Question

我正在尝试在我的PHP文件中创建一个“编辑记录”功能，您可以使用单选按钮编辑行。

我的桌子“书”里面有15条记录。它工作得很好但是当我在我的数据库中添加一行时，它会出现故障并显示：

包含不完整数据的表格。
没有按钮。
500服务器错误（很少）。

我是PHP新手，并且自学有关函数和语法。任何帮助将不胜感激：）

这是我的PHP代码：

<?php
include 'config.php';

session_start();

$sql = "SELECT * from book";
$result = mysqli_query($db, $sql);
$count = mysqli_num_rows($result);

if($count == 0){
    $error = "There is no books in the list";

}

<html>
<body>
<form method="post" action="editinfo.php">

    <table border="1" style="width:80%" align="center">
        <tr>
            <th>Edit</th>
            <th>ISBN</th>
            <th>Title of the book</th>
            <th>Cost</th>
            <th>Copies</th>
            <th>Edition</th>
            <th>Publisher</th>
            <th>Copy Year</th>
            <th>Shelf Number</th>
            <th>Subject</th>

        </tr>
        <?php while ($row = mysqli_fetch_array($result)) {

            $ISBN = $row['ISBN'];
            $Title = $row['Title'];
            $Cost = $row['Cost'];
            $Copies = $row['Copies'];
            $Edition = $row['Edition'];
            $Publisher = $row['Publisher'];
            $CopyYr = $row['CopyYr'];
            $Shelf = $row['ShelfNo'];
            $Subject = $row['SubName'];

            ?>
            <tr>
                <td><input name="editradio" type="radio" value="<?php echo $ISBN; ?>" checked></td>
                <td><?php echo $ISBN; ?></td>
                <td><?php echo $Title; ?></td>
                <td><?php echo $Cost; ?></td>
                <td><?php echo $Copies; ?></td>
                <td><?php echo $Edition; ?></td>
                <td><?php echo $Publisher; ?></td>
                <td><?php echo $CopyYr; ?></td>
                <td><?php echo $Shelf; ?></td>
                <td><?php echo $Subject; ?></td>
            </tr>

            <?php
        }
        ?>
    </table>
    <br>
    <table align="center" style="width:20%">
        <tr>
            <th><input type="submit" name="editinfo" value="Edit Selected"></th>

<form action="bookslist.php" method="post">
