php - How to get Submit Button Values in Controller/Action Yii2 -

i'm new in yii2 framework. want submit button name/value in controller/action.

following code:

form:

<?php $form = activeform::begin(); ?>  <?= $form->field($model, 'admin_document_key_id')->dropdownlist(arrayhelper::map(admindocumentkey::find()->all(), 'id', 'key_name'), ['prompt' => 'select']) ?>  <?= $form->field($model, 'key_value')->textinput(['maxlength' => 255]) ?>      <div class="form-group">     <?php if (yii::$app->controller->action->id == "create"): ?>         <?= html::submitbutton('create & add new', ['class' => 'btn btn-primary']) ?>     <?php endif; ?>              <?= html::submitbutton($model->isnewrecord ? 'create' : 'update', ['class' => $model->isnewrecord ? 'btn btn-success' : 'btn btn-primary', 'value'=>'create', 'name'=>'submit']) ?>     <?= html::a('cancel', ['/admindocumentvalue'], ['class' => 'btn btn-warning']) ?>     <?= html::resetbutton('reset', ['class' => 'btn btn-info']) ?> </div> 

controller/action:

public function actioncreate()  {     $model = new admindocumentvalue();      if ($model->load(yii::$app->request->post()) && $model->save()) {         print_r(yii::$app->request->post());         exit;         return $this->redirect(['index', 'id' => $model->id]);     } else {         return $this->render('create', [             'model' => $model,         ]);     }  } 

it showing following output:

array ( [_csrf] => v0fkc09gclqdbhi1brveir8xowcjlefibssygbczgj4dmwc6jzitba== [admindocumentvalue] => array ( [admin_document_key_id] => 1 [key_value] => claims ) )  

but not showing submit button name , value.

i tried $_post & $_request still not working.

any appreciated.

thanks.

resolved myself changing default yii2 buttons this:

<?= html::submitbutton('create & add new', ['class' => 'btn btn-primary', 'value'=>'create_add', 'name'=>'submit']) ?> <?= html::submitbutton($model->isnewrecord ? 'create' : 'update', ['class' => $model->isnewrecord ? 'btn btn-success' : 'btn btn-primary', 'value'=>'create', 'name'=>'submit']) ?> 

then in controller

if (yii::$app->request->post('submit')==='create_add') {     // create add } else {     // submit }
