资源 id #6 错误，不知道如何解决

Question

在我的网站上提交脚本时，我不断收到“资源 id #6”错误。我使用的代码与我用于注册网站的代码类型相同，并且可以正常工作，但此脚本根本不起作用。我的代码所做的是向数据库发送带有字段的预订请求。我不断收到 Resource id#6 error ，我用谷歌搜索了那是什么，但我似乎无法弄清楚出了什么问题。我是 php 的初学者，所以任何关于寻找什么以避免资源 id #6 错误的提示都会有很大帮助

<?php
//$pattern="/^.+@.+/.com/";

//error_reporting(0);

if(isset($_POST["submit"])){
    $Name_of_Person = $_POST['Name_of_Person'];
    $Name_of_Group = $_POST['Name_of_Group'];
    $room = $_POST['room'];
    $How_Many_People = $_POST['How_Many_People'];
    $Date_of_Booking = $_POST['Date_of_Booking'];
    $End_time = $_POST['End_time'];
    $Purpose = $_POST['Purpose'];
    $Contact_Number = $_POST['Contact_Number'];
    $Contact_Email = $_POST['Contact_Email'];
    $Alcohol = $_POST['Alcohol'];
    $Security = $_POST['Security'];
    $Projector = $_POST['Projector'];
    $Extra_Chairs = $_POST['Extra_Chairs'];
    $Extra_Info = $_POST['Extra_Info'];
    $Activated = '0';

    $con = mysql_connect('localhost','root','test123') or die("couldn't connect");
    mysql_select_db('bookerdb') or die("couldn't connect to DB");


        //if(filter_var($email, FILTER_VALIDATE_EMAIL)){//(preg_match($pattern, $_POST['Contact_Email'])){

            $numrows = mysql_num_rows($query);
            echo $query;
            if($numrows==0){
                $sql="INSERT INTO `booking_table` (Name_of_Person,Name_of_Group,room,How_Many_People,Date_of_Booking,End_time,Purpose,Contact_Number,Contact_Email,Alcohol,Security,Projector,Extra_Chairs,Extra_Info, Activated) VALUES ('$Name_of_Person','$Name_of_Group','$room','$How_Many_People','$Date_of_Booking','$End_time','$Purpose','$Contact_Number','$Alcohol','$Security','$Projector','$Extra_Chairs','$Extra_Info',$Activated)";

Answer 1

您的第二个 SQL 查询出错。您尝试将 14 个值插入 15 列（在您忘记 $Contact_Email 的值中）。

$sql="INSERT INTO `booking_table` (Name_of_Person,Name_of_Group,room,How_Many_People,Date_of_Booking,End_time,Purpose,Contact_Number,Contact_Email,Alcohol,Security,Projector,Extra_Chairs,Extra_Info, Activated) VALUES ('$Name_of_Person','$Name_of_Group','$room','$How_Many_People','$Date_of_Booking','$End_time','$Purpose','$Contact_Number','$Contact_Email','$Alcohol','$Security','$Projector','$Extra_Chairs','$Extra_Info',$Activated)";

从您的代码第 30 行删除 echo $query。

$query 中的不是查询，而是 mysql 结果对象。你不能用这种方式处理它，你不能回应它。
