Yii2 how to pass variable from view and send to another source - model-view-controller

Question

all
My point is.
I need to create a custom report by passing a value from $valiable in view -> controller
my question is how to pass value from $valiable
now I can get value from another system by fix value in $valiable in controller.php
but I need to pass $valiable from view.php that selected after submit button.
something like this
here my code
index.php
<?php $form = ActiveForm::begin(); ?>
<div class="col-xs-12 col-sm-6 col-md-3">
<label class="control-label"> field1 </label>
<?php echo Select2::widget([
'name' => 'field1',
'data' => Report::itemAlias('field1'),
'options' => [
'placeholder' => 'Select Cost Center...',
],
'pluginOptions' => ['allowClear' => true,],
]); ?>
</div>
<div class="col-xs-12 col-sm-6 col-md-3">
<label class="control-label"> field2 </label>
<?php echo Select2::widget([
'name' => 'field2',
'data' => Report::itemAlias('field2'),
'options' => [
'placeholder' => 'Select Fund Center...',
],
'pluginOptions' => ['allowClear' => true,],
]); ?>
</div>
<div class="form-group" >
<?= Html::submitButton('process', ['class' => 'btn btn-warning ']) ?>
</div>
<?php ActiveForm::end(); ?>
in ReportController.php
public function actionIndex ()
{
$array = []; // for array result
$field1 = ''; // if fix value $field1 = 'a'; can pass a to $result
$field2 = ''; // if fix value $field2 = 'b'; can pass b to $result
if (Yii::$app->request->isPost)
{
$FISTL = $_POST['field1']; // view ~field1
$FIPEX = $_POST['field2']; // view ~field2
}
if($field1 !== '' && $field1 !== ''){ *// add if condition for get variable*
$connection = Yii::$app->sconnection->connectionToAnotherSystem(); // connection to another system
$result = $connection->getValue([
'field1' => $field1, // if fix value $field1 = 'a'; can pass a to $result
'field2' => $field2, // if fix value $field2 = 'b'; can pass b to $result
]);
$array = array(['value' =>$result]);//return value from another system
} $dataProvider = new ArrayDataProvider([
'allModels' => $array,
]);
return $this->render('index',
[
'dataProvider' => $dataProvider, // true data
]);
}
EDIT : i got what I want. in controller.php add if condition.

Answer 1

I don't get it at all
But suposing you have the other system's response in $result, it looks like an array; then you are asigning an array in the variable $array that have an assosiative value called 'value'.
The way to get the field1 value is
$array['value']['field1']
You should have a GridView like this in your view php file
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
...
'value.field1',
'value.field2',
...
],
]); ?>
That should works
