如何获取插入表中的行的自动生成的 id?

问题描述

我正在设计酒店预订系统，在插入客户信息后，我必须发回包含在插入客户信息时自动生成的预订 ID 的确认页面.

I am designing Hotel Booking system, where after insertion of the customer information I have to send back conformation page with the booking_id which is auto-generated when customer information is inserted.

我的问题是如何在相同的php代码中插入数据后获取booking id

还请注意，一个人正在插入数据，所以我认为仅返回最后插入的行无法实现请帮我解决这个问题.

please Note also more that one person is Inserting the data so I think It can't be achieve by just returning last inserted rowPlease help me on this.

我的 javascript 是:

My javascript is:

<script>
    $(document).ready(function(){
        $("#register-form").validate({
            rules: {
                userName: "required",
                email: {
                    required: true,
                    email: true
                },
                userContactNumber: "required"
            },
            messages: {
                userName: "Please enter your Name",
                userContactNumber: "Please enter your Mobile number",
                email: "Please enter a valid email address",
            },
            submitHandler: function(form) {

                var uName = $('#userName').val();
                var mailId = $('#email').val();
                var mobNum = $('#userContactNumber').val();

                $.ajax({
                    url:"http://localhost/bookRoom/book.php",
                    type:"POST",
                    dataType:"json",
                    data:{type:"booking", Name:uName, Email:mailId,  Mob_Num:mobNum},
                    ContentType:"application/json",
                    success: function(response){
                        window.location.href = 'BookingConformation.html';
                    },
                    error: function(err){
                        window.location.href = 'error.html';
                    }
                });
                return false; // block regular submit
            }
        });
    });
</script>

我的服务代码book.php

<?php
    header('Access-Control-Allow-Origin: *');//Should work in Cross Domaim ajax Calling request
    mysql_connect("localhost","root","2190");
    mysql_select_db("hotels");

    if(isset($_POST['type']))
    {
        if($_POST['type']=="booking"){
            $name = $_POST ['Name'];
            $mobile = $_POST ['Mob_Num'];
            $mail = $_POST ['Email'];
            $query1 = "insert into customer(userName, userContactNumber, email) values('$name','$mobile','$mail')";
            $query2 = "insert into booking(cust_name, cust_email, cust_mobile) values('$name', '$mail','$mobile')";

            $result1=mysql_query($query1);

            $result2=mysql_query($query2);
            echo json_encode($result1);
        }
    }
    else{
        echo "Invalid format";
    }
?>

推荐答案

U will get it with mysql_insert_id() 插入数据库后.它会自动返回最新的自动增量 ID.更好的一个 - 使用 PDO 或 MySQLI，因为 mysql_insert_id() 已被弃用.

U will get it with mysql_insert_id() after you insert it into the database. it will automatically give you back the latest Auto Increment ID. better one - use PDO or MySQLI because mysql_insert_id() is deprecated.
