如何在Yii中发布复选框以执行操作？

Question

I want to post a checkbox to action and print alert if the checkbox is checked, here is my code:

view:

echo CHtml::checkBox('hi');
echo CHtml::button('Search', array('onclick' => 'js:document.location.href="index"'));

controller:

public function actionIndex()
    {

            $model = Jobs::model()->findAll();
            $model2 = Tags::model()->findAll();


            if(isset($_POST['hi']))
                        echo "<script>alert('hello');</script>";


            $this->render('index', array('model'=>$model, 'model2'=>$model2));
    }

when I check the checkbox and click the button nothing is happened, where is the error in my code?

You just redirect your page to actionIndex. You must SUBMIT your form instead of redirecting it. Take a look:

    echo CHtml::beginForm(Yii::app()->createUrl('index'), 'POST');
    echo CHtml::checkBox('hi');
    echo CHtml::submitButton('Search');
    echo CHtml::endForm();

If you try:

CVarDumper::dump($_POST,56789,true);

You can see the POST value after submitting the form.

Or you can do it via java-script in your button:

//if you have created a form
echo CHtml::button('Search', array('onclick' => 'this.submit();'));
