Checkout Loop

-- url of the page with the problem -- : www.exo-l.com/shop2/accessoires (add anything to cart and go to checkout)
-- HikaShop version -- : 1.6
-- Joomla version -- : 2.5
-- PHP version -- : 5.13
-- Browser(s) name and version -- : Firefox 23
-- Error-message(debug-mod must be tuned on) -- : no errors.

It seems that hikashop decided to loop once the user is in checkout. I have NO idea what happened. I don't remember me fiddling around with this part of the application but this is the problem.

You can go to exo-l.com/shop2/accessoires, add anything to the cart and then proceed to checkout. It will then stay stuck in checkout.
if you append /step-1 and so on to the url it does work

login if necessary:

thanks!

Ok, And can you :
- Set the "Checkout workflow" option to NO
- Show me how your "Advanced checkout workflow edition" option is set now ?

Ok so can you download the last Hikashop version through our website, install it, and test it again ?

That is not an option. We are already running too many custom plugins and what not. I could probably fix it, but I don't know the complete inner workings of hikashop (1.6 is kind of a mess).

However I have isolated it to the cart.php in the checkout folder. I'll update once i find out more

I'm wondering the exact same. I looked narrowed it down to the quantity field in the cart.php file

any idea what could be going wrong? Is there some sort of validation taking place when the "next" button is clicked?

To be more specific its this line:

<input id="hikashop_checkout_quantity_<?php echo $row->cart_product_id; ?>" type="text" name="item[<?php echo $row->cart_product_id; ?>]" class="hikashop_product_quantity_field" value="<?php echo $row->cart_product_quantity; ?>" onchange="var qty_field = document.getElementById('hikashop_checkout_quantity_<?php echo $row->cart_product_id; ?>'); if (qty_field){<?php echo $input; ?>}" />

I'm so frikkin' stupid.

I created a plugin which does some redirecting according to the "step" var.. that var is also used in the checkout process! DOH!

Problem solved!
