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);
