Add to cart issues - what's the actual solution?

[Denniz0229]

so... after reading this whole topic and a lot of other stuff via google I still haven't found a solution.

my website is running VM 2.0.18a and joomla 2.5.8 (website: www.novosmoke.nl)

everything worked perfect, until i made some adjustments to some products, by simply adding child products and making card variants for them.
after that i can't add anything to the cart, and also i am getting this error.

Warning: Invalid argument supplied for foreach() in /public/sites/www.novosmoke.nl/plugins/vmcustom/stockable/stockable.php on line 229

pretty weird that it happened after adding some products. also, the problem only appears in firefox.
and since alot of my customers do use firefox its a pretty nasty problem.

any help would be greatly appreciated.

Do you have a link to a product where errors happen? I just tried to add a few of your child products to the cart using Firefox 20 and all of them were placed into the cart correcty without any errors showing up.

update : It seems to be cause by the quickcart extension, I'll keep you posted

Which JS file does the add to cart button use ?

[Milbo]

atm jquery1.6, but we have now a version running up to jquery1.10

btw I read in another thread this solution, maybe it helps also here

For me it was the same problem: add to cart button fancybox did not work.
tried my page with http://www.hermex.hu, then tried http://hermex.hu
One of them was working well with the add to cart popup, other didn't.

It turned out that in configuration php it was a setting for live site either one link with www or without it.

I just cleared out that setting in configuration.php like this:
public $live_site = '';

And now both way of domain name works correctly.

Can someone check and tell me if the add to cart button works on IE8 and IE9 for this website please? http://forfarfurnitureuk.co.uk/index.php/bedroom-furniture/view/productdetails/virtuemart_product_id/10/virtuemart_category_id/23

I don't want to waste time with virtuemart if I can't get the cart to work on IE

I have it working on Firefox and Chrome. To get it to work on FireFox I had to install JQuery Easy Plugin. With it set to JQuery enabled version 1.4 and subversion 4 (1.4.1).

I am using Joomla! 2.5.17 and Virtuemart 2.0.26d

You have a wrong impression.

The add to cart button works completly normal. The thread is now almost a year old and within this year only 2 people posted that they have a problem with it.

One time

Which JS file does the add to cart button use ?

in your case it will be similar, somehow connected to your template. We cannot prevent that a bad template destroys the features of VM. You may read in our template FAQ http://forum.virtuemart.net/index.php?board=137.0

I will unsticky this post now, because the thread was active almost a year ago and within this year only 2 people posted that they have a problem with it.

As this is something that happens only "sometimes" on your site it must be something "on" your site

If it was a VM bug it would have been reported / noticed 100's of times

On yours I notice there is constant posting from Yandex
you also have google & counterrambling - what ever this is  - but at least unobstrusive Gets

as addto cart is Ajax posts etc maybe this amount of traffic is interfering?

try for a period of time with this traffic hogging switched off?  - just an idea..

Thank you for idea

try for a period of time with this traffic hogging switched off?  - just an idea..

I tried. I deleted them all (Yandex, Google and Rambler counter). Mistake was repeated again, it was still there. It's something else makes all priceses of a products in cart having the cost of a product which I was trying to add the last. But what is it?.. I've noticed that it usually happens when you trying to add something into a cart right after the loading some page with a products. May be some scripts have not enough time to be loaded from a server to make adding operation correct. In other words may be some scripts which influence the cart cann't be downloaded in time. What do you think?
It seems that in a holidays no such mistakes can be detected. May be it depends on hosting capacity. Here is the site

[borro]

After upgrade to VM 2.6.2 the problem of the same costs of all products in a cart has gone. But still sometimes the click on add-to-cart button right after a new category is opened redirects to a cart view. I can't find an multiple jquery loading at site. Please confirm or deny my vision by checking one typical page. So what could be the reason of such rare redirections?
