分享下smarty+adodb+php分页方法，模板设计采用的是smarty模板，链接数据库使用的是adodb技术。
设计思路：
下载smarty，adodb，到站点根目录page下的fenye文件夹下。
专题推荐：php分页代码大全
smarty:
在smarty文件夹下分别建立三个文件夹templates，templates_c,smarty_cache.
如图：
1，对smarty进行配置操作的文件，smarty_inc.php代码：
复制代码 代码示例:
<?php
include_once("smarty.class.php");
class smartyproject extendssmarty
{
function __construct()
{
$this->config_dir="smarty/smarty/config_file.class.php";
$this->caching=false;
$this->template_dir = "smarty/templates/";
$this->cache_dir = "smarty/smarty_cache/";
$this->left_delimiter = "{";
$this->right_delimiter = "}";
}
}
?>
2，adodb，连接数据库类：
复制代码 代码示例:
class conndb
{
var $dbtype;
var $host;
var $user;
var $pwd;
var $dbname;
var $debug;//false不显示侦错信息，反之，显示
var $conn;
function __construct($dbtype,$host,$user,$pwd,$dbname,$debug=false)
{
$this->dbtype = $dbtype;
$this->host = $host;
$this->user = $user;
$this->pwd = $pwd;
$this->dbname = $dbname;
$this->debug = $debug;
}
//实现数据库的连接并返回连接对象(个人理解可以说返回adodb对象)
function getconnid()
{
include_once('adodb5/adodb.inc.php');
if($this->dbtype == "
mysql" || $this->dbtype == "mssql")
{
if($this->dbtype == "mysql")
{
$this->conn = newadoconnection("mysql");//创建adodb对象，声明数据库类型为mysql
}
else
{
$this->conn = newadoconnection("mssql");
}
$this->conn->connect($this->host,$this->user,$this->pwd,$this->dbname);
}
else if($this->dbtype == "access")
{
$this->conn = newadoconnection("access");
$this->conn->connect("driver={microsoft access driver (*.mdb)};dbq=".$this->dbname.";uid=".$this->user.";pwd=".$this->pwd.";");
}
$this->conn->execute("set names utf-8");
if($this->dbtype == "mysql")
{
$this->conn->debug = $this->debug;
}
return $this->conn;
}
function closeconnid()//关闭与数据库的连接
{
$this->conn->disconnection();
}
}
3，数据库操作类：
复制代码 代码示例:
class admindb
{
var $sqlstr;
var $conn;
var $sqltype;
var $rs;
var $array;
function execsql($sqlstr,$conn)
{
$rs = $conn->execute($sqlstr);
$sqltype = strtolower(substr(trim($sqlstr),0,6)); //strtolower() 函数把
字符串转换为小写。
if($sqltype = "select")
{
$array = $rs->getrows(); // 类似mysql_fetch_array函数返回的数组
if(count($array) == 0 || $rs == false)
{
return false;
}
else
{
return $array;
}
}
else if($sqltype = "update"||$sqltype = "insert"||$sqltype = "delete")
{
if($rs)
{
return true;
}
else
{
return false;
}
}
}
}
4，分页类：
复制代码 代码示例:
class seppage
{
var $rs;
var $pagesize;
var $nowpage;
var $array;
var $conn;
var $sqlstr;
function showdate($sqlstr,$conn,$pagesize,$nowpage)
{
if(!isset($nowpage)||$nowpage=="")
{
$nowpage = 1 ;
}
else
{
$this->nowpage = $nowpage;
}
$this->pagesize = $pagesize;
$this->conn = $conn;
$this->sqlstr = $sqlstr;
$this->rs = $this->conn->pageexecute($this->sqlstr,$this->pagesize,$this->nowpage);
//pageexecute($sql, $nrows, $page, $inputarr=false) 使用资料集的页码功能，叁数 $page 是以 1 为启使值
$this->array = $this->rs->getrows();
if(count($this->array) == 0 || $this->rs == false)
{
return false;
}
else
{
return $this->array;
}
}
function showpage($contentname,$utits,$anothersearchstr,$class)
{
$allrs=$this->conn->execute($this->sqlstr);
$record=count($allrs->getrows());
$pagecount=ceil($record/$this->pagesize);
$str.="共有".$contentname." ".$record." ".$utits." 每页显示 ".$this->pagesize." ".$utits." 第 ".$this->rs->absolutepage()." 页/共 ".$pagecount." 页";
$str.=" ";
if(!$this->rs->atfirstpage())
{
$str.="<a href=".$_server['php_self']."?page=1".$anothersearchstr." class=".$class.">首页</a>";
}
else
{
$str.="<font color='#555555'>首页</font>";
}
$str.=" ";
if(!$this->rs->atfirstpage())
{
$str.="<a href=".$_server['php_self']."?page=".($this->rs->absolutepage()-1).$anothersearchstr." class=".$class.">上一页</a>";
}
else
{
$str.="<font color='#555555'>上一页</font>";
}
$str.=" ";
if(!$this->rs->atlastpage())
{
$str.="<a href=".$_server['php_self']."?page=".($this->rs->absolutepage()+1).$anothersearchstr." class=".$class.">下一页</a>";
}
else
{
$str.="<font color='#555555'>下一页</font>";
}
$str.=" ";
if(!$this->rs->atlastpage())
{
$str.="<a href=".$_server['php_self']."?page=".$pagecount.$anothersearchstr." class=".$class.">尾页</a>";
}
else
{
$str.="<font color='#555555'>尾页</font>";
}
if(count($this->array)==0 || $this->rs==false)
{
return "";
}
else
{
return $str;
}
}
}
5，文章字符转换处理的类：
复制代码 代码示例:
class usefun
{
function unhtml($text)
{
$content=(nl2br(htmlspecialchars($text)));//htmlspecialchars() 函数把一些预定义的字符转换为 html 实体,nl2br() 函数在字符串中的每个新行 (/n) 之前插入 html 换行符 (<br />)。
$content=str_replace("[strong]","<strong>",$content);
$content=str_replace("[/strong]","</strong>",$content);
$content=str_replace("[em]","<em>",$content);
$content=str_replace("[/em]","</em>",$content);
$content=str_replace("[u]","<u>",$content);
$content=str_replace("[/u]","</u>",$content);
$content=str_replace("[font color=#ff0000]","<font color=#ff0000>",$content);
$content=str_replace("[font color=#00ff00]","<font color=#00ff00>",$content);
$content=str_replace("[font color=#0000ff]","<font color=#0000ff>",$content);
$content=str_replace("[font face=楷体_gb2312]","<font face=楷体_gb2312>",$content);
$content=str_replace("[font face=宋体]","<font face=新宋体>",$content);
$content=str_replace("[font face=隶书]","<font face=隶书>",$content);
$content=str_replace("[/font]","</font>",$content);
//$content=str_replace(chr(32)," ",$content);
$content=str_replace("[font size=1]","<font size=1>",$content);
$content=str_replace("[font size=2]","<font size=2>",$content);
$content=str_replace("[font size=3]","<font size=3>",$content);
$content=str_replace("[font size=4]","<font size=4>",$content);
$content=str_replace("[font size=5]","<font size=5>",$content);
$content=str_replace("[font size=6]","<font size=6>",$content);
$content=str_replace("[fieldset][legend]","<fieldset><legend>",$content);
$content=str_replace("[/legend]","</legend>",$content);
$content=str_replace("[/fieldset]","</fieldset>",$content);
return $content;
}
}
将以上四个类全部放到一个类文件system.class.inc.php里.
另外几个文件：
1、system.inc.php:
复制代码 代码示例:
<?php
session_start();
include_once("smarty_inc.php");
include_once("system.class.inc.php");
//数据库连接类实例化
$connobj = new conndb("mysql","localhost","root","vertrigo","db_fenye",false);
$conn = $connobj->getconnid();
//数据库操作类实例化
$admindb = new admindb();
//分页类实例化
$seppage=new seppage();
//使用常用函数类实例化
$usefun=new usefun();
//调用smarty模板
$smarty=new smartyproject();
function unhtml($params)
{
extract($params);
$text=$content;
global $usefun;
return $usefun->unhtml($text);
}
$smarty->register_function("unhtml","unhtml");
?>
2、执行文件，index.php:
复制代码 代码示例:
<?php
include_once("system.inc.php");
$arraybbstell = $admindb->execsql("select * from tb_bookinfo",$conn);
if(!$arraybbstell)
{
$smarty->assign("isbbstell","t");
}
else
{
$smarty->assign("isbbstell",t);
$smarty->assign("arraybbstell",$arraybbstell);
}
$arraybbs = $seppage->showdate("select * from tb_bookinfo",$conn,1,$_get["page"]);
if(!$arraybbs)
{
$smarty->assign("isbbs",f);
}
else
{
$smarty->assign("isbbs",t);
$smarty->assign("showpage",$seppage->showpage("帖子","条","","a1"));
$smarty->assign("arraybbs",$arraybbs);
}
$smarty->display("index.html");
?>
3、解析文件,index.html:
复制代码 代码示例:
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=gb2312">
<title>页模</title>
</head>
<link rel="stylesheet" href="css/css.css"/>
<body>

总结：
需切记smarty，adodb文件引入的相关一些路径问题。
在执行文件index.html中的css路径，图片背景路径都是相对于index.php这个执行文件的（如css/css.cs和index.php在同一级），引入方法是：<link rel="stylesheet" href="css/css.css"/>
adodb的分页函数：pageexecute，absolutepage()当前页码，atfirstpage()首页页码，atlastpage()尾页页码。（个人理解）
$_server['php_self']：当前执行的文件。
smarty的register_function()参考另文。
