Yii passing array from view to controller

In my view I have a popup with a few buttons where user can select multiple options and I keep track what are selected and put them in an array using Jquery like below:


            <div class="modal-body">

                <div id="step1"> 

                    <h2 class="modal-subtitle">Let's get started</h2>

                    <br>

                    <p>Hi, I'm Eleven, Product Manager at MaGIC. I'm here to make sure you'll have a good kickstart. Let's have a quick walkthrough.</p>

                    <button class="btn-forward btn-sd-green" id="btnEndStep1">Forward</button>

                </div>

                <div id="step2" class="hideMe"> 

                    <!-- <h2 class="modal-subtitle"></h2> -->

                    <br>

                    <p style="margin-bottom: 20px;">Now let's customise your Central Dashboard based on your interest</p>

                    <!-- <?php echo $username ?> -->

                    <div class="section group-services">


                    <?php foreach ($listServices as $list): ?>


                        <a class="col-services span_1_of_3">

                        <?php echo $list['title']?>

                        </a>

                     

                    

                  <?php endforeach; ?>

                  </div>

                    <button class="btn-forward btn-sd-green" id="btnEndStep2">Forward</button>

                </div>

                <div id="step3" class="hideMe"> 

                    <h2 class="modal-subtitle">That's awesome!</h2>

                    <br>

                    <p>See, isn't that quick? </p><p>Now go ahead and explore your Central dashboard. If you need more help, we've prepared everything in <a href="/cpanel/guidelines">Guideline</a></p>

                    <button class="btn-forward btn-sd-green" id="btnEndStep3">Got it!</button>

                </div>

            </div>






    	$(function () {

            var selected = [];

		    $(".col-services.span_1_of_3").click(function (e) {

		        $(this).toggleClass("active");

		        e.preventDefault(); /*ignores actual link*/

		    });


            $(".col-services.span_1_of_3").click(function (e) {

             

                if ($(this).hasClass('active')) {

                    selected.push($(this).text());

                    console.log(selected);

                  } else {

                    var index = selected.findIndex(function() {return $(this).text()});

                    selected.splice(index, 1);

                    console.log(selected);


                  }


            });




		});

My controller action for this view is as below:




	public function actionIndex()

	{

        //get user's email

		$username = Yii::app()->user->username;


        //get a list of services available for user to pick

		$tmps = HUB::listServiceBookmarkable();

		foreach($tmps as $tmp)

		{

			$result[] = $tmp->toApi();

		}


        //set user's selection

		$setService = HUB::setServiceBookmarkByUser($username, $result);

		foreach($setService as $ss)

		{

			$ssResult[] = $ss->toApi();

		}

		


		$this->render('index',array(

			'username' => $username,

			'listServices'=>$result,

			'setResult' => $ssResult

		));

	}



My question is that how do I pass the array of user’s selection in comma separated format from my view to its necessary api in my controller?:


$setService = HUB::setServiceBookmarkByUser($username, $result);

What’s the best way to do it?
