Your were extending ObjectModel class with a non-existing class (LoyaltyAPICore) - so the override could not be created. You should extend ObjectModel class, like this: It should work fine now. Tested on PS 1.6.1.20.

Hello, SHORT INTRODUCTION I was never satisfied with the native behaviour of "delayed shipping" feature in PS 1.6 - it's very helpful but it just doesn't work properly and I wanted to improve it. I have managed to add JSON support and changed its behaviour a little bit. Previously I have modified the behaviour of AVAILABILITY column (which I also described here) in shopping-cart-product-line.tpl, so it now shows 'STOCK quantity' and 'BACKORDER quantity' (or ON REQUEST in my case, since I'm using module which disables COD payment for orders with BACKORDER products and leaves only pre-payment methods). Now, we have a several cases regarding the "delayed shipping" feature, which we have to investigate: 1) All products in cart have no stock (stock quantity <= 0) in the cart -> delayed shipping not appearing (in native PS it was appearing which was wrong - there is nothing to split here) = works OK -> https://streamable.com/guvfv 2) All products in cart have positive stock (stock quantity > 0) -> delayed shipping appears when the cart quantity exceeds stock quantity - works OK -> https://streamable.com/3v7kh 3) Products in cart have both positive stock (stock quantity > 0) and no stock (stock quantity <= 0). I'm deleting out_of_stock products form the cart - works OK -> https://streamable.com/r3ipf I'm deleting in_stock products form the cart - works OK -> https://streamable.com/j3fdf CODE MODIFICATIONS File: \classes\Cart.php -> I have added 2 functions, which are counting in_stock nad out_of_stock (backorder) products in the cart public function countOOSProducts() { $product_out_of_stock = 0; foreach ($this->getProducts() as $product) { if ((int)$product['quantity_available'] <= 0 && (!$ignore_virtual || !$product['is_virtual'])) { $product_out_of_stock++; } } return $product_out_of_stock; } public function countISProducts() { $product_in_stock = 0; foreach ($this->getProducts() as $product) { if ((int)$product['quantity_available'] > 0 && (!$ignore_virtual || !$product['is_virtual'])) { $product_in_stock++; } } return $product_in_stock; } I have added new variables returned by these functions to summary array() to pass them into front files, so the new array() looks like this: $summary = array( 'delivery' => $delivery, 'delivery_state' => State::getNameById($delivery->id_state), 'invoice' => $invoice, 'invoice_state' => State::getNameById($invoice->id_state), 'formattedAddresses' => $formatted_addresses, 'products' => array_values($products), 'gift_products' => $gift_products, 'discounts' => array_values($cart_rules), 'is_virtual_cart' => (int)$this->isVirtualCart(), // adding 2 new variables 'product_in_stock' => $this->countISProducts();, 'product_out_of_stock' => $this->countOOSProducts();, 'total_discounts' => $total_discounts, 'total_discounts_tax_exc' => $total_discounts_tax_exc, 'total_wrapping' => $this->getOrderTotal(true, Cart::ONLY_WRAPPING), 'total_wrapping_tax_exc' => $this->getOrderTotal(false, Cart::ONLY_WRAPPING), 'total_shipping' => $total_shipping, 'total_shipping_tax_exc' => $total_shipping_tax_exc, 'total_products_wt' => $total_products_wt, 'total_products' => $total_products, 'total_price' => $base_total_tax_inc, 'total_tax' => $total_tax, 'total_price_without_tax' => $base_total_tax_exc, 'is_multi_address_delivery' => $this->isMultiAddressDelivery() || ((int)Tools::getValue('multi-shipping') == 1), 'free_ship' =>!$total_shipping && !count($this->getDeliveryAddressesWithoutCarriers(true, $errors)), 'carrier' => new Carrier($this->id_carrier, $id_lang), ); File: \themes\your_theme\js\cart-summary.js -> I have modified function updateCartSummary(json) a little bit by adding following code: // Definition of variable storing the each line 'backorder quantity' in shopping cart 886: var OosProducts = 0; // Definition of variable storing the total 'backorder quantity' in shopping cart 887: var OosProductsTotal = 0; // Definition of the variable storing 'available_later' text 921: var available_later = product_list[i].available_later; // JSON support for AVAILABILITY column 0991: OosProducts = parseInt(product_list[i].quantity) - parseInt(product_list[i].quantity_available); 0992: if (OosProducts > 0) { 0993: $('#outofstock_availability_' + key_for_blockcart).html(available_later + ' (' + quantity + ': ' + OosProducts + ')'); 0994: $('#outofstock_availability_' + key_for_blockcart).show(); 0995: } 0996: else { 0997: $('#outofstock_availability_' + key_for_blockcart).hide(); 0998: } 0999: nbrProducts += parseInt(product_list[i].quantity); 1000: OosProductsTotal += OosProducts; 1001: } // JSON support for "delayed shipping" block 1004: if (json.product_out_of_stock == 0 && json.product_in_stock > 0) { 1005: if ((OosProducts-OosProductsTotal == 0 && OosProducts > 0) || (OosProducts-OosProductsTotal < 0 && OosProducts >= 0) || (OosProducts-OosProductsTotal < 0 && OosProducts < 0) || (OosProducts-OosProductsTotal > 0 && OosProducts > 0)) { 1006: $('.allow_seperated_package').show(); 1007: $('.allow_seperated_package').css({'color':'white', 'background-color':'orange', 'padding':'10px', 'display':'inline-block'}); 1008: } else { 1009: $('.allow_seperated_package').hide(); 1010: } 1011: } else if(json.product_out_of_stock > 0 && json.product_in_stock == 0) { 1012: $('.allow_seperated_package').hide(); 1013: } else { 1014: $('.allow_seperated_package').show(); 1015: } File: \themes\your_theme\shopping-cart.tpl -> I have modified the native "delayed shipping" code: 638: <p class="allow_seperated_package" {if ($show_option_allow_separate_package && {$product_in_stock} > 0)}style="background: orange;

And basically that's it. Maybe someone finds it helpful in his adventure with PrestaShop. If anyone has any suggestions I would bevery grateful. Best regards, Radoslaw

Hi, I have achieved it in 1.6.1.20 PS instance by following modifications (with autoupdate): File: \classes\Cart.php (but you should use override here) -> added following lines: 3167: $total_weight = $this->getTotalWeight(); 3256: 'total_weight' => $total_weight, File: \themes\yourtheme\js\cart-summary.js -> added following line: 958: $('#total_weight').html(json.total_weight); File: \themes\yourtheme\shopping-cart.tpl -> added following lines in proper place of your template shopping-cart.tpl file: <tr class="cart_total_weight"> <td colspan="{$col_span_subtotal}" class="text-right">{l s='Total weight'}</td> <td colspan="4" class="price"><span id="total_weight">{$cart->getTotalWeight()}</span> {Configuration::get('PS_WEIGHT_UNIT')}</td> </tr>
