Issue with Ubercart 7.x-3.0-rc4

I'm having this problem too.

It seems that in Ubercart 7.x-3.0-rc4 they have removed the hook hook_uc_cart_item() which this module uses to adjust prices. Until it is updated I believe it will not work with Ubercart rc4.

It looks like the hook has been replaced with the cart item controller in : uc_cart/uc_cart.controller.inc

class UcCartItemController extends UcOrderProductController {

public function attachLoad(&$items, $revision_id = FALSE) {
foreach ($items as &$item) {
$product = uc_product_load_variant($item->nid, $item->data);
// Merge in fields from the product.
foreach ($product as $key => $value) {
$item->$key = $value;
}
$item->module = $item->data['module'];
}
parent::attachLoad($items, $revision_id);
}
}

looking at it now in efforts to replace the hook in the uc_custom price module with the appropriate code for the new controller class.

"needs review" is for when there's a patch.

While the solution would be to extend UcCartItemController in uc_custom_price, modifying UcCartItemController with the out-dated uc_custom_price_uc_cart_item adds custom pricing to cart/order item.

public function attachLoad(&$items, $revision_id = FALSE) {
    foreach ($items as &$item) {
      $product = uc_product_load_variant($item->nid, $item->data);
      // Merge in fields from the product.
      $code = isset($product->custom_code) ? $product->custom_code : '';
      $code = str_replace('$item->price =','$product->display_price = $product->price =',$code);
      if (!empty($code)) {
        $eval_code = token_replace($code, array('product' => $product, 'uc_cart_item' => $item));
        eval($eval_code);
      }
      foreach ($product as $key => $value) {
        $item->$key = $value;
      }
      $item->module = $item->data['module'];
    }
    parent::attachLoad($items, $revision_id);
  }

I have tried placing this code under the uc_custom_price_uc_cart_item function in the uc custom price module, however it causes my entire site to not load.

Can anyone offer some help on this?

Thanks in advance.

*EDIT*

Solved by placing the code snippet under the file located in uc_cart, my mistake!

I've modiffied uc_cart.controller.inc under uc_cart with the hacky
public function attachLoad(&$items, $revision_id = FALSE)
Still nothing happens for me.
I set $item->price = 0; to test but all prices get added as usual to the total amount of cart.

I can use some support with this.

Dang. Why change the API for pricing now, with all new activity going on in Commerce?

Adding the code from #8 to uc_custom_price.module does fix this for me.

Oh, with one major caveat -- in my case I'm grabbing a price from a textfield attribute. You would think you could do this with a rule, but no.

Using uc_custom_price, attribute data is still stored in $item->data. However, when viewing the node, $item->data is a serialized array with stuff you don't need -- it only becomes an array when added to a cart.

So the upshot of this is you need to detect the type before setting price:

$item->price = is_array($item->data) ? $item->data['attributes'][8] : 0;

When we are using the costum price fields, the attribute more price doesn't display and these more prices aren't added.

We are using this rule with a custom discount field:

$item->price = floor((float)$item->list_price - (float)$item->list_price*(float)$item->field_disount_percentage['und'][0]['value']/100 + $item->price);

When using the standard rule:
$item->price = $item->price;
The attribute more price are ok!

Any idea how comes?

Thanks so much r_smylski for a quick solution. Sure looking forward to some more docs to bring us up to speed.

Probably #1823112: Ubercart 3.2 Fix is duplicate, but first comment has the patch which could fix this problem. I'll put status as dublicate.
