新闻修改处理页面

修改页面与添加页面相同 思路一致

<?php
$newsid=$_POST["newsid"]; 
$title=$_POST["title"];
$author=$_POST["author"];
$source=$_POST["source"];
$content=$_POST["content"];
$time=$_POST["time"];

$db=new MySQLi("localhost","root","","xinwen");
!mysqli_connect_error() or die("连接失败！");

//where 条件是根据主键进行修改 这里的newsid是主键
$sql="update news set title='{$title}',author='{$author}',source='{$source}',content='{$content}',time='{$time}' where newsid='{$newsid}'";
$r=$db->query($sql);
if($r)
{
	header("location:zhuye.php");
	}
else
{
	echo"修改失败";
	}
