Delete message
## Create the file del.php
<?php include 'conn.php'; $id = $_GET['id']; $query="delete from message where id=".$id; mysql_query($query); ?> //引入conn文件，使用get方式获取id，使用sql语句来删除id <?php //页面跳转，实现方式为javascript $url = "list.php"; echo "<script>"; echo "window.location.href='$url'"; echo "</script>"; ?> //使用js页面跳转回list查看文件的页面
Key points of this chapter:
- Use the $_GET method to obtain the ID value passed by the address for operation.
- Briefly understand the jump of JS
