来看下 modifynew.php 的页面
<?php require_once('conn.php'); $id = $_GET['id']; $sql = "SELECT * from news where id='$id'"; $res = mysql_query($sql); $row = mysql_fetch_array($res); ?> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>修改新闻资讯</title> <style type="text/css"> .ipt{width:180px;height:30px;border-radius:5px; outline:none;border:1px solid #eee;box-sizing:border-box;padding-left:15px;} .sub{width:50px;height:20px;border:1px solid #eee;background:#eee;color:#ff7575;} </style> </head> <body> <form method="post" action="modifynews.php?id=<?php echo $id;?>"> 标题:<input type="text" name="title" class="ipt" value="<?php echo $row['title'];?>"> </br></br> 内容:<textarea cols="80" rows="10" name="content" class="txt"><?php echo $row['content'];?></textarea></br></br> 类型:<select name="type"> <option value="0">公司公告</option> <option value="1">公司新闻</option> </select></br></br> <input type="submit" value="修改" class="sub"> </form> </body> </html>
表单提交到 modifynews.php 页面,也带有一个 参数 id
我们来看以下modifynews.php这个页面
代码如下:
<?php require_once('conn.php'); $id = $_GET['id']; $title = $_POST['title']; $type = $_POST['type']; $content = $_POST['content']; $newtime = time(); $sql = "UPDATE news SET title='$title',content='$content',type='$type',newtime='$newtime' where id='$id'"; $res = mysql_query($sql); if($res){ echo "<script>alert('修改新闻资讯成功');location.href='news.php'</script>"; }else{ echo "<script>alert('修改新闻资讯失败');history.go(-1);</script>"; } ?>
如上代码 ,我们就已经完成了修改新闻的功能
