这里建立一个简易的文章发布系统——后台管理系统，功能包括 文章的发表、查看文章列表，其中还提供对文章的删除和修改功能。
首先使用mysql建立数据库 info，在info数据库中建立一张 article 表：
文章发布系统的目录结构如下：
为实现操作数据库的功能，需要做php连接数据库等操作，所以先封装这些操作，当需要操作数据库时，将文件引入即可。
数据库的配置 config.php
<?php //防止乱码 header("Content-type:text/html;charset=utf-8"); define('HOST','127.0.0.1'); define('USERNAME','root'); define('PASSWORD','root');?><?php require_once('config.php'); //文件头部设置 error_reporting(E_ALL &~E_NOTICE &~E_DEPRECATED); //1.连库 if(!($con = mysql_connect(HOST,USERNAME,PASSWORD))) { echo mysql_error(); } //2.选库 if(!mysql_select_db("info")) { echo mysql_error(); } //3.字符集 if(!mysql_query("set names utf8")) { echo mysql_error(); }?>
下面首先实现发布文章的功能，使用到 bootstrap 建立一个简单的页面 article.add.php ，效果如下：
myCss/style.css
body { font-family:'Hiragino Sans GB','Microsoft Yahei',"WenQuanYi Micro Hei",SimSun,Tahoma,Arial,Helvetica,STHeiti; /* background-color: #BDC3C7; */}textarea { resize: none;}.title { padding-left: 30px;}.body-container { /* border-radius: 8px; padding: 20px; box-shadow: 0 0 1px 1px #DDD; */ margin-bottom: 80px;}.copyright { background-color: #BDC3C7; text-align: center; padding: 20px; position: fixed; bottom: 0px; width: 100%;}
article.add.php

article.add.handle.php
<?php require_once('../connect.php'); //把传递过来的信息入库，在入库之前对所有的信息进行校验。 //print_r($_POST); if(!isset($_POST['title']) || empty($_POST['title'])) { echo "<script>alert('标题不能为空'); window.location.href='article.add.php'</script>"; } $title = $_POST['title']; $author = $_POST['author']; $description = $_POST['description']; $content = $_POST['content']; $dateline = time(); $insertsql = "insert into article(title,author,description,content,dateline) values('$title','$author','$description','$content',$dateline)"; //echo $insertsql; if(mysql_query($insertsql)) { echo "<script>alert('发布文章成功'); window.location.href='article.manage.php'</script>"; } else { echo "<script>alert('发布文章失败'); window.location.href='article.manage.php'</script>"; } mysql_close($con);?>article.manage.php 界面如下：
为了处理文章的删除和修改操作，需要建立对应的php处理文件：article.del.handle.php、article.modify.handle.php。同时还有需要文章信息的界面 article.modify.handle.php。
article.manage.php （需要对数据库进行查找，得到所有文章信息）
<?php require_once('../connect.php'); $sql = "select * from article order by dateline desc"; $query = mysql_query($sql); if($query && mysql_num_rows($query)) { while($row = mysql_fetch_assoc($query)) { $data[] = $row; } } else { $data = array(); }?><!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>管理文章</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta name="description" content="文章发布系统——后台管理系统"> <meta name="author" content="DreamBoy"> <link rel="stylesheet" href="../css/bootstrap.min.css"> <link rel="stylesheet" href="../myCss/style.css"></head><body> <div class="container"> <div class="page-header ex-page-header"> <h1 class="title">文章发布系统<small> ——后台管理系统</small></h1> </div> <div class="body-container"> <div class="row"> <div class="col-md-2"> <div class="panel panel-default"> <div class="panel-heading"> <span class="glyphicon glyphicon-th-list" aria-hidden="true"></span> </div> <div class="list-group"> <a href="article.add.php" class="list-group-item">发布文章</a> <a href="article.manage.php" class="list-group-item active">管理文章</a> </div> </div> </div> <div class="col-md-10"> <div class="panel panel-default"> <div class="panel-heading"> <h4>文章管理列表</h4> </div> <div class="panel-body"> <table class="table table-hover"> <tr> <th>编号</th> <th>标题</th> <th>操作</th> </tr> <tbody> <?php if(!empty($data)) { foreach ($data as $value) { ?> <tr> <td><?php echo $value['id'];?></td> <td><?php echo $value['title'];?></td> <td><a href="article.del.handle.php?id=<?php echo $value['id'];?>">删除</a> <a href="article.modify.php?id=<?php echo $value['id'];?>">修改</a> </td> </tr> <?php } } ?> </tbody> </table> </div> </div> </div> </div> </div> </div> </div> <footer class="copyright"> Copyright ©right; 1995-2016, DreamBoy.NET, All Rights Reserved </footer></body></html>
article.del.handle.php
<?php require_once('../connect.php'); $id = intval($_GET['id']); $deletesql = "delete from article where id=$id"; if(mysql_query($deletesql)) { echo "<script>alert('删除文章成功'); window.location.href='article.manage.php'</script>"; } else { echo "<script>alert('删除文章失败'); window.location.href='article.manage.php'</script>"; }?>
点击“修改”时，将传递对应文章的“id”到修改页面 article.modify.php。修改页面接收到文章id后，根据该id查询该文章的信息，将文章的信息显示在文本框中，供管理员修改。
点击id为6的文章进行修改：
跳转修改界面：
article.modify.php
