Ajax无法正常工作onclick在购物车中

Question

我正在使用免费下载的“ Ustora”模板（电子商务的html主题）。 同样，我正在使用单一产品页面中的“添加到购物车”按钮。 单击后，它应该启动一个ajax函数，它将产品数据插入数据库中我的购物车表中。 但这是行不通的。

我正在与此一起学习使电子商务网站。 请最早提供帮助的是我的以下代码。

单产品-page.php

             <?php 
                $row = mysql_fetch_row(mysql_query("SELECT * FROM `products` where pid='".$_GET['proid']."' "));
                echo '<div class="row">
                    <div class="col-sm-6">
                        <div class="product-images">
                            <div class="product-main-img">
                                <img src="'.$row[5].'" alt="'.$row[2].'">
                            </div>

                            <div class="product-gallery">
                                <img src="'.$row[5].'" alt="'.$row[2].'">

我只想在“添加到购物车”按钮上单击并在要将数据插入购物车后启动addtocart（）函数。

提前致谢

Answer 1

我认为问题出在将数据发送到新页面的数据中

function addtocart(pid,name,price,buid)
    {
    alert("addToCart function working");
    var pid = pid;
    var pname = name;
    var pprice = price;
    var pqty = document.getElementById("qty").value; //$(#qty).val();
    var buid = buid;

    //var cstid = $(#).val();
    $.ajax({
            type:"POST",
            url:"http://localhost/phpsales/insert-cart.php",
            data:{pid,pname,pprice,pqty,buid},//here is the problem 
            data:{pid:pid,pname:pname,pprice:pprice,pqty:pqty,buid:build},//this must be like this
            cache:false,
            success:alert("Product Added Successfully")
            //error:function fail(){alert("Some technical error occured dufine product add to cart. Please try after some time.");}
        });
    }

我认为您需要像这样调用addToCard()函数的引号周围加上引号： onclick="addtocart(/''.$row[1].'/',/''.$row[2]./'',/''.$row[3].'/',/''.$buid.'/');"
