首先写入一个添加新闻的代码：
<body> <h2>发布新闻</h2> <form action="tianjiachuli.php" method="post"> <div>标题：<input type="text" name="biaoti" /></div> <br /> <div>作者：<input type="text" name="zuozhe" /></div> <br /> <div>来源：<input type="text" name="laiyuan" /></div><br /> <div>内容：<textarea cols="30" rows="5" name="neirong"></textarea></div> <input align="middle" type="submit" value="提交" /> </form> <a href="xinwenbiaoge.php"><input type="submit" value="查看" /></a> </body>
然后点击查看后转换到新闻表格的页面
<body> <table width="100%" border="1" cellpadding="0" cellspacing="0"> <tr> <td>newsid</td> <td>title</td> <td>Author</td> <td>source</td> <td>content</td> <td>time</td> <td>delete</td> <td>upadte</td> </tr> <?php $db = new MySQLi("localhost","root","123","newssystem"); $sql = "select * from news"; $result = $db->query($sql); while($attr = $result->fetch_row()) { echo "<tr> <td>$attr[0]</td> <td>$attr[1]</td> <td>$attr[2]</td> <td>$attr[3]</td> <td>$attr[4]</td> <td>$attr[5]</td> <td><a href='xinwenshanchu.php?newsid={$attr[0]}'>删除</a></td> <td><a href='xinwenxiugai.php?newsid={$attr[0]}'>修改</a></td> </tr>" ; } ?> </table> </body>
然后点击修改后转换到修改页面
<body> <h2>新闻修改</h2> <?php $code = $_GET["newsid"]; $db = new MySQLi("localhost","root","123","newssystem"); $sql = "select * from news where newsid='{$code}'"; $result = $db->query($sql); $attr = $result->fetch_row(); ?> <form action="xinwenxiugaichuli.php" method="post"> <div><input type="hidden" name="id" value="<?php echo $code ?>" /></div> <div>标题：<input type="text" name="biaoti" value="<?php echo $attr[1]?>" /></div> <br /> <div>作者：<input type="text" name="zuozhe" value="<?php echo $attr[2] ?>" /></div> <br /> <div>来源：<input type="text" name="laiyuan" value="<?php echo $attr[3] ?>" /></div><br /> <div>内容：<textarea cols="30" rows="5" name="neirong" value="<?php echo $attr[2] ?>" ></textarea></div> <input align="middle" type="submit" value="提交" /> </form> <a href="xinwenbiaoge.php"><input type="submit" value="查看" /></a> </body>
然后制作一个处理修改的代码
<?php $id = $_POST["id"]; $biaoti = $_POST["biaoti"]; $zuozhe = $_POST["zuozhe"]; $laiyuan = $_POST["laiyuan"]; $neirong = $_POST["neirong"]; $db = new MySQLi("localhost","root","123","newssystem"); $sql = "update news set title='{$biaoti}',Author='{$zuozhe}',source='{$laiyuan}',content='{$neirong}' where newsid='{$id}' "; $r = $db->query($sql); echo $sql; if($r) { header("location:xinwenxiugai.php"); } else { echo "修改失败"; } ?>
