制作一个简单的PHP新闻列表框架
1、首先在Eclipse PHP上建立文件框架;
-----admin 后台文件夹
-----common 类配置文件夹
-----config配置文件(系统配置文件)
------templates (Smarty 配置的HTML文件夹)
------templates_c(Smarty缓存文件夹)

2、添加管理员数据库;
建立一个test数据库,建立一个p_admin表格,在表格上建立一个admin的管理员账号,密码采用md5()编译过后的密码,复制到password中。

3、配置smarty文件;
1.将smarty文件复制到common的文件夹中,实现前台与后台的页面分离;
2.在global.php文件中设置smarty的调用程序;
$smarty = new Smarty(); //调用smarty函数
$smarty ->template_dir =$smarty_template_dir;//配置smarty的模板路径
$smarty ->compile_dir =$smarty_complie_dir;//配置smarty的编译路径
$smarty ->config_dir =$smarty_config_dir;//配置smarty的配置路径
$smarty ->cache_dir =$smarty_cache_dir;//配置smarty的缓存路径
$smarty ->caching =$smarty_caching;//配置smarty的缓存
$smarty ->left_delimiter =$smarty_delimiter[0];//配置smarty的分隔符
$smarty ->right_delimiter=$smarty_delimiter[1];//配置smarty的分隔符
3.在config/config.php文件中配置smarty;
$smarty_template_dir ='./templates/';
$smarty_complie_dir ='./templates_c/';
$smarty_config_dir ='./configs/';
$smarty_cache_dir ='./cache/';
$smarty_caching = FALSE;
$smarty_delimiter =explode("|","{|}");
4.调试smarty是否配置完成;
在index文件上:
1.在template模板文件夹中放置index.html文件夹;
2.在index.php文件夹中配置代码:
$smarty->display("index1.html"); 测试smarty是否配置成功。
4、配置数据库;
1.配置数据库的类;(这里分享一个很经典的php mysql的类)
class mysql {
private $db_host; //数据库主机
private $db_user; //数据库用户名
private $db_pwd; //数据库用户名密码
private $db_database; //数据库名
private $conn; //数据库连接标识;
private $result; //执行query命令的结果资源标识
private $sql; //sql执行语句
private $row; //返回的条目数
private $coding; //数据库编码,GBK,UTF8,gb2312
private $bulletin = true; //是否开启错误记录
private $show_error = true; //测试阶段,显示所有错误,具有安全隐患,默认关闭
private $is_error = false; //发现错误是否立即终止,默认true,建议不启用,因为当有问题时用户什么也看不到是很苦恼的
/*构造函数*/

exit();
}
}
}
$db=new mysql($db_host, $db_user, $db_pwd, $db_database,$conn,$coding);
?>
2.测试数据库是否连接成功:
1.$db = new action($db_host, $db_user, $db_pwd,$db_database,$conn,$coding); //实例化数据库类;
2.代码测试数据库是否连接成功:
$query=$db->queryquery(select*from p_admin);
$row=$db->fetch_array($query);
echo $row[username];
5、编写后台登录界面;
1.配置后台操作控制类action.class.php:
代码如下:(此代码的目的为了后台判断及跳转)
<?php
class action extends MySQL {
/**
* 用户权限判断($uid, $shell, $m_id)
*/
public function Get_user_shell($uid, $shell) {
$query = $this->select('p_admin', '*', '`uid` = \'' . $uid . '\'');
$us = is_array($row = $this->fetch_array($query));
$shell = $us ? $shell == md5($row[username] . $row[password] . "PHP100") : FALSE;
return $shell ? $row : NULL;
} //end shell
public function Get_user_shell_check($uid, $shell, $m_id = 9) {
if ($row=$this->Get_user_shell($uid, $shell)) {
if ($row[m_id] <= $m_id) {
return $row;
} else {
echo "你无权限操作!";
exit ();
} //end m_id
} else {
$this->Get_admin_msg('index.php','请先登陆');
}
} //end shell
//========================================
/**
* 用户登陆超时时间(秒)
*/
public function Get_user_ontime($long = '3600') {
$new_time = mktime();
$onlinetime = $_SESSION[ontime];
echo $new_time - $onlinetime;
if ($new_time - $onlinetime > $long) {
echo "登录超时";
session_destroy();
exit ();
} else {
$_SESSION[ontime] = mktime();
}
}
/**
* 用户登陆
*/
public function Get_user_login($username, $password) {
$username = str_replace(" ", "", $username);
$query = $this->select('p_admin', '*', '`username` = \'' . $username . '\'');
$us = is_array($row = $this->fetch_array($query));
;
$ps = $us ? md5($password) == $row[password] : FALSE;
if ($ps) {
$_SESSION[uid] = $row[uid];
$_SESSION[shell] = md5($row[username] . $row[password] . "PHP100");
$_SESSION[ontime] = mktime();
$this->Get_admin_msg('main.php','登陆成功!');
} else {
$this->Get_admin_msg('index.php','密码或用户错误!');
session_destroy();
}
}
/**
* 用户退出登陆
*/
public function Get_user_out() {
session_destroy();
$this->Get_admin_msg('index.php','退出成功!');
}
/**
* 后台通用信息提示
*/
public function Get_admin_msg($url, $show = '操作已成功!') {
$msg = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<link rel="stylesheet" href="css/common.css" mce_href="css/common.css" type="text/css" />
<meta http-equiv="refresh" content="2; URL=' . $url . '" />
<title>管理区域</title>
</head>
<body>
<div id="man_zone">
<table width="30%" border="1" align="center" cellpadding="3" cellspacing="0" class="table" style="margin-top:100px;" mce_style="margin-top:100px;">
<tr>
<th align="center" style="background:#cef" mce_style="background:#cef">信息提示</th>
</tr>
<tr>
<td>' . $show . '<br />
2秒后返回指定页面!<br />
如果浏览器无法跳转,<a href="' . $url . '" mce_href="' . $url . '">请点击此处</a>。</td>
</tr>
</table>
</div>
</body>
</html>';
echo $msg;
exit ();
}
//========================
} //end class
?>
2.配置后台配置公共文件:admin_global.php,代码如下:
<?php
session_start(); //通过session进行数据传值
include_once '../configs/config.php';
include_once '../common/db.class.php';
include_once 'common/action.class.php';
include_once 'common/page.class.php';
$db= new action($db_host, $db_user, $db_pwd, $db_database, $conn , $coding);//数据库操作类
$uid= $_SESSION[uid];
$shell= $_SESSION[shell];
?>
4.配置登录界面:
a.首先下载一个登录的模板(html的代码);
b.在html代码前面增加php代码进行登录判断:
代码如下: (此代码为判断登录的用户名及密码是否与数据库一致)
<?php
session_start();
include_once 'admin_global.php';
if((!empty($_POST[username]))&&(!empty($_POST[password]))&&$_POST[submit]){
$r=$db->Get_user_login($_POST["username"],$_POST["password"]);
}
?>
这样,一个完整的框架就已经搭建完成了。现在根据各自的功能的需要,进行2次开发了。
