Question

我在ajax中有以下功能：

    function update_row(ID,CODE,NAME,PRICE){
                $.ajax({
                url: "update-record.php",
                data: "ID="+ID,
                date: "CODE="+CODE,
                data: "NAME="+NAME,
                data: "PRICE="+PRICE,
                type: "post",
                success: function(result){
                    $('#prod2_'+ID).hide();
                }
            });         
    }

这应该调用＆＃34; update-record.php＆＃34;这是以下内容：

<?php
include "config.php";
$product_id = $_POST['ID'];
$product_code = $_POST['CODE'];
$product_name = $_POST['NAME'];
$product_price = $_POST['PRICE'];
$sql = mysql_query("UPDATE `products` SET `code`=$product_code,`name`=$product_name,`price`=$product_price WHERE 'id'=$product_id");
echo json_encode('Record deleted');
?>

这是我用来调用ajax函数的按钮：

'<div><input id=prod2_"'.$row['ID'].'" type=button name="click3" onclick="update_row('.$row['ID'].','.$row['code'].','.$row['name'].','.$row['price'].')" value="Hide"></div>';

此按钮应更新数据库记录并隐藏＆＃34;表格＆＃34;我发布数据的地方。不幸的是它什么也没做。

有任何建议如何解决问题？谢谢你的帮助！

Answer 1

更改此

'<div><input id="prod2_'.$row['ID'].'" type="button" name="click3" onclick="update_row(\''.$row['ID'].'\',\''.$row['code'].'\',\''.$row['name'].'\',\''.$row['price'].'\')" hidden="yes"></div>';

并更改此

您需要连接mysql服务器

$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);

并连接到查询

mysql_query($conn,"UPDATE products SET code='$product_code',name='$product_name',price='$product_price' WHERE id='$product_id'");

并更改此

function update_row(ID,CODE,NAME,PRICE){
                var dataString = 'ID='+ ID + '&CODE=' + CODE + '&NAME=' + NAME + '&PRICE=' + PRICE;
                $.ajax({
                url: "rt.php",//Your php page code this is my test code
                data: dataString,
                type: "post",
                success: function(result){
                    $('#prod2_'+ID).hide();
                }
            });         
    }

Answer 2

您的ajax数据对象有误。请试试这个：

function update_row(ID, CODE, NAME, PRICE) {
    $.ajax({
        url: "update-record.php",
        data: "ID=" + ID+"&CODE=" + CODE+"&NAME=" + NAME + "&PRICE=" + PRICE,
        type: "post",
        success: function(result) {
            $('#prod2_' + ID).hide();
        }
    });
}
