추가, 삭제, 수정, 확인하는 연습을 조금 연습해 볼까요
1. 뉴스 페이지 보기----메인 페이지
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>查看新闻</title> </head> <body> <h1>查看新闻</h1> <table width="100%" border="1" cellpadding="0" cellspacing="0"> <tr> <td>id</td> <td>title</td> <td>author</td> <td>source</td> <td>content</td> <td>date</td> <td>update</td> <td>delete</td> </tr> <?php $db=new MySQLi("localhost","root","","mydb"); !mysqli_connect_error() or die("连接失败!"); $sql="select * from news"; $result=$db->query($sql); $arr=$result->fetch_all(); foreach ($arr as $v) { echo "<tr> <td>{$v[0]}</td> <td>{$v[1]}</td> <td>{$v[2]}</td> <td>{$v[3]}</td> <td>{$v[4]}</td> <td>{$v[5]}</td> <td><a href='Update.php?newsid={$v[0]}'>update</a></td> <td><a href='Delete.php?newsid={$v[0]}'>delete</a></td> </tr>"; } ?> </table> <br> <br /> <div class="xw"><a href="xinwen.php">发布新闻</a></div> </body> </html>
2. 뉴스 페이지 게시-----콘텐츠 추가
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>发布新闻</title> <style> .xw { margin-top:10px; margin-left:400px; border:thick; } .a { float:left; } </style> </head> <body> <h1><center>发布新闻</center></h1> <form action="AddChu.php" method="post"> <div class="xw">标题:<input type="text" name="title" style="width:400px"></div> <div class="xw">作者:<input type="text" name="author"></div> <div class="xw">来源:<input type="text" name="source"></div> <div class="xw">内容: <textarea rows="10" cols="80" name="content"></textarea></div> <div class="a"><input type="submit" value="提交" style="margin-left:600px;"></div> <div class="a"><a href="ChaKan.php"><input type="button" value="查看" style="margin-left:6px;"></a></div> </form> </body> </html>
콘텐츠 제출 후 처리:
<?php $newsid=$_POST["newsid"]; $title=$_POST["title"]; $author=$_POST["author"]; $source=$_POST["source"]; $content=$_POST["content"]; $time=date("Y-m-d",time()); $db=new MySQLi("localhost","root","","mydb"); !mysqli_connect_error() or die("联系失败!"); $sql="insert into news values('{$newsid}','{$title}','{$author}','{$source}','{$content}','{$time}')"; $result=$db->query($sql); if($result) { header ("location:xinwen.php"); } else { echo "添加新闻失败!"; }
3. 콘텐츠 삭제
<?php $newsid=$_GET["newsid"]; $db=new MySQLi("localhost","root","","mydb"); !mysqli_connect_error() or die("连接失败!"); $sql="delete from news where newsid='{$newsid}'"; $result=$db->query($sql); if($result) { header ("location:ChaKan.php"); } else { echo "删除数据失败"; } ?>
4. 뉴스 페이지 수정----뉴스 내용을 수정하고 제출하여 시청하세요
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>修改新闻</title> <style> .xw { margin-top:10px; margin-left:400px; border:thick; } .a { float:left; } </style> </head> <body> <h1><center>修改新闻</center></h1> <?php $newsid = $_GET["newsid"]; $db = new MySQLi("localhost","root","","mydb"); $sinfo = "select * from news where newsid='{$newsid}'"; $r = $db->query($sinfo); $arr = $r->fetch_row(); //这个人的所有信息 ?> <form action="UpdateChu.php" method="post"> <div class="xw"><input type="hidden" name="newsid" value="<?php echo $arr[0] ?>"></div> <div class="xw">标题:<input type="text" name="title" style="width:400px" value="<?php echo $arr[1] ?>"></div> <div class="xw">作者:<input type="text" name="author" value="<?php echo $arr[2] ?>"></div> <div class="xw">来源:<input type="text" name="source" value="<?php echo $arr[3] ?>"></div> <div class="xw">内容: <textarea rows="10" cols="80" name="content"><?php echo $arr[4] ?></textarea></div> <div class="a"><input type="submit" value="修改" style="margin-left:600px;"></div> <div class="a"><a href="ChaKan.php"><input type="button" value="查看" style="margin-left:6px;"></a></div> </form> </body> </html>
처리를 위해 수정된 콘텐츠 제출:
<?php $newsid=$_POST["newsid"]; $title=$_POST["title"]; $author=$_POST["author"]; $source=$_POST["source"]; $content=$_POST["content"]; $time=date("Y-m-d",time()); $db=new MySQLi("localhost","root","","mydb"); !mysqli_connect_error() or die("联系失败!"); $sql="update news set title='{$title}',author='{$author}',source='{$source}',content='{$content}',time='{$time}' where newsid='{$newsid}'"; $result=$db->query($sql); if($result) { header ("location:Update.php"); } else { echo "修改数据失败!"; }
