Error 500 - Add to Cart

[HenriBierman]

Hi All

 

My website is giving an error 500, when add to cart on some items.  But the items is in stock.

 

Here is the Debug Report:

What could this be?

102:		if (is_array($cart_products))
103:			foreach ($cart_products as $cart_product)
104:			{
105:				if ((!isset($this->id_product_attribute) || $cart_product['id_product_attribute'] == $this->id_product_attribute) &&
106:					(isset($this->id_product) && $cart_product['id_product'] == $this->id_product))
107:				{
108:					$qty_to_check = $cart_product['cart_quantity'];
109:
110:					if (Tools::getValue('op', 'up') == 'down')
111:						$qty_to_check -= $this->qty;
112:					else
113:						$qty_to_check += $this->qty;
114:
115:					break;
116:				}
117:			}
118:
119:		if ($this->id_product_attribute)
120:		{
121:			if (!Product::isAvailableWhenOutOfStock($product->out_of_stock) && !Attribute::checkAttributeQty($this->id_product_attribute, $qty_to_check))
122:				$this->errors[] = Tools::displayError('There isn\'t enough product in stock.', !Tools::getValue('ajax'));
123:		}
124:		elseif ($product->hasAttributes())
125:		{
126:			$minimumQuantity = ($product->out_of_stock == 2) ? !Configuration::get('PS_ORDER_OUT_OF_STOCK') : !$product->out_of_stock;
127:			$this->id_product_attribute = Product::getDefaultAttribute($product->id, $minimumQuantity);
128:			if (!$this->id_product_attribute)
129:				Tools::redirectAdmin($this->context->link->getProductLink($product));
130:			elseif (!Product::isAvailableWhenOutOfStock($product->out_of_stock) && !Attribute::checkAttributeQty($this->id_product_attribute, $qty_to_check))
131:				$this->errors[] = Tools::displayError('There isn\'t enough product in stock.', !Tools::getValue('ajax'));

Did you recently update your TB?

Not too recently, the update module did mention there was some changes that it needs to fix about 2 days ago, which I did.

[HenriBierman]

Whats very strange is that it only does this on some products.  I even deleted one listing and recreated it.  But the error persist.

 

[the.rampage.rado]

Because few months back there was a large rework for attributes. I imagine you don't have pending DB changes to do in coreupdater?

[HenriBierman]

At Core Update, all shows updated.  But by Database there is a few open for Apply Fix.  Do you think its safe to Apply them all?

 

[the.rampage.rado]

Screenshot? Most fixes are fine if you had never tweaked manually the DB

[HenriBierman]

 

Here is many.  Was always scared I might break something when I hit apply.

 

[the.rampage.rado]

Make a DB backup before you apply all of those. Most are non-critical (ignore the red label) but few of them might be part of this rework I mentioned.

Each file update to most recent bleeding edge version should be followed by check and update on any available fixes here because otherwise the shop might end up broken.

Thank you, I just applied them all, but it seams like the Error is still there when I add that product.  What I find off is that the older products add to cart 100%, but not this new product.

Can you describe your product setup?

Do you use ASM?

Can you put the settings from here:

The very first image, with error on line 121, is from override, isn't it?

[the.rampage.rado]

 

[HenriBierman]

Here is the product setup.

 

 

[HenriBierman]

Yes, Override is currently active

Here is the link to the actual product,  the other items add to cart without issues.  But this product - Haloop gives the problem.

Rename class Attribute to ProductAttribute as it was renamed in TB for compatibility with php 8.

Thanks. This screenshot provides much more information that your first one. 

We now know the actual error message: Class 'Attribute' not found, and we know that it comes from override. 

The override is referencing Attribute class that does not exists anymore in thirty bees core, because it's reserved name in PHP8. 

You have probably installed some some module recently that added this override, or you have updated your store.

Anyway, the fix is to edit the override file, and change Attribute::checkAttributeQty to ProductAttribute::checkAttributeQty

There might be more usages of Attribute class, you have to replace them all.

[HenriBierman]

Its as if it doesnt see the stock,  when I change it to Allow Orders when out of stock, then add to cart is working.  But when I set it to Deny, then it gives the erorr.  And there is stock.. 

[HenriBierman]

Where can I rename these Attributes?

Open this file:

and edit the highlighted 121 line to datakicks version and it will work as it used to before. 😉
