本文实例讲述了cakephp2.X多表联合查询join及使用分页查询的方法。分享给大家供大家参考，具体如下：
格式化参数：

public function getconditions($data){ $this->loadModel("Cm.LoginHistory"); $conditions = array(); foreach ($data as $key=>$val){ if($key=='start_date'){ $conditions['LoginHistory.logintime >=']=trim($val); }elseif ($key=='end_date'){ $conditions['LoginHistory.logouttime <=']=trim($val); }elseif ($key=='selectvsoftid' and $val !=''){ $conditions['LoginHistory.LOGINSUBSYSTEM LIKE']='%'.trim($val).'%'; }elseif ($key=='username' and $val !=''){ $conditions['LoginHistory.USERNAME LIKE']='%'.trim($val).'%'; }elseif ($key=='vdevicename' and $val !=''){ $conditions['LoginHistory.WINDOWNAME LIKE']='%'.trim($val).'%'; }elseif ($key=='selectvsoftid' and $val !=''){ $conditions['LoginHistory.PHDEVICENAME LIKE']='%'.trim($val).'%'; } } return $conditions;} |
分页查询：

$fields = array('LoginHistory.windowname','LoginHistory.loginsubsystem','VirtualDevice.PHDEVICEID','LoginHistory.userid', 'VirtualDevice.SYSTYPEID','UserInfo.USERNAME','"SUM"(LoginHistory.LOGOUTTIME-LoginHistory.LOGINTIME) moument','UserInfo.USERNAME','DeviceInfo.DEVICENAME');$group=array('LoginHistory.windowname', 'LoginHistory.loginsubsystem', 'LoginHistory.userid','UserInfo.USERNAME','DeviceInfo.DEVICENAME','VirtualDevice.SYSTYPEID','VirtualDevice.PHDEVICEID');$this->paginate = array('conditions'=>$conditions,'fields'=>$fields,'group'=>$group,'limit'=>9,'joins' => array( array( 'alias' => 'UserInfo', 'table' => 'SMM_USERINFO', 'type' => 'LEFT', 'conditions' => ' LoginHistory.USERID=UserInfo.USERID ', ), array( 'alias' => 'VirtualDevice', 'table' => 'ET_NMVIRTUALDEVICEINFO', 'type' => 'LEFT', 'conditions' => ' LoginHistory.WINDOWNAME=VirtualDevice.DEVICENAME ', ), array( 'alias' => 'DeviceInfo', 'table' => 'ET_NMDEVICEINFO', 'type' => 'LEFT', 'conditions' => ' VirtualDevice.PHDEVICEID=DeviceInfo.DEVICEID ', ), ));$LoginHistory = $this->paginate('LoginHistory');$this->set('loginhistory',$LoginHistory); |
希望本文所述对大家PHP程序设计有所帮助。
