我正在尝试在每一行上添加一个删除按钮,以便在按下按钮时可以删除记录。但删除功能不起作用,并显示“删除记录错误”。我不知道问题出在哪里。
请帮帮我。任何帮助将不胜感激。
这是我的代码:
managetimetable.php
<?php
include("include/config.php");
$sql = "SELECT * FROM `time_table`";
$query = mysqli_query($link,$sql) or die(mysqli_error($link));
?>
<table width="70%" cellpadding="5" cellspacing="5">
<tr>
<th><strong>ID</strong></th>
<th><strong>Image</strong></th>
<th></th>
</tr>
<?php while ($row = mysqli_fetch_array($query)) : ?>
<tr>
<td><?php echo $row['t_id']; ?></td>
<td><?php echo $row['t_name']; ?></td>
<td><a href='delete.php?id=".$row['t_id']."'>Delete</a></td>
</tr>
<?php endwhile; ?>
</table>
delete.php
<?php
$id = $_GET['id'];
include("include/config.php");
$sql = "DELETE FROM time_table WHERE t_id = $id";
if (mysqli_query($link, $sql)) {
mysqli_close($link);
header('Location: index.php');
exit;
} else {
echo "Error deleting record";
}
?>
的config.php
<?php $link=mysqli_connect("localhost","root","","course_registration_system"); ?>
我的数据库: Time_table
t_id t_name t_image
8 course_offered_2017.jpg [BLOB - 246.1 KiB]
9 time_table_2017.jpg [BLOB - 446.4 KiB]
答案 0 :(得分:0)
替换此
<td><a href='delete.php?id=".$row['t_id']."'>Delete</a></td>
与
<td><a href='delete.php?id=<?php echo $row["t_id"];?>'>Delete</a></td>
*尝试使用pdo
