我正在用php ajax创建一个简单的库存系统。所有的销售计算都可以很好地完成。将数据添加到数据库后,数据没有添加到数据库中。我在控制台上没有任何错误。到目前为止我尝试的事在下面附上。表格数据小计
<form class="form-horizontal" role="form" id="frmSummery">
<div>
<label>Total</label>
<input type="text" style="color: yellow; background: black; font-size: 30px;" id="total" name="total" placeholder="Total" class="form-control" required>
</div>
<Form>
[Table data所有销售都应添加此表数据,我将发送到sales_add.php页面。我检查了下面写的console.log(JSON.stringify(items));
完整代码。
function add_product_to_array(item, price,qty, tot)
{
var item = [item, price,qty, tot];
items.push(item);
console.log(JSON.stringify(items));
}
我通过Console.log检查的表已成功显示,如下所示
**[["Chocolate",32,"1",32]]
(index):237 [["Chocolate",32,"1",32],["Mango",10,"1",10]]**
我以这种方式**var data = $('#frmSummery').serialize() + "&items=" + JSON.stringify((items))**
发送到sales.add.php页面
function addProject()
{
var data = $('#frmSummery').serialize() + "&items=" + JSON.stringify((items));
$.ajax({
type: "POST",
url: "sales_add.php",
dataType: 'JSON',
data: data,
success: function (data) {
console.log(_data);
alert("Success");
},
error: function (xhr, status, error) {
alert(xhr);
console.log(xhr.responseText);
}
});
}
Sales.php页面我以这种方式接收数据
**$relative_list = $_POST['items'];
$subtotal= $_POST["total"];**
Sales.php页面
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "icepos";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
$relative_list = $_POST['items'];
$stmt = $conn->prepare("INSERT INTO sales(subtotal)VALUES (?)");
$stmt->bind_param("s",$subtotal);
$subtotal= $_POST["total"];
if ($stmt->execute()) {
$last_id = $conn->insert_id;
} else {
}
for($x = 0; $x < count($relative_list); $x++)
{
$stm = $conn->prepare("INSERT INTO sales_product(sales_id,item,price,qty,total)
VALUES (?,?,?,?,?,?)");
$stm->bind_param("iiiii",$last_id,$item,$price,$qty,$total);
$item= $relative_list[$x]['item'];
$price= $relative_list[$x]['price'];
$qty= $relative_list[$x]['qty'];
$total= $relative_list[$x]['tot'];
if ($stm->execute()) {
}
else {
echo $conn->error;
}
$stm->close();
$stmt2->close();
}
$stmt->close();
}
?>
您的bind param
与您的prepare
的总数不符。删除一个?
:
$stm = $conn->prepare("INSERT INTO sales_product(sales_id,item,price,qty,total)
VALUES (?,?,?,?,?)");
