Json 无法将产品添加到购物车错误prestashop AJAX

我的网站在本周初之前一直运行良好，每当客户尝试添加产品时，都会出现此错误

无法将产品添加到购物车

textStatus:'parsererror'

ErrorRown:'SyntaxError:JSON.parse:JSON数据第1行第3列的JSON数据后出现意外的非空白字符'

答复正文：

45b

{ “产品”：[…]0

但是如果我将其替换为www.domain.com.au，AJAX不会抛出任何错误

我这里几乎没有什么猜测，但我没有解决办法； 我能想到的是，我需要删除空白，但我不知道在哪里。我放在我的blockcart.php中的代码导致了它

全球$smarty

$smarty->assign（'customerDefaultGroup'，Customer:：getDefaultGroupId（Context:：getContext（）->Customer->id））

但我试着把这些注释掉，它仍然让我犯错误。 所以现在，我禁用了AJAX，但客户开始抱怨，他们每次添加产品时都会被引导到购物车

我不知道这是否有关联，每次我访问网站时，我的标题上都有随机字符

帮助

按照我的ajax-cart.js添加函数

// add a product in the cart via ajax
    add : function(idProduct, idCombination, addedFromProductPage, callerElement, quantity, whishlist){
        if (addedFromProductPage && !checkCustomizations())
        {
            alert(fieldRequired);
            return ;
        }
        emptyCustomizations();
        //disabled the button when adding to not double add if user double click
        if (addedFromProductPage)
        {
            $('#add_to_cart input').attr('disabled', true).removeClass('exclusive').addClass('exclusive_disabled');
            $('.filled').removeClass('filled');
        }
        else
            $(callerElement).attr('disabled', true);

        if ($('#cart_block_list').hasClass('collapsed'))
            this.expand();
        //send the ajax request to the server
        $.ajax({
            type: 'POST',
            headers: { "cache-control": "no-cache" },
            url: baseUri + '?rand=' + new Date().getTime(),
            async: true,
            cache: false,
            dataType : "json",
            data: 'controller=cart&add=1&ajax=true&qty=' + ((quantity && quantity != null) ? quantity : '1') + '&id_product=' + idProduct + '&token=' + static_token + ( (parseInt(idCombination) && idCombination != null) ? '&ipa=' + parseInt(idCombination): ''),

            success: function(jsonData,textStatus,jqXHR)
            {
                // add appliance to whishlist module
                if (whishlist && !jsonData.errors)
                    WishlistAddProductCart(whishlist[0], idProduct, idCombination, whishlist[1]);

                // add the picture to the cart
                var $element = $(callerElement).parent().parent().find('a.product_image img,a.product_img_link img');
                if (!$element.length)
                    $element = $('#bigpic');
                var $picture = $element.clone();
                var pictureOffsetOriginal = $element.offset();

                if ($picture.size())
                    $picture.css({'position': 'absolute', 'top': pictureOffsetOriginal.top, 'left': pictureOffsetOriginal.left});

                var pictureOffset = $picture.offset();
                if ($('#cart_block')[0] && $('#cart_block').offset().top && $('#cart_block').offset().left)
                    var cartBlockOffset = $('#cart_block').offset();
                else
                    var cartBlockOffset = $('#shopping_cart').offset();

                // Check if the block cart is activated for the animation
                if (cartBlockOffset != undefined && $picture.size())
                {
                    $picture.appendTo('body');
                    $picture.css({ 'position': 'absolute', 'top': $picture.css('top'), 'left': $picture.css('left'), 'z-index': 4242 })
                    .animate({ 'width': $element.attr('width')*0.66, 'height': $element.attr('height')*0.66, 'opacity': 0.2, 'top': cartBlockOffset.top + 30, 'left': cartBlockOffset.left + 15 }, 1000)
                    .fadeOut(100, function() {
                        ajaxCart.updateCartInformation(jsonData, addedFromProductPage);
                    });
                }
                else
                    ajaxCart.updateCartInformation(jsonData, addedFromProductPage);
            },
            error: function(XMLHttpRequest, textStatus, errorThrown)
            {
                document.write("Impossible to add the product to the cart.\n\ntextStatus: '" + textStatus + "'\nerrorThrown: '" + errorThrown + "'\nresponseText:\n" + XMLHttpRequest.responseText);
                //reactive the button when adding has finished
                if (addedFromProductPage)
                    $('#add_to_cart input').removeAttr('disabled').addClass('exclusive').removeClass('exclusive_disabled');
                else
                    $(callerElement).removeAttr('disabled');
            }
        });
    },

我的ajax-cart.js自定义以检查最小数量

var href = $(this).attr('href').split('=');
            if(typeof href[4] === "undefined")
            { qty = href[3];} //array position changed to 3 after URL rewrite enabled.
            else{ qty = href[4];}
