检查控制器中的特定提交按钮值(Yii2)

Question

如何检查控制器中的提交按钮值(Yii2).我正在使用多个提交按钮.

我试过简单的PHP代码.但它不起作用.

if(isset($_POST['next']) && $_POST['next']=='gotocartfive') 

视图中的代码是:

<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'status')->checkbox(); ?>

</div>

<div class="form-group">
    <?php echo Html::submitButton('NEXT',array('value'=>'gotocartfive','name' => 'next','id'=>'next_summary','class'=>'btn btn-primary pull-right')); ?>
    <?php echo Html::submitButton('PREVIOUS',array('value'=>'previous_four','name' => 'cartfour','class'=>'btn btn-primary pull-left')); ?>
</div>  
<?php ActiveForm::end(); ?>

Answer 1

<?= Html::submitButton('Submit 1', ['name' => 'submit', 'value' => 'submit_1']) ?>
<?= Html::submitButton('Submit 2', ['name' => 'submit', 'value' => 'submit_2']) ?>

PHP

If (\Yii::$app->request->isPost) {
   switch (\Yii::$app->request->post('submit')) {
      case 'submit_1':

      case 'submit_2':

   }
}

当您按Enter键提交表单时(不单击任何提交按钮),submit_1将是默认值.
