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
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); ?> <!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> <?php if(!empty($_SESSION['name'])){ ?> <span class="span">尊敬的用户:<?php echo $_SESSION['name'];?>,您好!</span> <?php }else{ ?> <a href="login.php" class="a">登录</a> <a href="reg.php" class="a">注册</a> <?php } ?> <div id="cont"> <div id="left"> <h5>写留言</h5> <form method="post" action="addmessage.php"> 标题:<input type="text" placeholder="请输入标题" name="title"> </br></br> 内容:<textarea cols="40" rows="5" name="content"></textarea> </br></br> <input type="submit" value="添加留言" id="sub"> </form> </div> <div id="right"> <table cellspacing="0" cellpadding="0" border="1"> <tr> <th>ID</th> <th>标题</th> <th>内容</th> <th>留言者</th> </tr> <?php while($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> </td> </tr> </table> </div> </div> </div> </body> </html>
