메시지를 보여주는 PHP 개발 메시지 보드 튜토리얼

다음 코드를 보세요:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>留言板</title>
   <style type="text/css">
        *{margin:0px;padding:0px;}
        body{background:#eee;}
        #bdy{width:414px;height:736px;margin:0 auto;margin-top:20px;
            background:#66CDAA;
        }
        #top{font-family:"隶书";font-size:30px;text-align:center;/*margin-top:18px;*/
            color:#f60;}
        .a{text-decoration:none;color:#fff;float:right;padding-right:15px;}
        .a:hover{color:red;}
        #cont{width:414px;height:736px;margin:0 auto;margin-top:20px;}
        #left{width:350px;height:300px;margin-top:80px;margin-left:15px;/*float:left;*/
            background:#48D1CC;padding-left:5px;}

        #right{width:360px;height:200px;margin-top:20px;background:#48D1CC;
            margin-left:15px;/*float:left;*/}
        h5{text-align:center;margin-top:15px;margin-bottom:20px;}
        #sub{width:120px;height:25px;margin-top:15px;}
        #sub:hover{background:#AFEEEE;}
        .span{font-size:18px;color:red;font-weight:bold;}
        table{width:360px;margin:0 auto;margin-top:15px;border:1px solid #eee;}
        td{text-align:center;}
        #td a{text-decoration:none;color:#eee;}
        #td a:hover{color:red;}
    </style>
</head>
<body>
    <div id="bdy">
        <div id="top">留言板</div>
        <a href="login.php" class="a">登录</a>
        <a href="reg.php" class="a">注册</a>
        <div id="cont">
            <div id="left">
                <h5>写留言</h5>
                <form method="post" action="addmessage.php">
                    标题：<input type="text" placeholder="请输入标题" name="title">
                    </br></br>
                    内容：<textarea cols="40" rows="5" name="content"></textarea>
                    </br></br>
                    <input type="submit" value="添加留言" id="sub">
                </form>
            </div>
            <div id="right"></div>
        </div>
    </div>
</body>
</html>

여기서 <div id="right"></div>

우리는 이 태그에 콘텐츠를 추가한 적이 없습니다. 여기에 메시지가 표시됩니다.

다음 코드를 살펴보겠습니다

<div id="right">
~ ~ ~ ~ TR & gt
& ltd colorpan = "4" id = "td" & gt;
& lt; a href = "" "& gt; 홈 & lt;/a & gt;
& lt; a href =" "" "" "" /a>
~
< ;/table>
</div>

테이블을 사용하여 이제 표시 내용을 작성하겠습니다

파일 헤드에 php 태그를 추가하세요

코드는 다음과 같습니다.

<?php
    session_start();
    require_once('conn.php');//链接数据库

    //分页
    $page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收页码
    $page=!empty($page) ? $page :1;
    
    $table_name="mess";//查取表名设置
    $perpage=5;//每页显示的数据个数

    //最大页数和总记录数
    $total_sql="select count(*) from $table_name";
    $total_result =mysql_query($total_sql);
    $total_row=mysql_fetch_row($total_result);
    $total = $total_row[0];//获取最大页码数
    $total_page = ceil($total/$perpage);//向上整数
    //临界点
    $page=$page>$total_page ? $total_page:$page;//当下一页数大于最大页数时的情况
    //分页设置初始化
    $start=($page-1)*$perpage;

    //展示留言
    $sql1 = "select * from mess order by id desc limit $start,$perpage";
    $res = mysql_query($sql1);
    //$row=mysql_fetch_array($res);
    
?>

그러면 html 페이지 PHP 코드도 추가하세요:

<div id="bdy">
                                                                       ;
                                                                                                     '이름'];?>안녕하세요! </span>
                                                                              ref="reg .php" class="a">등록> lt;/a>
                                                               ">
<h5>메시지 쓰기</h5>
> 제목">
                             /br> ;???? ;
           <div id="right">
                   <tablecellspacing="0" cellpadding="0" border="1">
                       <tr>
                          <번째> ID
                           < ;th>标题
                           内容
                           内容
th>
                       </tr>
                       <?php
                           while($row = mysql_fetch_array ($res)){
                       ?>
                       <tr>
                           <td><?php echo $row[' id'];?></td>
                           <td><?php echo $row['title'];?></td>
                           <td><?php echo $row['content'];?></td>
                          < ;td>< ?php echo $_SESSION['name'];?></td>
                       </tr>🎜                       <?php
                           }
                       ?>
                       <tr>
                          <td colspan="4" id="td">
                               <a href="<?php echo "$_SERVER[PHP_SELF]? page=1"?>">首页</a>
                                  <a href="<?php echo "$_SERVER[PHP_SELF]?page=".($page-1)?>"> ;上一页</a>
                               <a href="<?php echo "$_SERVER[PHP_SELF]?page=".($page+1)?>">下一页</ a>
                               <a href="<?php echo "$_SERVER[PHP_SELF]?page={$total_page}"?>">末页</a> ㅋㅋㅋ       </div>
       </div>

하면是完整代码：

<?php
    session_start();
    require_once('conn.php');//链接数据库

    //分页
    $page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收页码
    $page=!empty($page) ? $page :1;
    
    $table_name="mess";//查取表名设置
    $perpage=5;//每页显示的数据个数

    //最大页数和总记录数
    $total_sql="select count(*) from $table_name";
    $total_result =mysql_query($total_sql);
    $total_row=mysql_fetch_row($total_result);
    $total = $total_row[0];//获取最大页码数
    $total_page = ceil($total/$perpage);//向上整数
    //临界点
    $page=$page>$total_page ? $total_page:$page;//当下一页数大于最大页数时的情况
    //分页设置初始化
    $start=($page-1)*$perpage;

    //展示留言
    $sql1 = "select * from mess order by id desc limit $start,$perpage";
    $res = mysql_query($sql1);
    //$row=mysql_fetch_array($res);
