Question

我已经通过这个Youtube教程：https://www.youtube.com/watch?v=1YbbUS_SxSk&t=609s

..由于某种原因，我的mySQL表中的数据根本不在表中打印，尽管HTML表中的行数似乎正确。连接到MySQL并与相应的表连接似乎工作正常 - 记录只是不在表中打印。

> <html>
    <head>
        <title>Delete Records</title>
    </head>
    <body>
        <table border=1 cellpadding=1 cellspacing=1>
            <tr>
                <th>Image</th>
                <th>Delete</th>
            </tr>
            <?php
                //connect with mysql
                $con = mysqli_connect('localhost', 'root', '');
                if (!$con){
                    echo"Connection not established";
                }
                //select database
                mysqli_select_db($con, 'photos');

                //select query
                $sql = "SELECT * FROM images";
                if(!$sql){
                    echo"Table not selected";
                }

                //execute the query
                $records = mysqli_query($con, $sql);

                while (mysqli_fetch_array($records)){
                    echo "<tr>";
                    echo "<td>".$row['image']."</td>";
                    echo "<td><a href=delete.php?id=".$row['ID'].">Delete</a></td>";
                    echo "</tr>";
                }
            ?>
        </table>
    </body>
</html>

这是表格最终看起来像： HTML Table

表中没有数据！

Answer 1

更改此行

            while (mysqli_fetch_array($records)){

要

            while ($row = mysqli_fetch_array($records)){

Answer 2

简单错误

 while ($row = mysqli_fetch_array($records))

这应该用于允许自由流动的代码

MySQL记录不在HTML表格中显示
