Deleting a message is actually deleting the data in our database
We passed in the id of each piece of data before deleting the link
So in the PHP page Receive the id and then delete the related id to achieve the deletion function
The code is as follows
<?php header("content-type:text/html;charset=utf-8"); $conn=mysqli_connect("localhost","root","root","ressage"); $id=$_GET['id']; if($conn){ $sql="delete from ressage_user where id ='$id' "; $que=mysqli_query($conn,$sql); if($que){ echo"<script>alert('删除成功,返回首页');location.href='ressage.php';</script>"; }else{ echo "<script>alert('删除失败');location='" . $_SERVER['HTTP_REFERER'] . "'</script>"; exit; } }die("数据库连接失败" .mysqli_connect_error()); ?>
