thinkPHP分页功能实例详解

本文实例讲述了thinkPHP分页功能。分享给大家供大家参考，具体如下：

interface ServiceInterFace：

<?php/** * InterFaceService * @author yhd */namespace Red;interface ServiceInterFace {  /**   * 实例化当前类   */  public static function getInstance();}

StaticService 静态服务类：

<?php/** * 静态服务类 * StaticService * @author yhd */namespace Red;class StaticService{  protected static $data;  /**   * 设置静态数据   * @param string $key key   * @param mixed $data data   * @return mixed   */  public static function setData($key,$data){    self::$data[$key] = $data;    return self::$data[$key];  }  /**   * 通过引用使用静态数据   * @param string $key key   * @return mixed   */  public static function & getData($key){    if(!isset(self::$data[$key])){      self::$data[$key] = null;    }    return self::$data[$key];  }  /**   * 缓存实例化过的对象   * @param string $name 类名   * @return 对象   */  public static function getInstance($name){    $key = 'service_@_'.$name;    $model = &self::getData($key);    if($model === null){      $model = new $name();    }    return $model;  }  /**   * html转义过滤   * @param mixed $input 输入   * @return mixed   */  public static function htmlFilter($input){    if(is_array($input)) {      foreach($input as & $row) {        $row = self::htmlFilter($row);      }    } else {      if(!get_magic_quotes_gpc()) {        $input = addslashes($input);      }      $input = htmlspecialchars($input);    }    return $input;  }}

abstract AbProduct  抽象商品管理类：

<?php/*** 抽象商品管理类* AbProduct.class.php* @lastmodify 2015-8-17* @author yhd*/namespace Red/Product;abstract class AbProduct{  public $errorNum;  /*  *返回错误信息  *@param $errorNum 错误代码  */  public function GetStatus(){    $errorNum = $this->errorNum;    switch($errorNum){        case 0:            $data['status'] = 0;            $data['message'] = '收藏成功';            break;        case 1:            $data['status'] = 1;            $data['message'] = '收藏失败';            break;        case 2:            $data['status'] = 2;            $data['message'] = '已收藏';            break;        case 3:            $data['status'] = 3;            $data['message'] = '未登陆';            break;        case 4:            $data['status'] = 4;            $data['message'] = '缺少参数';            break;        default:            $data['status'] = 200;            $data['message'] = '未知错误';    }    return $data;  }

MemberModel 会员模型：
