Deletion is very simple, let’s look at the code directly
<?php require_once('conn.php'); $id = $_GET['id']; $sql="delete from about where id='$id'"; $res = mysql_query($sql); if($res){ echo "<script>alert('删除信息成功');location.href='about.php'</script>"; }else{ echo "<script>alert('删除信息失败');location.href='about.php'</script>"; } ?>
Get the id passed by the deletion link and then delete it based on the id
