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：

StaticService 静态服务类：
abstract AbProduct  抽象商品管理类：
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：
userId = getUserInfo(0);  }   /**   * 实例化本类   * @return MemberModel   */  public static function getInstance() {    return StaticService::getInstance(__CLASS__);  }   /**   *  获取登录用户信息   * @param string  $data 查询条件   * @return array   */  public function getUser($data = '') {    if(empty($data)){      return $this->where("id=".$this->userId)->find();    }else{      return $this->field($data)->where("id=".$this->userId)->find();    }  }  /**   * 修改用户信息   * @param array $data   * @param array $where 查询条件   */  public function editUserInfo($data, $where = '') {    if( $this->_before_check($data) === false ){      return $this->error['msg'];    }    if(!empty($where) && is_array($where)){      $condition[ $where[0] ] = array('eq', $where[1]);      return $this->where($condition)->save($data);    }    return $this->where("id=".$this->userId)->save($data);  }  /**   * 获取用户信息   * @param string $data 用户名   * return array()   */  public function checkUserInfo($str, $field = ''){    //注册类型    $info = CheckType($str);    $condition[$info] = array('eq',$str);    if(!empty($field)){      return $this->field($field)->where($condition)->find();    }    return $this->where($condition)->find();  }  /**   * 获取用户信息   * @param array $data 用户名   * return array()   */  public function getAccount($data){    //注册类型    $info = CheckType($data);    $condition['id'] = array('eq',$this->userId);    $condition[$info] = array('eq',$data);    return $this->where($condition)->find();  }  /**   * 修改用户密码   * @param array $data['id']用户ID   * @param $data['passWord']用户密码   * return true or false   */  public function upUserPassById($data){    $condition['id'] = array('eq',$data['id']);    $status = $this->where($condition)->save(array("password"=>md5($data['password'])));    if($status){        return TRUE;    }else {        return FALSE;    }  }  /**   * 校验用户的账号或者密码是否正确   * @param $data['username'] 用户名   * @param $data['password'] 密码   * return true or false   */  public function checkUserPasswd($data= array()){      $type = CheckType($data['username']);      $condition[$type] = array('eq',$data['username']);      $condition['password'] = array('eq',md5($data['password']));       return $this->where($condition)->find();  }  /**   * 网页登录校验token   * @param token string   * return bool   */  public function checkToken($token){      return $this->autoCheckToken($token);  }  /**   * 后台封号/解封   * param int $user_id   */  public function changeStatus($data){    if($this->save($data)){      return true;    }else{      return false;    }  }  protected function _before_check(&$data){    if(isset($data['username']) && empty($data['username'])){      $this->error['msg'] = '请输入用户名';      return false;    }    if(isset($data['nickname']) && empty($data['nickname'])){      $this->error['msg'] = '请输入昵称';      return false;    }    if(isset($data['realname']) && empty($data['realname'])){      $this->error['msg'] = '请输入真名';      return false;    }    if(isset($data['email']) && empty($data['email'])){      $this->error['msg'] = '请输入邮箱';      return false;    }    if(isset($data['mobile']) && empty($data['mobile'])){      $this->error['msg'] = '请输入手机号码';      return false;    }    if(isset($data['password']) && empty($data['password'])){      $this->error['msg'] = '请输入密码';      return false;    }    if(isset($data['headimg']) && empty($data['headimg'])){      $this->error['msg'] = '请上传头像';      return false;    }    return true;  }}
ProductModel 商品模型：
where($condition)->find();  }  /**   * 商品列表   * @param string $limit 查询条数   * @param array $data 查询条件   * @return array 二维数组   */  public function getProList($data = ''){    $condition['onsale'] = array('eq', $data['onsale']); //是否上架    $condition['status'] = array('eq', $data['status']); //状态    $condition['type'] = array('eq', $data['type']);  //分类    if(isset($data['limit']) && isset($data['order']) ){      $return =$this->where($condition)->limit($data['limit'])->order($data['order'])->select();    }else{      $return =$this->where($condition)->select();    }    return $return;  }  /**   * 添加商品   * @param array $data   * @return int   */  public function addProduct($data){    return $this->add($data);  }  /**   * 删除商品   *   */  public function delProduct($id){    $condition['id'] = array('eq', $id);    return $this->where($condition)->delete();  }  /**   * 修改商品   * @param string|int $id   * @param array $data   * @return   */  public function editProdcut($id, $data){    $condition['id'] = array('eq', $id);    return $this->where($condition)->save($data);  }  public function getProductInfo($product){    if(empty($product) || !isset($product['product_id'])){      return array();    }    $info = $this->getProOne($product['product_id']);    $product['name'] = $info['name'];    $product['store_id'] = $info['store_id'];    $product['price'] = $info['price'];    $product['m_price'] = $info['m_price'];    return $product;  }}
ProductManage 商品管理类：
getCollectList($page,$limit);　　　　$showpage = create_pager_html($list['total'],$page,$limit);　　　　$this->assign(get_defined_vars());　　　　$this->display();　　}　　public function cancelCollect(){　　　　$ids = field('ids');　　　　$return = ProductManage::getInstance()->cancelProductCollect($ids);　　　　exit(json_encode($return));　　}}
functions.php 分页函数：
 $v) {      if ($k != 'page') {        $url[] = urlencode($k) . '=' . urlencode($v);      }    }    $url[] = 'page={page}';    $url = '?' . implode('&', $url);  }  if ($total <= $perpage)    return '';  $total = ceil($total / $perpage);  $pagecount = $total;  $total = ($maxpage && $total > $maxpage) ? $maxpage : $total;  $page = intval($page);  if ($page < 1 || $page > $total)    $page = 1;    $pages = '
