php - Yii2 Sum of a Column Based on Filter Option -


i have gridview , 6 filter options placed on radio buttons. when click filter, gridview change based on filter being clicked. here's picture:

enter image description here

now, want total converted amount of table based on filter chosen. example, if choose draft filter, table show draft reimbursements , sum converted amount , total placed @ top right side above table shown in photo.

i tried googling solutions 1 find no answer. here's snippet of code in controller:

$refreshdata = false;  if (isset(yii::$app->request->getbodyparams()['sortby'])) {     $refreshdata = true;     $sortby = yii::$app->request->getbodyparams()['sortby']; } else {     $sortby = 'show all';     $dataprovider = new activedataprovider([         'query' => reimbursement::find()->where(['company_id' => new \mongoid($session['company_id'])])     ]); }  // reimbursements $reimbursements = reimbursement::findall(['company_id' => new \mongoid($session['company_id'])]);  if (isset(yii::$app->request->getbodyparams()['sortby'])) {     if(yii::$app->request->getbodyparams()['sortby'] != '' && yii::$app->request->getbodyparams()['sortby'] != 'show all') {         $refreshdata = true;         $reimbursements = reimbursement::findall(['company_id' => new \mongoid($session['company_id']), 'status' => yii::$app->request->getbodyparams()['sortby']]);         // $ids = [];         // foreach ($reimbursements $i => $model) {         //     $ids[] = $model['_id'];         // }          // $command = yii::$app->db->createcommand('select sum(total) estimate `_id` in ('.implode(',',$ids).')'); // please use prepared statement instead, proof of concept         // $sum = $command->queryscalar();     } elseif (yii::$app->request->getbodyparams()['sortby'] == 'show all') {          $refreshdata = true;     } }  $dataprovider = new arraydataprovider([     'allmodels' => $reimbursements, ]);  if($refreshdata) {     return $this->renderpartial('_index', [         'dataprovider' => $dataprovider,      ]); }  $dataprovider->pagination->pagesize = 10; return $this->render('index', [     'searchmodel' => $searchmodel,     'dataprovider' => $dataprovider,     'rmodel' => $rmodel, ]);

as may have noticed commented lines of code below if(yii::$app->request->getbodyparams()['sortby'] != '' && yii::$app->request->getbodyparams()['sortby'] != 'show all') condition. tried 1 , doesn't work.

how implement this? 

        $reimbursements = reimbursement::find()->where(['company_id' => new \mongoid($session['company_id'])]);      if (isset(yii::$app->request->getbodyparams()['sortby'])) {         $refreshdata = true;         $sortby = yii::$app->request->getbodyparams()['sortby'];         $reimbursements->andwhere(['status' => yii::$app->request->getbodyparams()['sortby']]);     } else {         $refreshdata = false;         $sortby = 'show all';     }      $dataprovider = new activedataprovider([         'query' => $reimbursements,     ]);      $totalsum = $reimbursements->sum('total');

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
