Cart is allways empty - Joomla 1.5.26 - VM 2.0.14

[razor7]

Hi, Just installed VM 2.0.14 on a working site because my client need a shopping cart for his site.

VM works just ok, but when adding a prodct to the cart, the JS popup appears without the link to go to checkuot and the cart module says that the cart is empty. I didn't touched anything, just installed VM, installed samle data and created the menu links.

Is anyone having the same issue?

The site is  Joomla 1.5.26 - VM 2.0.14.

Tanks a lot!

Hello,

Using old joomla but never mind

Did you try without template overrides? Do you use any third party cart module? Do you Cache enabled?

Regards

[razor7]

Cache disabled, no overrides at all (just installed VM), no 3rd party cart module, just mod_virtuemart_cart, as seen on attachment...

EDIT: Using rhuk_milkyway template behaves the same

Hello,

Typical js conflict i suppose, also the cart is not working, there are no products there...

First you are running jquery twice, then you are using https (SSL) without a valid SSL this can produce issues. First please remove ssl option and then unload a jquery instance from loading. You could unload vm jquery and load 1.7.x version instead of 1.8.x from where you running (i suppose k2).

Use firebug to examine your site code and styling .. also for checking js conflicts ...

Hi, the jQuery load issue was solved, but I really dont think it is a JS issue, because the popup displays very well, the issue is with the cart. Just sent you a new PM with a link to test. I have changed the template to rhuk_milkyway to avoid any issues with the original template of the site but the problem persists.

So to be short, I can't add products to cart even using a native template with a fresh VM 2.0.14 install.

[razor7]

Well, I think I found the bug in VM 2.0.14. The issue is that JS function cartEffect : function(form) in vmprices.js, serializes the data to request TWICE!, so, in the other end, the variables get this way quantity%5B%5D=1&option=com_virtuemart&view=cart&virtuemart_product_id%5B%5D=6   (this can be viewed clearly using Eclipse PDT and xDebug), so the whole code fails, because the variables are a complete mess.

I had to change the code from this

Code Select Expand


var datas = form.serialize();
$.getJSON(vmSiteurl+'index.php?option=com_virtuemart&nosef=1&view=cart&task=addJS&format=json'+vmLang,encodeURIComponent(datas),


To this (no double encode)

Code Select Expand

var datas = form.serialize();
$.getJSON(vmSiteurl+'index.php?option=com_virtuemart&nosef=1&view=cart&task=addJS&format=json'+vmLang,datas,


Also found that VM determines which message to show in the popup BEFORE the decission has to be made!, so changed the code in controllers/cart.php, function addJS, and added a new language string to show the correct error.

Code Select Expand

$errorMsg = '';
if ($cart->add($virtuemart_product_ids, $errorMsg )) {
        $errorMsg = JText::_('COM_VIRTUEMART_CART_PRODUCT_ADDED');
$this->json->msg = '<a class="continue" href="' . $continue_link . '" >' . JText::_('COM_VIRTUEMART_CONTINUE_SHOPPING') . '</a>';
$this->json->msg .= '<a class="showcart floatright" href="' . JRoute::_("index.php?option=com_virtuemart&view=cart") . '">' . JText::_('COM_VIRTUEMART_CART_SHOW_MODAL') . '</a>';
if ($errorMsg) $this->json->msg .= '<div>'.$errorMsg.'</div>';
$this->json->stat = '1';
} else {
        $errorMsg = JText::_('COM_VIRTUEMART_CART_PRODUCT_NOT_ADDED');
//$this->json->msg = '<p>' . $cart->getError() . '</p>';
$this->json->msg = '<a class="continue" href="' . $continue_link . '" >' . JText::_('COM_VIRTUEMART_CONTINUE_SHOPPING') . '</a>';
$this->json->msg .= '<div>'.$errorMsg.'</div>';
$this->json->stat = '2';
}

New lang string

COM_VIRTUEMART_CART_PRODUCT_NOT_ADDED="Something went wrong when adding the product to the cart. Please notify the webmaster."

Hello,

I cannot agree with the first one using encodeURIComponent is the only way to work with Unicode UTF-8 urls,  if you remove it then may not properly decode how escape encodes upper ASCII or non-ASCII characters such as: âầẩềểễếệ, so you url will not work! May be adding an option if Unicode Aliases on Joomla Configuration is enabled then make use of encodeURIComponent. The variables are not mess is how are converted, also encodeURIComponent allows spaces.

encodeURIComponent used twice in vmprices.js, also when i am using it ... fix my urls to the variables are NOT getting this way quantity%5B%5D=1&option=com_virtuemart&view=cart&virtuemart_product_id%5B%5D=6

Some more: http://www.w3.org/TR/html401/interact/forms.html#form-content-type

I am thinking you still have JS conflicts with jquery libraries.

On the second haven't check it yet

Well, in my case, the variables get too messy. I can't see any enctype in the product forms. MAybe is my server fault, but I don't know why.

Thanks a lot anyway!
