javascript - 如何使用从两个不同的 SQL 表获取信息的 <td> 输入执行查询保存？

标签 javascript php jquery html mysql

我该如何解决这个问题，因为它只将借阅者的 IDNumber 保存在表格上，而当我单击表格上的“问题”时，我需要保存图书以及借阅者信息？太感谢了。

这是我的问题.php

<?php 
    $fBookCode = $_GET['fBookCode'];

    include_once('includes/connection_db.php');
    $sql = " SELECT * FROM tblbooks WHERE fBookCode = '$fBookCode'";
    $result = mysqli_query($con,$sql);
    while($row = mysqli_fetch_assoc($result))
    {
 ?>

这是我的 transactionsaving.php，它只能保存借款人的 IDNumber + 借用的错误日期时间，因为它不断收到其他人未定义索引的错误..

 <?php

$fBookCode = "";
$fTitle = "";
$fAuthor = "";
$fIDNumber = "";
$fLastName = "";
$fFirstName = "";
$fMiddleName = "";
$fDateBorrowed = "";
$fDateReturned = "";
$fPenalty = "";


if(isset($_POST['btnIssue']))
{
    //$fBookCode = $_POST['fBookCode'];
    //$fTitle =  $_POST['fTitle'];
//  $fAuthor = $_POST['fAuthor'];
    $fIDNumber = $_GET['fIDNumber'];
    //$fLastName = $_POST['fLastName'];
    //$fFirstName = $_POST['fFirstName'];
    //$fMiddleName = $_POST['fMiddleName'];
    $fDateBorrowed = date("Y-m-d h:i:sa");
    //$fDateReturned = $_POST['fDateReturned'];
    //$fPenalty = $_POST['fPenalty'];


$localhost = 'localhost';
$username = 'root';
$password = '';
$dbname = 'bctlibrary db';

$con =  mysqli_connect($localhost, $username, $password, $dbname)
        or die("FAILED CONNECTION");


    $sql = "INSERT INTO tbltransactions
    (fBookCode,
    fTitle,
    fAuthor,
    fIDNumber,
    fLastName,
    fFirstName,
    fMiddleName,
    fDateBorrowed,
    fDateReturned,
    fPenalty)
    VALUES
    ('$fBookCode',
    '$fTitle',
    '$fAuthor',
    '$fIDNumber',
    '$fLastName',
    '$fFirstName',
    '$fMiddleName',
    '$fDateBorrowed',
    '$fDateReturned',
    '$fPenalty')";


    $result = mysqli_query($con,$sql)or die ("QUERY ERROR ". mysqli_error($con));



    mysqli_close($con);


}


?>

最佳答案

您的代码中有一个嵌套表单

<form method="POST" action="">
    <form method="POST" action="">

这不是有效的 HTML。我认为你的问题与此有关。查看 this StackOverflow question 的答案寻求解决方法。

希望这有帮助!干杯!
