我正在尝试使用模态添加记录。我使用了以下代码，但我的记录没有添加到数据库中..帮助我通过pls

<link rel="stylesheet" type="text/css" href="/Project/Style/bootstrap.css"/>
     <script src="Style/jQuery/jquery-1.11.1.min.js" type="text/javascript"></script>
     </head>
    <body>

    <div id="container">
    <?php
    include('header.php');
    require_once('Connections/conn.php');

    $sql2= "SELECT * from type where cid='1' ";
    $results =mysqli_query($conn,$sql2);


    ?>

    <div id="main">

    // haddling the post for adding record
    $('#add').click(function(){

        var proname = $('#proname').val();
        var pro_type = $('#pro_type').val();
        var qty = $('#qty').val();
        var price = $('#price').val();
        var pdate = $('#pdate').val();

        var datas="proname="+proname+"&pro_type="+pro_type+"&qty="+qty+"&price="+price+"&pdate"+pdate;


    $.ajax({
           type: "POST",
           url: "addpro_exec.php",
           data: datas,
           success:function(data){

        },
         error: function(){

                     }
        });
        });
    </script>

处理发布数据的代码如下 //addpro_exec.php文件

<?php
    require_once('Connections/conn.php');
    if(isset($_POST['add'])){

    $proname=$_POST['proname'];
    $pro_type= $_POST['pro_type'];
    //$typname=$_POST['type_name'];
    $qty=   $_POST['qty'];
    $price= $_POST['price'];
    $pdate= $_POST['pdate'];
    $asdate = \date('F');
        $sql="INSERT into product VALUES('','$proname','','$qty','$price','$pdate','','$pro_type','1') ON DUPLICATE KEY UPDATE qty = qty+$qty";
        $sql2= "INSERT into year_estm VALUES('','$proname','$asdate','$qty','') ON DUPLICATE KEY  update   Production_input=Production_input+$qty ";
    $AddProduction=  mysqli_query($conn, $sql2) or die('Cannot add to production'. mysqli_error($conn));
    $RecAdd= mysqli_query($conn,$sql) or die('Cannot add Product' . mysqli_error());
    if($RecAdd){
        header('location:viewfarm.php');
    }

    }

    else{

    }

    ?>

Answer 1

在javascript中尝试以下行：

var datas="add=1&proname="+proname+"&pro_type="+pro_type+"&qty="+qty+"&price="+price+"&pdate="+pdate;

这应该解决问题。

警告：在插入数据库之前，请务必过滤并正确引用用户输入，以避免SQL注入攻击。使用准备好的陈述来帮助实现这一目标。
