我有一个php代码,用于生成购物车页面,该行的每一行都具有:
前三个我在其中分配了一个类和ID。
例如:
这是我的PHP代码,可以更好地理解我要传达的内容:
<?php
$cart = '';
$id = $_GET['id'];
$cartsql = $conn->prepare("SELECT Barcode, Quantity FROM tblCart WHERE ContactID = :id", $cursor);
$cartsql->bindValue(':id', $id);
$cartsql->execute();
$cartcount = $cartsql->rowCount();
if($cartcount > 0){
$cart .= '<section class="section-md bg-default">
<div class="container">
<div class="table-responsive">
<table class="table-cart">
<thead>
<tr>
<th colspan="2">Product</th>
<th>Price</th>
<th>Quantity</th>
<th>Total</th>
</tr>
</thead>
<tbody>';
while($cartrow = $cartsql->fetch()){
$productsql = $conn->prepare("SELECT StockDesc, RetCash FROM tblStocks WHERE Barcode = :id", $cursor);
$productsql->bindValue(':id', $cartrow['Barcode']);
$productsql->execute();
$productrow = $productsql->fetch();
$productimagesql = $conn->prepare("SELECT TOP 1 SliderImage FROM tblSlider WHERE SliderID = :id", $cursor);
$productimagesql->bindValue(':id', $cartrow['Barcode']);
$productimagesql->execute();
$productimagerow = $productimagesql->fetch();
$total_row = ($cartrow['Quantity'] * $productrow['RetCash']);
$cart .= '<tr>
<td class="table-cart-remove-item">
<span class="btn-remove icon icon-sm linear-icon-cross2 icon-gray-4" id="del-'.$cartrow['Barcode'].'"></span>
</td>
<td style="min-width: 330px">

$cart .= ' </tbody>

}
echo $cart;

我的问题是,更改数量后,如何更改物料的总成本和订单的总成本?我正在使用输入类型编号作为数量。
到目前为止,我要做的是获取输入类型数字的类以获取值。如何正确获取数量并根据数量更改物料和订单的成本?
$(document).ready(function() {
$(document).on("change",".inp-quantity",function() {
var quantity = $(this).val();
var id_name = $(this).attr('id');
var split = id_name.split("-");
var id = split[1];
//HERE IS WHERE I SAVE THE QUANTITY OF THE ORDER
$.ajax({
url: "change-single-item-total.php",
method: "POST",
data: {quantity: quantity,id: id},
success: function(data){
},
error: function(data){
console.log(data);
}
});
});
});
