i'm dealing with a problem, I need to change the carrier if the cart amount of product with certain tags is > 500 , so , I'm hooking actionCartSave and checking the amount , but , when I do $cart->id_carrier=(int)$carrier_id; $cart->update(); The ajax stops responding and the request remains in pending... like in a loop, then i need to reload the page to see if a product has been added to the cart, but if i remove the $cart->update() the ajax request is successful but , the carrier does not get updated. How can i solve this?

Hi there, The section "Estimate the Cost of Shipping & Taxes" acts totally irrational. The value of "Total" in the" Shopping-Cart Summary" page is not updated according to the shipping rate of selected delivery service from the "Carrier List" after pressing the "Update Cart" button. It just adds the shipping rate of the Default service to the value of "Total Products" (btw. only after pressing the Refresh / Reload browser's button) and stays this way regardless of the selected alternative delivery service. Please see slides in the attachment. Please help or point out at the main files affecting this calculation. Thank you, Alex

While giving some final touches to my store i've observed that when A customer buys a product and moves to Checkout At Cart Summary Step One though the results are accurate for Total(excl. Tax) and Total fields against Default Carrier (As can be seen in Image 1 attached) But if i Change the Carrier and click the Update Cart button the results for Total(excl. Tax) doesn't show any change While Total field shows a result that should be for Total(excl. Tax) (Please see the attached Image 2) Any idea, What should I do to make these two fields [Total(excl. Tax) and Total] to display accurate results.

How do I get help in creating my own custom payment module?I have tried searching for answers the entire web but I am not receiving help from anywhere...Please help

Hi. I need some help please with manual shipping for PrestaShop v1.4.8.2. I'm not using any shipping modules; it'll be all manual. I've tried adding the shipping by price, but that didn't work. So, I tried adding it by weight, but am running into the same problem. I've checked and double-checked my settings, and don't believe I've missed anything. It always helps to get another pair of eyes to check just in case. I'm also including a $1 handling fee for shipment. The problem I'm facing is that the shipping doesn't update automatically in the cart even when I increase the weight level. This is true whether or not I'm logged in during purchase. Secondly, instead of automatically applying the shipping option to the correct weight level during checkout, it gives me the option to select a delivery method. This allows shoppers to select delivery methods for the other weight levels, which I definitely don't want. (Please see attached screenshots.) I deleted the USPS shipping options that came with PrestaShop because I'm not using them. I'm not sure if that's the issue. I also added a separate zone for Canada, so they'll have a different rate than U.S. shoppers and other international shoppers. Thank you in advance for your help.

Hello everyone, I don't want to have a dynamic cart and quick-order page. Instead of "+" and "-" buttons, I'd like to have simple "update cart" button. How to disable ajax or force js to reload page on every change of quantity? I'm looking for answer for a long time and I didn't find anything helpful. I'm using Prestashop 1.4.9 and Prestashop_new skin. Thanks for your help
