS $product_pack)
		{
			$tab_product_pack['id_product'] = (int)($product_pack->id);
			$tab_product_pack['id_product_attribute'] = self::getDefaultAttribute($tab_product_pack['id_product'], 1);
			$tab_product_pack['cart_quantity'] = (int)($product_pack->pack_quantity * $product['cart_quantity']);
			self::updateQuantity($tab_product_pack);
		}
	}

	$productObj = new Product((int)$product['id_product'], false, (int)Configuration::get('PS_LANG_DEFAULT'));
	return $productObj->addStockMvt(-(int)($product['cart_quantity'])*($featureValue), (int)_STOCK_MOVEMENT_ORDER_REASON_, (int)$product['id_product_attribute'], (int)$id_order, NULL);
}

any idea what is wrong, Rocky?

[rocky]

No, I'd have to actually test the code to figure that out, which takes longer. It's bed time for me though, so I'll have to look at it tomorrow.

Try:

 

public static function updateQuantity($product, $id_order = NULL)
{
global $cookie; 

if (!is_array($product))
 die (Tools::displayError());

if (!Configuration::get('PS_STOCK_MANAGEMENT'))
 return true;

if (Pack::isPack((int)($product['id_product'])))
{
 $products_pack = Pack::getItems((int)($product['id_product']), (int)(Configuration::get('PS_LANG_DEFAULT')));
 foreach($products_pack AS $product_pack)
 {
  $tab_product_pack['id_product'] = (int)($product_pack->id);
  $tab_product_pack['id_product_attribute'] = self::getDefaultAttribute($tab_product_pack['id_product'], 1);
  $tab_product_pack['cart_quantity'] = (int)($product_pack->pack_quantity * $product['cart_quantity']);
  self::updateQuantity($tab_product_pack);
 }
}

$productObj = new Product((int)$product['id_product'], false, (int)Configuration::get('PS_LANG_DEFAULT'));       

$features = $productObj->getFrontFeatures((int)$cookie->id_lang);
$featureValue = null;

foreach ($features as $feature)
 if ($feature['name'] == 'xyz')
  $featureValue = $feature['value'];

return $productObj->addStockMvt(-(int)($product['cart_quantity'])*($featureValue), (int)_STOCK_MOVEMENT_ORDER_REASON_, (int)$product['id_product_attribute'], (int)$id_order, NULL);
}

Its working !! Thanks Rocky!

 

Now, I have the same problem with another function from the same class which I trying override... I have tried to do exactly the same.

The modyfication is working if I use $depth field for instance.

 

If I refound a product in "order" section the loop will crash the page.

 

Here is my code:

 

public static function reinjectQuantities(&$orderDetail, $quantity)
{
	global $cookie;
	if (!Validate::isLoadedObject($orderDetail))
		die(Tools::displayError());

	if (Pack::isPack((int)($orderDetail->product_id)))
	{
		$products_pack = Pack::getItems((int)($orderDetail->product_id), (int)(Configuration::get('PS_LANG_DEFAULT')));
		foreach($products_pack AS $product_pack)
			if (!$product_pack->addStockMvt((int)($product_pack->pack_quantity * $quantity), _STOCK_MOVEMENT_ORDER_REASON_, (int)$product_pack->id_product_attribute, (int)$orderDetail->id_order, (int)$cookie->id_employee))
				return false;
	}

	$features = $productObj->getFrontFeatures((int)$cookie->id_lang);
	$featureValue = null;
		foreach ($features as $feature)
	if ($feature['name'] == 'multi')
	$featureValue = $feature['value'];

	$product = new Product((int)$orderDetail->product_id);

	if (!$product->addStockMvt((int)$quantity*($featureValue), _STOCK_MOVEMENT_ORDER_REASON_, (int)$orderDetail->product_attribute_id, (int)$orderDetail->id_order, (int)$cookie->id_employee))
		return false;

	$orderDetail->product_quantity_reinjected += (int)($quantity);
	return true;
}

[rocky]

You're trying to use the $product object before it's created! Try:

 

public static function reinjectQuantities(&$orderDetail, $quantity)
{
global $cookie;
if (!Validate::isLoadedObject($orderDetail))
 die(Tools::displayError());

if (Pack::isPack((int)($orderDetail->product_id)))
{
 $products_pack = Pack::getItems((int)($orderDetail->product_id), (int)(Configuration::get('PS_LANG_DEFAULT')));                         
 foreach($products_pack AS $product_pack)
  if (!$product_pack->addStockMvt((int)($product_pack->pack_quantity * $quantity), _STOCK_MOVEMENT_ORDER_REASON_, (int)$product_pack->id_product_attribute, (int)$orderDetail->id_order, (int)$cookie->id_employee))
   return false;
}

$product = new Product((int)$orderDetail->product_id, (int)$cookie->id_lang);

$features = $product->getFrontFeatures((int)$cookie->id_lang);
$featureValue = null;
foreach ($features as $feature)
if ($feature['name'] == 'multi')
 $featureValue = $feature['value'];

if (!$product->addStockMvt((int)$quantity*($featureValue), _STOCK_MOVEMENT_ORDER_REASON_, (int)$orderDetail->product_attribute_id, (int)$orderDetail->id_order, (int)$cookie->id_employee))
 return false;
$orderDetail->product_quantity_reinjected += (int)($quantity);
return true;
}

THANKS ROCKY!!

 

Thank this, that topic could be solved:

I think a guide about playing with presta variables and doing customisation like this might be a good idea.

Hi guys,

Now, I would like to use feature values in shopping-cart.tpl.

 

This code doesnt work ....

{assign var="features" value=$product.features}
    {foreach from=$features item=feature}
{feature.name}
{/foreach}

[JulianM]

The code above worked for me on product-list.php

[Qberon]

{assign var="features" value=$product.features}

{foreach from=$features item=feature}

{feature.name}

{/foreach}

 

This code works perfect in product.tpl

 

But how can I get features values in

shopping-cart.tpl

shopping-cart-product-line.tpl

blockcart.tpl

blockcart-json.tpl

 

When I try parse features array in this blocks nothing happen.
