从窗体字段获取数据到按钮值yii2

Question

我有一个表单域和一个窗体中的按钮。该按钮应从表单字段获取数据并将该值作为参数传递。请告诉我如何从表单字段获取数据并传递值。

表单字段 -

<?= $form->field($model, 'productname')->textInput(['maxlength' => true]) ?> 

按钮

<?= Html::a('Search', ['/stock/sellitem/printproductledger3', 'productname' => '8904187001305'], ['class'=>'btn btn-primary']) ; ?> 

上面的例子做工精细，因为该值已经在这里给出'productname' => '8904187001305' 我需要做的是从表单字段中获得的价值'8904187001305' 。请帮忙。

的actionIndex

public function actionIndex2() 
    { 
     $searchModel = new SellitemsbdtSearch(); 
     $dataProvider = $searchModel->search(Yii::$app->request->queryParams); 

     return $this->render('_formbtdt', [ 
      'model' => $searchModel, 
     ]); 
    } 

该指数导致_formdtbt

'action' => ['/stock/sellitem/printproductledger3',], 

<?= $form->field($model, 'productname')->textInput(['maxlength' => true,]) ?> 
<?= Html::submitButton('Search', ['class' => 'btn btn-primary']) ?> 

控制器动作printproductledger3

public function actionPrintproductledger3() { 

     $searchModel1 = new SellitemsbdtSearch(); 
     $dataProvider1 = $searchModel1->search(Yii::$app->request->get()); 
     $searchModel2 = new PuritemsbdtSearch(); 
     $dataProvider2 = $searchModel2->search(Yii::$app->request->get()); 
return $this->render('_printproductledgerbtdt', [ 
      'dataProvider1' => $dataProvider1, 
      'searchModel1' => $searchModel1, 
      'searchModel2' => $searchModel2,   
      'dataProvider2' => $dataProvider2, 
     ]); 
    } 

嗯，我想我已经指出了错误的问题。问题是模型sellitemsbdtSearch正在过滤，但puritemsbdtSearch没有得到过滤。

搜索型号sellitemsbdtSearch

public function search($params) 
    { 
     //$query = Sellitem::find(); 
     $query = Sellitem::find() 
       ->joinWith(['siSs']) 
       ->select(['sellsum.ss_date as date','si_iupc','si_idesc', 'concat("By sales to Tax Invoice ", sellsum.ss_invno) as particular', 'si_qty as sellqty','(si_qty * si_rate) as value']) 
       ->orDerBy([ 
         'sellsum.ss_date'=>SORT_DESC, 
        ]); 
     // add conditions that should always apply here

      'query' => $query, 
      'pagination' => ['pageSize' => 10000000000,],

     if (!($this->load($params) && $this->validate())) {

你可以用这种方式为模型的值发送到你的动作

<?php $form = ActiveForm::begin([ 
     'action' => ['your_action'], 
     'method' => 'your_method ', /// get or post 
    ]); ?> 
    <?= $form->field($model, 'productname')->textInput(['maxlength' => true]) ?> 

    <div class="form-group"> 
     <?= Html::submitButton('Search', ['class' => 'btn btn-primary']) ?> 
     <?= Html::resetButton('Reset', ['class' => 'btn btn-default']) ?> 
    </div> 

    <?php ActiveForm::end(); ?> 

一次提交你不能以normale yii2的方式获得价值

对于不具有相同的realetd模型，并提交作为第一个你应该使用

// in $get try retrive the content of $get (in this case i related your yourModel1) 
$get = Yii::$app->request->get(['yourModel1']) 
// and the use the value for searching in your model2 with the proper value 
// obviously you should adatp the name in this sample with the proper ones 
$searchModel2 = new PuritemsbdtSearch(); 
    $dataProvider2 = $searchModel2->search(['YourModelSearch2Name'=>['yourAttributeYouNeed'=>$get['productname']]]);
