                        echo "<script> alert('Tama ka.'); </script>";
                    }

                    echo "</table>";

                    mysql_close($con);
            ?>

我遇到了问题，因为代码没有输出我期望的内容。它应该从成员数据库中的memberinformation表输出数据。如果此代码中有一些缺少的行或者我有一些错误，请帮助我。

Answer 1

您正在读取值$ row，而数据位于$ array：

while ($array = mysql_fetch_row($result));
...
echo "<td>" . $row['memberid'] . "</td>";

这应该有效：

while ($row = mysql_fetch_row($result)){
...
echo "<td>" . $row['memberid'] . "</td>";
...
}

Answer 2

你混淆了MySQL和MySQLi库。

将mysqli_connect_errno()替换为mysql_errno()以使用MySQL库。（也适用于mysqli_connect_error()）

但是不要使用已弃用的MySQL库（mysql_*函数），这一点非常重要。用MySQLi和PDO替换它。

Answer 3

您有$array = mysql_fetch_row($result)，但在表中您正在打印，例如$ row ['memberid']而不是$array['memberid']。我相信这将是你的问题。

Answer 4

将$ array = mysql_fetch_row（$ result）更改为$ row = mysql_fetch_row（$ result）

Answer 5

首先，停止使用mysql_函数
其次，您正在混合使用API（mysql_和mysqli_）。请改为选择mysqli_*。
第三，它应该是$row = mysql_fetch_row($result)
第四，尽可能使用参数化查询/预备语句
第五，始终打开错误报告

示例：

<?php
error_reporting(E_ALL);
ini_set("display_errors", 1);

$con = new mysqli('localhost', 'root', '', 'memberdb');
$result = mysqli_query($con, 'SELECT * FROM memberinformation');
 if (mysqli_connect_errno()) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
    echo "<script> alert('May Mali Ka.');</script>";
    //you need to exit the script, if there is an error
    exit();
}

$stmt = $con->prepare('INSERT INTO memberinformation VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)');
$stmt->bind_param('ssssssssssss', $memberid,$lastname,$firstname,$birthdate,$gender,$status,$dedicationdate,$acceptancedate,$baptismdate,$mother,$father,$description);
$stmt->execute();

    </tr>
    <?php while($row = $result->fetch_assoc()): ?>
        <tr>
            <td><?php echo $row['lastname']; ?></td>
            <td><?php echo $row['firstname']; ?></td>
            <td><?php echo $row['birthdate']; ?></td>
            <td><?php echo $row['gender']; ?></td>
            <td><?php echo $row['status']; ?></td>
            <td><?php echo $row['dedicationdate']; ?></td>
            <td><?php echo $row['acceptancedate']; ?></td>
            <td><?php echo $row['baptismdate']; ?></td>
            <td><?php echo $row['mother']; ?></td>
            <td><?php echo $row['father']; ?></td>
            <td><?php echo $row['description']; ?></td>
