参照学习的是《PHP开发典型模块大全》这本书里的例子。
smarty+adodb+php分页,模板设计采用的是smarty模板,链接数据库使用的是ADODB技术,由于PHP初学,smarty和adodb也是初次接触,现记录学习所得,备忘之。
大体的设计思路是这样的:下载smarty,adodb,到站点根目录page下的fenye文件夹下。
Smarty:
在smarty文件夹下分别建立三个文件夹templates,templates_c,smarty_cache.
如图:
对smarty进行配置操作的文件,Smarty_inc.php,代码如下:
<?php
include_once("Smarty.class.php");
class SmartyProject extends Smarty
{
function __construct()
{
$this->config_dir="smarty/Smarty/Config_File.class.php";
$this->caching=false;
$this->template_dir = "smarty/templates/";
$this->compile_dir = "smarty/templates_c/";
$this->cache_dir = "smarty/smarty_cache/";
$this->left_delimiter = "{";
$this->right_delimiter = "}";
}
}
?>
ADODB:
连接数据库类:
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();
}
}
数据库操作类:
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;
}
}
}
}
分页类:
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 $str;
}
}
}
另加一个文章字符转换处理的类:
class UseFun
{
function UnHtml($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 />)。
以上四个类全部放到一个类文件system.class.inc.php里. 另外还有几个文件如下: system.inc.php: <?php $smarty->register_function("unhtml","unhtml"); 执行文件,index.php: <?php 解析文件,index.html: <html> 知识点备忘:
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。
